how did seismographs assist in the development of plate tectonics

Answers

Answer 1

Answer:

Seismographs influenced the theory of plate tectonics. Plate tectonics is the scientific theory that describes how the Earth's surface constitutes large plates moving and interacting to cause earthquakes, volcanic eruptions, and the formation of mountains. Seismographs detect and record vibrations in the Earth's crust. By measuring the arrival times and amplitudes of seismic waves, seismographs determine the location, magnitude, and depth of earthquakes.

In the early 20th century, seismologists began using seismographs to study earthquake patterns and the Earth's interior structure. They discovered that earthquakes occurred in distinct patterns along certain zones and that the Earth's crust was not a continuous, unbroken shell. In the 1960s, seismologists observed that earthquake patterns and other geologic features such as mountain ranges, trenches, and volcanic arcs, correlated with plate boundaries. They also discovered that seismic waves traveled differently through different types of rock, providing evidence for the existence of the Earth's crust and mantle.

These findings, combined with other geological and geophysical observations influenced the theory of plate tectonics. The theory proposes that the Earth's lithosphere (the rigid outermost layer of the Earth) is broken into plates that move relative to each other along boundaries. Seismographs are still used to study plate tectonics today, providing information about earthquake activity and the structure and movement of the Earth's crust.

where do most of foreign born people living in horry county migrate from? (list top 4​

Answers

he population chapter examines population trends and describes the demographic composition of Horry County residents. Population growth and composition influences land

use decisions, determines housing and infrastructure needs,

and impacts the local economy. As Horry County’s population continues to grow, an increased demand for public

safety, community services, and facilities will also increase,

as well as the desire for cultural resources along with access

to natural spaces. Studying a community’s population is

fundamental to any comprehensive plan. Horry County will

need to continue to monitor the permanent and short-term

population into the future to inform decision-making.

POPULATION GROWTH

According to 2015 population estimates, Horry County has

approximately 309,199 permanent residents. The County

has experienced rapid growth since the 1970s, adding over

250,000 permanent residents since that time. In just the last

15 years, there has seen an influx of over 100,000 residents.

The County has one of the highest population growth rates

in the State and is now the fourth most populous county in

South Carolina, behind Greenville, Richland, and Charleston

counties respectively.

The 2015 total population estimate reflects a 14.8% increase

or 39,908 more people since 2010. This reflects growth that

occurred even during a major economic downturn. These

numbers are only expected to escalate. The population is

projected to grow to 584,500 by 2040. While the projections

were refined by the Waccamaw Regional Council of Governments and Horry County Planning and Zoning, population growth is occurring faster than anticipated. It is important to note that the 2020 population projections are already

being surpassed that were developed in 2017 by the South

Carolina Budget and Control Board. Note that these

population numbers and projections do not account

for seasonal population, including snowbirds that live

in the area for the cooler months and tourist and seasonal work population during the summer months.

These estimates will need to be revisited after the release of the 2020 Census.

MUNICIPAL GROWTH

Over the last three decades, all municipalities, with

the exceptions of Atlantic Beach, Aynor, and Surfside Beach, have gained population; however, unincorporated areas have accounted for most of the

growth in recent years. As of 2015, there were 76,118

people that lived in area municipalities, while 233,081

lived in unincorporated Horry County, making up

75.7% of the total County population.

Historically, Horry County’s population has primarily resided along the beach front and near area waterways.

Since the 2000 Census, Horry County’s population has grown further away from the beach, along major highway corridors. Burgess, Socastee, Forestbrook, and Carolina Forest have seen the most growth. Conway, Little

River, and the Hwy 90 corridor have also seen considerable population growth. These areas are expected to

see an increase in development into the future, as many new subdivisions have been preliminarily approved in

these growth areas, but remain to be constructed.

Population growth from 2011-2015 was mainly being driven by individuals that were relocating to Horry County

from neighboring Southern States (50,968 people), other counties in South Carolina (30,959 people), and from

the Northeast (31,379 people). Since 2010, an estimated 139,319 people moved to Horry County. It is estimated

that for domestic migration roughly 36 out of every 1,000 residents and for international migration roughly 369

out of every 1000 residents remain in Horry County (US Census Bureau, migration rates calculated by Governing

July 2017).

New residents are largely moving into the areas east of the Waccamaw River to be close to the beach. This is

due, in part, to those area’s proximity to job centers, housing opportunities, and zoning regulations.

The map below delineates areas of high population density and urban land use resulting in a representation

of the “urban footprint.” There are two types of urban areas: 1- urbanized areas that contain 50,000 or more

people; and 2- small urban clusters that contain at least 2,500 people, but fewer than 50,000 people.

