what changes in the crust do scientists look for when using seismology and seismic networks to mitigate volcanic hazards? choose one: a. noise/vibrations caused by magma moving through rocks b. the composition of gases coming from a volcano c. lava flowing from a volcanic crater d. temperature changes in magma beneath the volcano

Answers

Answer 1

When using seismology and seismic networks to mitigate volcanic hazards, scientists primarily look for noise/vibrations caused by magma moving through rocks. These vibrations are known as volcanic earthquakes. Therefore, option A is correct.

What are volcanic earthquakes?

When magma, gas, or other fluids move within or beneath a volcano, seismic activity known as volcanic earthquakes takes place. These earthquakes can reveal crucial details regarding the behavior of magma and other volcanic fluids and are frequently precursors to volcanic eruptions.

Volcanic earthquakes often have minor Richter scale magnitudes, with the majority falling between 0 and 3. Nonetheless, they can happen at little depths (less than 10 km), and locals who live close to the volcano can feel them. Volcanic earthquakes can occasionally also cause landslides and rockfalls on the volcano's sides, which might raise the danger of volcanic risks.

Seismometers, tiltmeters, and GPS stations are just a few of the tools seismologists employ to keep track on volcanic earthquakes. Scientists can better understand the dynamics of magma inside a volcano and make more precise predictions about when a volcanic eruption may take place by examining the frequency, duration, and other features of these earthquakes. This knowledge can be put to use to protect the neighboring inhabitants and lessen any possible risks caused by volcanic activity.

do a little internet research to find where the longest such record has been obtained. the site is high on a shield volcano that lies in a u.s. state. list the state, the volcano, and the year scientists began measuring atmospheric gas concentrations there.

Answers

Anywhere there is basaltic (and occasionally andesitic) volcanism, including oceanic hot spot tracks like the Hawaiian Islands, shield volcanoes can be found. They might be found at spreading ridges in the middle of the ocean.

In reference to its low profile, which resembles a warrior's shield resting on the ground, a shield volcano, is a particular form of volcano. It is created by the eruption of lava that is very fluid (low viscosity), traveling further and forming thinner flows than lava that is released from a stratovolcano, which is more viscous. The shield volcano's characteristic shape is created by the slow deposition of wide sheets of lava brought on by repeated eruptions.

Anywhere that flowing low-silica lava touches a stony planet's surface is where shield volcanoes can be discovered. They are particularly typical of ocean island volcanism connected to hot areas or continental rift volcanism, though.  Among these are some of the planet's biggest volcanoes, like Tamu Massif and Mauna Loa. Other planets of the solar system have enormous shield volcanoes.

Answers

In 1965, geologist J. Tuzo Wilson postulated that the earth's surface layer was made up of hard plates that were separated, joined, or slid past one another by three different sorts of boundaries.

At divergent boundaries, new crust is created as the plates separate from one another. Crust breaks at convergence borders where plates collide. Plates can move past one another horizontally at transform boundaries without forming or breaking crust.

Oceanic and continental plates can collide to create oceanic-oceanic borders, oceanic and continental plates can collide to create oceanic-continental boundaries, or continental and oceanic plates can collide when the plates converge (forming continental-continental boundaries).

A river such as Mississippi is likely to have a greater capacity than a small mountain stream. The stream has limited water supply, unlike a river.

What is a river?A river is a large natural stream of freshwater that flows in a channel towards an ocean, sea, lake, or another river. It is formed through precipitation, underground water, and other water sources. Rivers are an important part of the natural environment and help maintain the ecological balance of the earth.

What is a mountain stream?A mountain stream is a small, narrow stream that flows in a steep gradient down a mountain. It is usually fed by snow and ice, which melt during spring and summer.

Mountain streams often have clear water with a high mineral content and a cool temperature because of their high altitude and the surrounding vegetation.So, to answer the question, a river like Mississippi is more likely to have a greater capacity than a small mountain stream due to the difference in the amount of water supply.

investigate abaout tools used by geographers

Answers

At its heart, a map is a representation of a physical location on Earth. Various charts perform various tasks. From a world map showing nations to a comprehensive strolling plan of every route on a college campus, the most fundamental map displays the physical characteristics of a location. Other maps can provide additional information about a region, such as a landmass that has been color-coded according to the languages spoken on it or the main exports, or a map that shows the relative altitudes in a hilly region.

