Cars are powered by fossil fuels, which come from the remains of ancient living things that were buried and exposed to high
temperature and pressure from Earth's interior.
Which spheres are represented when fossil fuels form? Check all that apply.
atmosphere
biosphere
O cryosphere
geosphere
hydrosphere

Answers

Answer 1

Fossil fuels form when ancient organism remains from the biosphere are buried under the geosphere and sometimes the hydrosphere, then subjected to heat and pressure, involving the atmosphere in the process.

When fossil fuels form, several of Earth's spheres are represented. The biosphere is involved as it consists of the ancient living things whose remains form the basis of fossil fuels. The geosphere plays a critical role by providing the heat and pressure needed to transform organic matter into fossil fuels. The hydrosphere may be represented if the organic matter was originally deposited in water or if water contributed to the burial and sedimentation of the organic remains. The atmosphere is involved both during the initial growth phase of the organic matter, as plants and other organisms use atmospheric carbon dioxide in photosynthesis, and when the fossil fuels are eventually burned, releasing carbon dioxide back into the atmosphere.

how has the US been involved in the middle East since WWII? ​

Answers

After the World War II ended, the United States have been heavily involved in the Middle East because of its strategic interests.

Explanation:

The Middle East has been of great strategic interests for the United States since the World War II ended. The region had enormous potential, huge reserves of the most demanded resources on the market, the oil, and it was a very fragile region. The United States put in a lot of effort and investment to be sure that they will be the primary player in the region, and in many ways they managed to do so.

The United States have not thought twice when it came to protecting their interests in the Middle East, and that often meant military involvement, ending up in a war. This can be seen in the support for the Afghani people when they fought with the Soviets, with the rapid military intervention when Iraq invaded Kuwait, or with the military intervention in Afghanistan in order to take down the terrorist organization like al-Qaeda and the Taliban.

Geologists study the density of seismic activity in a region by comparing the number of earthquakes to the area of the region. The seismic activity density of a region is found using the formula: seismic activity density = . The state of California covers approximately 103,718 mi2, and has a seismic activity density of 0.0964 earthquakes per square mile. The state of Alaska covers approximately 570,641 mi2, and has a seismic activity density of 0.0491. Using this data and rounding to the nearest whole number, Alaska had more earthquakes than California for the year. Why would the seismic activity density of the year for Alaska be smaller than for California if Alaska had more earthquakes?

Answers

Answer: Alaska has more land area than California

Explanation:

The seismic activity density of a region is the ratio of the number of earthquakes during a given period to the land area:

Seismic activity density = number of earthquakes/land area

If California has 103,718 mi2, and a seismic activity density of 0.0964, then:

density of 0.0964 = number of earthquakes/103,718 mi2

0.0964*103,718 = 9,998 earthquakes

If Alaska has 570,641 mi2, and a seismic activity of 0.0491, then:

density of 0.0491 = number of earthquakes/570,641 mi2

0.0491*570,641 = 28,018 earthquakes

Even though Alaska has a greater amount of earthquakes, California has a greater density, because it has less land.

what are the differences between east and west germany during the cold war

Answers

During the Cold War period, East and West Germany had different developments, with differences occurring in pretty much all aspects.

Explanation:

After the World War II ended, soon started the Cold War. Germany was divided into two parts during this period, West Germany and East Germany. West Germany started to develop in western manner, or rather it became a western democracy, while East Germany was developing in communist manner.

Having these two totally different political ideologies, the two parts of Germany diverged greatly in a period of almost half a century. Some of the differences between the two were:

West Germany was a democracy; East Germany was communist;West Germany had market economy; East Germany had command economy;West Germany allowed freedom of speech, and in general the people enjoyed their rights; East Germany was ruled with iron fist, with the people being oppressed, and having no freedom whatsoever.West Germany industrialized heavily; East Germany was more focused on agriculture;

All of these differences became very evident when the two merged together again. The culture of the people was significantly different. The level of development differed greatly, and it took the country some time to sort itself out. Even after three decades from the end of the Cold War, the differences are still easy to see between the West and the East of the country.

what is the US policy towards refugees from Haiti? Why do you think it differs from U.S policy toward Cuban refugees?​

Answers

Answer:

The US government's policy towards Haitian refugees is to treat them as economic refugees. The US government's policy towards Cuban refugees is to treat them as political refugees.

Explanation:

Haitian refugees:

Haiti is the poorest country in the Western Hemisphere, with a per capita income of about $100 per year. The U.S. government classifies Haitians as "economic" and not "political" refugees. This makes it easier to deport them. The US government has also traditionally been supportive of repressive regimes in Haiti, like Duvalier and his son who were longterm leaders like a family dynasty in Haiti. Another figure of Haitian politics who has sometimes been in favor of the US government, and at times in disfavor is Jean-Bertrand Aristide. It is alleged that the USA orchestrated two coup attempts again Aristide in 1991 and then his forced exile in 2004. The USA plays a more active role in Haitian politics and who assumes power than it does in Cuba.  In 2015, there were reportedly 676,000 Haitian migrants in the United States.

