Which two layers of the Earth are composed of iron and nickel?
Answers
Answer:
The core is made of two layers: the outer core, which borders the mantle, and the inner core. The boundary separating these regions is called the Bullen discontinuity. The outer core, about 2,200 kilometers (1,367 miles) thick, is mostly composed of liquid iron and nickel.

A seismograph station is located several thousand kilometers from an earthquake’s epicenter.
Explain the order that the S and P waves will arrive at the station.
By using the characteristics of the S and P waves explain why they arrive in the order they do.
Answers
Explanation:
At the station, the P-waves arrives first before the S -waves. These two waves are together known as the body-waves. Body waves permeates through the earth unlike the surface waves that moves on the earth surface.
P waves are typically known as the primary waves. They are longitudinal waves as they travel parallel to the source of their propagation. Therefore, they have the highest wave velocity and can travel through any type of medium. By this their longitudinal compressional ability which applies a force in the direction of their propagation, a series of rarefaction and compression occurs along their path and makes them easier to disseminate.
S waves are secondary or shear waves. They are transversal waves because they move perpendicularly to their source. To transmit this kind of wave would be very difficult. Without a body shearing, S - waves cannot propagate. It is therefore, more difficult to transmit the energy in this regard.
The nature of S -waves makes it difficult to be transmitted when compared to P - waves. This will in turn reduce its frequency, and hence its velocity.

Answer:
During a recent congressional hearing, Rick Perry, the US energy secretary, remarked that “to stand up and say that 100% of global warming is because of human activity, I think on its face, is just indefensible”.
However, the science on the human contribution to modern warming is quite clear. Humans emissions and activities have caused around 100% of the warming observed since 1950, according to the Intergovernmental Panel on Climate Change’s (IPCC) fifth assessment report.
Here Carbon Brief examines how each of the major factors affecting the Earth’s climate would influence temperatures in isolation – and how their combined effects almost perfectly predict long-term changes in the global temperature.
Carbon Brief’s analysis finds that:
Since 1850, almost all the long-term warming can be explained by greenhouse gas emissions and other human activities.
If greenhouse gas emissions alone were warming the planet, we would expect to see about a third more warming than has actually occurred. They are offset by cooling from human-produced atmospheric aerosols.
Aerosols are projected to decline significantly by 2100, bringing total warming from all factors closer to warming from greenhouse gases alone.
Natural variability in the Earth’s climate is unlikely to play a major role in long-term warming.
US Energy Secretary Rick Perry stated at a recent congressional hearing that it is "simply absurd" to "stand up and argue that 100% of global warming is because of human activity."
What is global warming?The phenomenon of rising average air temperatures close to the surface of the Earth over the previous one to two centuries is known as global warming.
Since the middle of the 20th century, climate scientists have accumulated extensive data on a variety of weather events and their impacts on the climate.
These findings show that Earth's climate has changed on almost every possible timescale since the beginning of geologic time and that human activities have increasingly affected the pace and scope of current climate change since the beginning of the Industrial Revolution.
Many climate scientists concur that if the global average temperature increased by more than 2 °C (3.6 °F) in such a short period of time, serious societal, economic, and ecological harm would result.
The so-called greenhouse effect, which causes the Earth's surface and lower atmosphere to warm due to the presence of water vapor, carbon dioxide, methane, nitrous oxides, and other greenhouse gases, has grown in intensity, which is the cause of modern global warming.

A problem with the decline in newspapers is dwindling funds for paying trained reporters.
The decline of newspapers serves as both a case study and a tool for understanding and observing how a culture's beliefs change over time. Depending on the area, newspapers may be losing readers. Newspaper closures have been related in studies to losses in civic participation, rises in government waste, and rises in political division.
The decline of newspapers has a number of negative effects, particularly on the local level. The growing "nationalization" of municipal elections has also been related to the decline of local news. Numerous newspapers have reduced their most costly reporting initiatives, including overseas bureaus and investigative journalism, as a result of declining earnings. Investigations might take months, with no guarantee of success.