The Precision of Surveying Equipment

You've probably seen these tools used by building workers while stuck in traffic, but geographers use them to do the same thing for their employment. The most well-known is the theodolite, a level lens mounted on a tripod that aids in measuring relative distance and elevation. Geographers use the theodolite in conjunction with a plumb line and measuring ruler to precisely evaluate even minor details of an area.

GPS stands for Global Positioning System.

Global Positioning Systems (GPS) aid navigation by providing comprehensive information about your location and the geographical environment around you. This may be the geography tool you are most familiar with, aside from maps. Global Information Systems and Global Directional Systems are tools that work in tandem. GIS is a library of geographic information that is constantly updated by scholarly, commercial, and military sources, whereas GPS aids navigation by using a database rather than a live satellite feed. Geographers use all three methods to gain access to what is already known about the Earth in order to aid in ongoing study.

Photographic Evidence from Remote Imaging

Geographers had to make maps based on observations and measurements taken on the ground until the middle of the twentieth century. Geographers can now draw maps and make observations based on photos taken from the same perspective as a map of the area, thanks to the invention of reliable air travel and, later, satellite imaging. Geographers can now use remote images to record information beyond the visible spectrum, such as magnetic activity, infrared temperature, and subterranean water levels, thanks to advances in technology.

Using reliable sources of information, collect data comparing the population growth of two countries in each of the following regions: Asia, Europe, and Africa. Organize your data into at least three categories, such as birth rates, death rates, and population growth rates. Write a statement about the data for each region. What are the similarities and differences between the data for these regions?

Answers

These differences can be attributed to various factors, including cultural norms, socioeconomic conditions, and government policies regarding family planning and healthcare  unropes generally has lower birth rates, leading to population decline or slow growth, while Asia and Africa have higher birth rates, resulting in faster-growing populations.

Asia:

Country 1: China

Birth rate: 11.4 births/1,000 population

Death rate: 7.8 deaths/1,000 population

Population growth rate: 0.36%

Country 2: India

Birth rate: 18.2 births/1,000 population

Death rate: 7.3 deaths/1,000 population

Population growth rate: 1.08%

Statement: In Asia, both China and India have relatively high birth rates compared to the death rates, indicating a positive population growth. However, India experiences a higher birth rate and population growth rate compared to China.

This suggests that India's population is growing at a faster pace than China's.

Europe:

Country 1: Germany

Birth rate: 8.2 births/1,000 population

Death rate: 11.4 deaths/1,000 population

Population growth rate: -0.16%

Country 2: France

Birth rate: 11.9 births/1,000 population

Death rate: 9.1 deaths/1,000 population

Population growth rate: 0.26%

Statement: In Europe, both Germany and France have lower birth rates compared to the death rates, resulting in a negative population growth rate for Germany and a positive but relatively low growth rate for France. This indicates that both countries are experiencing population decline or slow growth.

France, with a higher birth rate than Germany, manages to maintain a slight population growth.

Africa:

Country 1: Nigeria

Birth rate: 36.6 births/1,000 population

Death rate: 8.2 deaths/1,000 population

Population growth rate: 2.58%

Country 2: South Africa

Birth rate: 20.4 births/1,000 population

Death rate: 9.2 deaths/1,000 population

Population growth rate: 0.93%

Statement: In Africa, both Nigeria and South Africa experience higher birth rates compared to death rates, resulting in positive population growth rates.

Nigeria has a significantly higher birth rate and population growth rate than South Africa, indicating a faster-growing population.

This reflects the overall trend in Africa, where many countries are experiencing high population growth rates due to relatively high birth rates.

Similarities across the regions include the positive population growth rates in most countries, indicating higher birth rates compared to death rates.

However, the magnitude of these rates varies greatly between regions and countries.

Europe generally has lower birth rates, leading to population decline or slow growth, while Asia and Africa have higher birth rates, resulting in faster-growing populations.

Additionally, Africa tends to have higher birth rates and population growth rates compared to Asia.

What is map projection?

Map projection is the term used in cartography to describe a broad set of transformations used to represent the two-dimensional curved surface of a globe on a plane. Coordinates from the surface of the globe are transformed to coordinates on a plane in a map projection, which is often expressed as latitude and longitude.

Some distortions are acceptable depending on the purpose of the map, while others are not. There are various map projections available to preserve some properties of the sphere-like body at the expense of others. The primary goal of studying map projections is to characterise their distortions. There is no limit to the number of map projections that can be created.

Therefore, map projection is a necessary step in creating a two-dimensional map and is one of the essential elements of cartography.