Answers

The following are the volcanic hazards ranked according to their travel distance:

1: (Furthest from the source): Tephra2: High-viscosity lava flow3: (Closest to the source): Low-viscosity lava flow

The volcanic hazards have been ranked according to their travel distance below:

1 (Furthest from the source): Tephra

Tephra is the solidified ash and other debris that is erupted during volcanic eruptions. It can travel very long distances and fall from the sky like rain, often blanketing areas far away from the volcano.

2: High-viscosity lava flow

High-viscosity lava flows are slow-moving, thick, and sticky. They can travel long distances from the volcano, but at a much slower rate than low-viscosity lava flows. As a result, they pose a greater threat to surrounding areas, causing damage to anything in their path.

3 (Closest to the source): Low-viscosity lava flow

Low-viscosity lava flows are fast-moving, runny, and can travel long distances from the source. They spread out in thin sheets and can flow quickly, but they also cool quickly, so they don't usually cause as much damage as high-viscosity lava flows.

which volcanic rock would be associated with the most explosive
volcanie eruptions?

Answers

The volcanic rock associated with the most explosive volcanic eruptions is: Andesite

Andesite is an intermediate volcanic rock that forms when magma of intermediate composition (with a balance of silica, minerals, and gases) solidifies and cools relatively quickly at the Earth's surface. It contains a mix of minerals such as plagioclase feldspar, amphibole, and pyroxene.

Due to its composition, andesitic magma typically has higher viscosity (thickness) and tends to trap gases, resulting in pressure buildup. When this gas-rich, high-viscosity magma erupts, it can lead to extremely explosive volcanic eruptions, producing volcanic hazards such as pyroclastic flows, ash clouds, and volcanic bombs.

Some well-known volcanoes associated with andesitic eruptions include Mount St. Helens in the United States and Mount Pinatubo in the Philippines.

Which of the following is a landform commonly found in karst environments? sinkholes hoodoos calderas hot spots

Answers

Sinkholes are a landform commonly found in karst environments. Hence, Option (A) is correct.

Karst landscapes are characterized by soluble rock formations, such as limestone, that are easily dissolved by water over time.

Sinkholes are a result of this dissolution process. As water percolates through the ground, it erodes and dissolves the underlying soluble rock, creating underground cavities and channels.

Eventually, the roof of these underground spaces becomes unstable and collapses, forming a sinkhole on the surface. Sinkholes can vary in size and shape, ranging from small depressions to large, dramatic craters.

Thus, sinkholes are a distinct feature of karst terrains and can pose risks to infrastructure and human settlements.

The provided statements involve misconceptions regarding fossil fuels and their consumption. While most of the statements are false, there are two specific statements that are inaccurate. It is essential to address these misconceptions in order to have a clear understanding of the global energy landscape and its implications.

Statement II, which claims that the United States consumes 25% of the world's petroleum despite having a smaller population share, is false. Although the U.S. is a significant consumer of petroleum, its consumption does not reach the 25% mark. Similarly, statement III, suggesting that the U.S. holds the world's largest deposits of natural gas and oil due to fracking, is also incorrect.

Will marine food sources keep up with human population growth?

Answers

The marine food sources will not be able to keep up with human growth population.

There isn't much space for hope. There doesn't seem to be enough water available for agriculture to produce enough food to feed the world's 9200 million inhabitants.

Already under water stress, the current population is made worse by the interaction between population expansion and climate change. Additionally, since the middle of the 1980s, worldwide fisheries landings have been dropping, which has added to the current crisis in food production.

The food-producing industry least dependent on the availability of freshwater, marine aquaculture (hereinafter mariculture), will be used to help feed humanity in the twenty-first century.

Although there is still room for growth in northern temperate regions, despite significant intensification (such as a 10-fold increase in the yield of Chinese freshwater aquaculture in 20 years), freshwater aquaculture is becoming increasingly spatially constrained in the tropics and subtropics due to rapid human population growth and the concomitant high requirements for direct use of water and land.

typically, ocean primary productivity in a 1 meter × 1 meter water column will bind ________ of carbon in to molecules of glucose each year?

Answers

In a 1 meter × 1 meter water column, ocean primary productivity typically binds a significant amount of carbon into molecules of glucose each year.

The primary productivity of the ocean refers to the process by which marine organisms, such as phytoplankton, convert sunlight and nutrients into organic matter through photosynthesis. Phytoplankton are microscopic plants that form the basis of the marine food chain and are responsible for a large portion of carbon fixation in the oceans. They take in carbon dioxide from the water and, using sunlight and nutrients like nitrogen and phosphorus, convert it into glucose and other organic compounds through photosynthesis.

The exact amount of carbon bound into glucose in a 1 meter × 1 meter water column can vary depending on various factors, such as the availability of nutrients and light, as well as seasonal and regional variations. However, on average, primary productivity in the ocean is estimated to fix approximately 50 grams of carbon per square meter per year. This means that in a 1 meter × 1 meter water column, a substantial amount of carbon, in the form of glucose molecules, would be bound each year.