Answers
A very small population of a species faces a greater threat of extinction than a larger population.
Smaller population faces more random fluctuation, which may result in greater death rate than birth rate and that ultimately leads to their extinction. The greater threat of extinction faced by smaller populations is often a result of genetic drift, which can lead to the loss of genetic variation and the accumulation of deleterious mutations. Genetic drift is more likely to occur in small populations because chance events can have a greater impact on the genetic composition of the population.
Smaller populations also face a greater risk of inbreeding, which can lead to reduced genetic diversity and increased susceptibility to disease and other threats. In addition, smaller populations may be more vulnerable to habitat loss, climate change, and other environmental pressures, which can further reduce their numbers and increase their risk of extinction.
Overall, the small population size can cause a species to be at a greater risk of extinction than the larger population because smaller populations face more random fluctuations that may result in the greater death rate than birth rate.

rivers start to overflow their banks in the ________ flood stage.
Answers
Rivers start to overflow their banks in the "flood stage." The flood stage is a term used to describe the point at which a river's water level exceeds its normal capacity and spills over into the surrounding land. It is a crucial concept in hydrology and river monitoring systems.
The flood stage occurs when the volume of water flowing in a river exceeds its channel's capacity to contain it. This can happen due to heavy rainfall, snowmelt, or a combination of both. When the river reaches the flood stage, it begins to overflow, causing water to spread beyond the riverbanks and inundate the adjacent areas, including floodplains, low-lying regions, and sometimes even urban areas.
The flood stage is an important parameter for predicting and managing floods. It helps in determining the severity of a flood event and enables authorities to issue warnings and take appropriate measures to protect lives and property. River gauges and monitoring stations are used to track water levels and identify when a river is approaching or exceeding its flood stage.
During the flood stage, rivers can cause significant damage and disruption. Floodwaters can erode riverbanks, damage infrastructure such as roads and bridges, and pose risks to human settlements. The impacts of floods can be particularly severe if they occur in densely populated areas or regions with inadequate flood management systems.
In conclusion, the flood stage is the point at which rivers start to overflow their banks, leading to the flooding of surrounding areas. It is a critical stage in river hydrology and plays a crucial role in flood prediction and management. Understanding the flood stage helps in assessing the potential impacts of flooding and implementing appropriate measures to mitigate risks and protect communities.

does anyone have the answers to the unit 5 lesson 10 history unit test on migration and cultural exchange????????
Answers
Answer:
If you search "unit 5 lesson 10 history unit test quizlet" you might get it. Make sure you include the word "Quizlet" at the end.
Explanation:
For this activity, you will be tracking the movement of planets through the sky, much like you did for other celestial objects in Astronomy 1a. One difference in this activity, though, is that you will be measuring how the position of a planet changes relative to a constellation in your view.
Step 1: Choose Your Planet
The planets that will be visible to you depend very much on where you live and what time of year it is. So for this activity, you should do some research to determine which of the following choices of planets will be visible to you: Mercury, Venus, or Mars. For help on which planet(s) are visible when you’re going through this unit, you might consult a site like https://earthsky.org/tonight.
Step 2: Find Your Planet
Sometimes planets can just look like stars in the night sky, so it will be helpful for you to have some more tips on how to find the planet you chose.
Mercury: As viewed from your binoculars, Mercury will appear as a crescent because its orbit is inside of Earth’s.
Venus: As viewed from your binoculars, Venus will also appear as a crescent because its orbit is inside of Earth’s. Venus is usually the brightest object in the night sky (aside from the Moon) so it is best viewed during twilight hours instead of the darker hours of the night, where its glare could make it difficult to focus on.
Mars: Mars will appear red in the sky, especially if you are viewing it through binoculars. It also appears to move quickly through the stars.
After you find your planet, you’ll need to identify a constellation that you can use as a reference point for measuring the planet’s position. Record where the planet is in relation to that constellation, and what time it is.
You will be tracking the movement of the planet for a week. You may want to set up a tracking sheet like this:
TABLE 1 Example
Date Time Location
Step 3: Track Your Planet for a Week
Repeat this process for one week (seven nights of observation). It is okay if you miss a day or two here and there, just make sure you have at least seven entries in your tracking sheet. For example, if you start tracking on Monday but get sick on Tuesday, skip Tuesday and resume on Wednesday. Just make sure your total number of nights tracked is at least seven.
If you use a table like the one in Step 2, then each night note the date in the Date column, the time of your observation in the Time column, and the location of the planet in relation to your constellation of choice in the Location column.
Step 4: Create a Video Presentation Discussing the Movement You Observed
Using a smart phone or other video recorder, create a video of yourself talking through your tracking sheet. Begin with simple descriptions and explanations and then add more details. Your video should be at least 60 seconds long and should cover:
the dates you began and ended observation
the planet and constellation you chose and why you chose each
where the planet first appeared
where it last appeared
how you would describe and explain its movement in between the start and end dates. (For example, sometimes planets move backwards for a few days! Did your planet continue on a straightforward trajectory, or was there something unique about its movement during your tracking period?)
You do not need to add any visuals to your video presentation, unless you feel it will aid in the explanation of your planet’s movement.
To complete this activity, submit your tracking sheet and video file.