It's important to note that the estimate provided is a general approximation and can vary across different marine ecosystems. Nonetheless, the primary productivity of the ocean plays a crucial role in the global carbon cycle, as it sequesters significant amounts of carbon dioxide from the atmosphere and contributes to the regulation of Earth's climate.

Calculate the mass of N2H4 that will be in the reaction vessel once the reactants have reacted as much as possible. Assume 100 % yield.

Answers

The mass of N₂H₄ which will be in the reaction vessel once the reactants have reacted as much as possible will be 0 g.

To calculate the mass of N₂H₄ remaining in the reaction vessel, we need to determine the limiting reactant first. The limiting reactant is the one that is completely consumed in the reaction and determines the maximum amount of product formed. We can compare the number of moles of each reactant to find the limiting reactant.

The molar mass of N₂H₄ (hydrazine) is 32.05 g/mol, and the molar mass of N₂O₄ (dinitrogen tetroxide) is 92.01 g/mol.

First, let's calculate the number of moles for each reactant:

Moles of N₂H₄ = mass / molar mass

= 28.5 g / 32.05 g/mol

≈ 0.889 mol

Moles of N₂O₄ = mass / molar mass

= 74.9 g / 92.01 g/mol

≈ 0.814 mol

According to the balanced equation, the stoichiometric ratio between N₂H₄ and N₂O₄ is 2:1. Therefore, for complete reaction, 2 moles of N₂H₄ react with 1 mole of N₂O₄.

From the given moles, we can see that the mole ratio of N₂H₄ to N₂O₄ is greater than 2:1, which means N₂O₄ is the limiting reactant. This implies that all 0.814 mol of N₂O₄ will react, and N₂H₄ will be in excess.

To determine the mass of N₂H₄ remaining, we can use the stoichiometry of the reaction. Since all of the N₂O₄ reacts and N₂H₄ is in excess, we can calculate the moles of N₂H₄ reacted using the mole ratio of the reaction (2:1);

Moles of N₂H₄ reacted = (0.814 mol N₂O₄) × (2 mol N₂H₄ / 1 mol N₂O₄) = 1.628 mol N₂H₄

Now we can calculate the mass of N₂H₄ remaining in the reaction vessel;

Mass of N₂H₄ remaining = (total moles of N₂H₄ - moles of N₂H₄ reacted) × molar mass of N₂H₄

Mass of N₂H₄ remaining = (0.889 mol - 1.628 mol) × 32.05 g/mol

Mass of N₂H₄ remaining = -0.739 mol × 32.05 g/mol

≈ -23.65 g

Since the calculated mass is negative, it indicates that N₂H₄ is completely consumed in the reaction, and there is no N₂H₄ remaining in the vessel.

Therefore, the mass of N₂H₄ that will be in the reaction vessel once the reactants have reacted as much as possible is 0 g.

do fracture zones near transform boundaries play a role in plate motion?

Answers

fracture zones near transform boundaries play a significant role in plate motion by accommodating horizontal displacement between plates and aiding in the release of accumulated stress and strain.

Transform faults are characterized by the sliding motion of two adjacent plates in opposite directions. As the plates move, stress and strain accumulate along the transform fault, resulting in the formation of fractures in the Earth's crust. These fractures, known as fracture zones, often extend beyond the transform fault itself.Fracture zones play a role in plate motion by accommodating the horizontal displacement between plates. They act as zones of weakness in the Earth's crust, allowing the plates to slide past each other more easily.

As the transform boundary experiences stress and deformation, the movement along the fracture zones helps to relieve the built-up strain.Additionally, fracture zones can contribute to the formation of new lithosphere. Along fracture zones, magma can rise from the mantle and solidify, creating new crust and contributing to the spreading of the seafloor.

What's the connection between Mount Rainier and the plate boundaries along the coast of the Pacific Northwest?

Answers

Answer:

Mount Rainier is a stratovolcano located in the state of Washington, in the Pacific Northwest region of the United States. The volcano is situated on the boundary of the North American Plate and the Juan de Fuca Plate, which is part of the larger boundary known as the Cascadia subduction zone. This boundary is where the Juan de Fuca plate is being subducted beneath the North American plate.

The Cascadia subduction zone is a long and active plate boundary that extends from northern California to southern British Columbia. Along this boundary, the Juan de Fuca plate is moving beneath the North American plate, creating a zone of active volcanism, earthquakes and deformation. The subduction of oceanic crust beneath the North American plate is responsible for the creation of the Cascade Range, including Mount Rainier.

Mount Rainier is an active volcano and one of the most dangerous in the region. It is a reminder of the ongoing tectonic activity along the Cascadia subduction zone and the potential for future volcanic eruptions and earthquakes in the Pacific Northwest.