in which ways is the carbon in limestone released back into the atmosphere? i. plants leach out the carbon in limestone and consequently release co2 after they are decomposed. ii. geologic processes bring the sediments to the surface, where they are attacked by o2 iii. acid rain dissolves limestone.
Answers
The correct answer is option ii.
The carbon in limestone is released back into the atmosphere through the geologic processes bringing the sediments to the surface, where they are attacked by O2.
In geology, the carbon cycle is a process through which carbon dioxide is repeatedly exchanged between the atmosphere, living organisms, and the hydrosphere to keep its levels sustained and balanced.
Carbon is an essential constituent of nature and is present in living organisms, matter, oceans, and the atmosphere in the form of carbon dioxide.
Furthermore, it is also stored in sediments and rocks under immense temperature and pressure also termed carbon sinks.
Geological processes such as weathering and precipitation decompose the organic matter or sedimentary rocks e.g. limestone as a result of which carbon dioxide is sent back to the atmosphere.
In general, carbon dioxide dissolves in oceans, and ocean water ventilates carbon dioxide back to air.

the reason seawalls exacerbate flooding is because they can trap water that has overwashed.
a. true
b. false
Answers
a. true. A seawall is a structure built along the shoreline to protect coastal areas from the destructive forces of waves and storm surges. While seawalls can provide protection from coastal erosion and flooding, they can also exacerbate flooding in some cases.
This is because seawalls can trap water that has overwashed, preventing it from flowing back into the ocean. As a result, the trapped water can accumulate behind the seawall, increasing the risk of flooding in the area. Therefore, it is important to consider the potential impacts of seawalls on flooding when designing coastal protection measures.
The reason seawalls exacerbate flooding is because they can trap water that has overwashed.
Seawalls can exacerbate flooding because when water overwashes the wall, it can become trapped behind the structure, causing localized flooding. This happens because the seawall may prevent the water from easily flowing back out to sea, leading to increased flooding in the area behind the wall.

Chemical Weathering Exfoliation - is the breakdown of rocks by removal of overburden, a physical process.
Answers
Chemical weathering and exfoliation are two different processes, and exfoliation is a physical process, not a chemical one.
Chemical weathering refers to the breakdown of rocks and minerals through chemical reactions with water, oxygen, acids, and other substances. This process alters the chemical composition and physical properties of the rock, making it more susceptible to other types of weathering.
Exfoliation, on the other hand, is a physical process that involves the gradual removal of layers of rock from a larger formation. This can occur due to changes in temperature, pressure, and erosion. As the overlying layers are removed, the rock underneath may expand and crack, leading to the development of fractures and fissures.
Exfoliation can also occur due to the removal of overburden, which is the soil and rock that cover a particular area. However, this process is still considered a physical process, rather than a chemical one.