Cuban refugees:

In contrast, Cuban refugees are considered political refugees and the US government does not support the Castro regime nor his brother who was also the President of Cuba after Fidel's death (the President is now Miguel Díaz-Canel).  There is also a substantial and powerful Cuban-American population, especially in the state of Florida. The majority of the 1,172,899 current Cuban exiles living in the United States live in Florida. They can influence politics in the state and also at the federal level because of their power as a community. Most Cuban-Americans are anti-Castro and thus they support the embargo against Cuba.

Answer:

The statement is false. In the Southeastern United States, the African American community is the biggest of the nation, but it doesn't reach half of the nation's African Americans.

Explanation:

Southeastern United States is formed by the states of Alabama, Florida, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, Virginia and West Virginia.

Approximately 15% of the American population, that is, about 50 million inhabitants, belong to the African-American ethnic group. These 50 million are distributed throughout the country, but they are specifically concentrated in these states: in Alabama there are about 2 million, in Florida 3 million, in Georgia 3.5 million, in Mississippi 1.2 million, in Tennessee 1.3 million, in North Carolina 2.5 million, in Kentucky 350,000, in South Carolina 1.5 million, in Virginia 2 million and in West Virginia 100,000. The sum of these numbers gives an approximate total of 17,500,000 African Americans living in this region, which does not make up 50% of the nation's total, but 35% of the total number of African Americans.

Hello:) I really need help with transform plate boundaries. I’ve read the examples in my textbook but it’s still confusing for me. Anyone able to help ? Thanks ☺️

Answers

In Plate Tectonic Theory, the lithosphere is broken into tectonic plates, which undergo some large scale motions. The boundary regions between plates are aptly called plate boundaries. Based upon their motions with respect to one another, these plate boundaries are of three kinds: divergent, convergent, and transform.
Transform plate boundaries are places where plates slide sideways past each other. At these boundaries lithosphere is neither created or destroyed. Many transform boundaries are found on the sea floor, where they connects bits and pieces of diverging mid-ocean ridges. For example, California’s SAN Andreas fault is a transform boundary. Another example is the Alpine Fault of New Zealand. Transform Boundaries can also cause earthquakes, split river beds and linear valleys. They can even cause tsunamis which is sometimes caused by movement of the ocean due to earthquakes.

if its 12 noon at greenwich
what us the time at 16 degrees west​

Answers

Answer:

[tex]10: 56 \text { is the time at } 16^{\circ} \text { west. }[/tex]

Explanation:

The time is 12:00 noon in “Greenwich” by using Greenwich Mean Time (GMT) we can calculate the time in your present location. From the question we know that present location is 16° west.

If we are in west of the “Greenwich median” we need to “subtract” the time from actual Greenwich Mean Time (GMT) your time is ahead. If we are in the east of the “Greenwich median” we need to “add” the time from actual Greenwich Mean Time (GMT) your time will be “after”.

To find the time at 16° west:

We know that 1° = 4 minutes, present location is 16° west then 16 × 4 = 64 minutes = 1 hour 4 minutes. We need to subtract 1 hour 4 minutes from actual time 12:00 noon it becomes 10:56.

Explanation:

The mountains are one of the basic physical geographic forms. They are also one of the most common major physical features in the world. The mountains are a product of the tectonic activity, though there are several different ways in which they are formed.

The mountains are not found everywhere though, and they are much more concentrated in some areas, and absent or isolated in other areas. In general, the younger mountains are found close to the active boundaries of the tectonic plates, while the older mountains are found further away from tectonic boundaries, or rather at places where there were tectonic boundaries in the past. Some facts about the mountains are:

They can form because of horizontal or vertical pressureThe volcanoes too create mountainsThe mountains can not alleviate forever, as their weight and the erosion don't allow it after a particular heightThe highest mountain chain in the world is formed at a continental-continental convergent boundaryThe mountains are lacking or are very rare in the interior of the continents, or rather in the central parts of the tectonic plates They can be found on all continents

Explanation:

Most nuclear reactors use fission to produce nuclear energy. This means larger mass atoms decompose into light atoms while releasing energy in the process. In the process radiation such as  beta or alpha particles can be produced. The particles and radiation have an ionizing effect and mean they can destroy DNA hence resulting in the mutation of living organisms. Most mutations are lethal and result in death of the organism. This is the reason it is dangerous to be close to nuclear plants in case of a disaster that results in leakage of radioactive material into the environment.

which is the largest sphere of earth? geosphere, hydrosphere, cryosphere, biosphere, or atmosphere?

Answers

the answer is biosphere

Final answer:

The largest sphere of Earth is the geosphere or lithosphere. It contains the entire solid body of the planet, including rocks and minerals, and holds vastly more carbon than other spheres, indicating its larger mass.

Explanation:

The Earth is made up of several interconnected spheres, including the atmosphere, hydrosphere, lithosphere (or geosphere), biosphere, and cryosphere. When considering which is the largest, we can look to various measurements, such as mass or volume. Based on these considerations, the geosphere or lithosphere, which encompasses the entire solid body of Earth, including its rocks and minerals, is the largest sphere.

In terms of the total amount of carbon, which can be used as a proxy for mass, the lithosphere contains significantly more than the other spheres. To illustrate, here is the total amount of carbon in each sphere:

Biosphere: 605 billion tons

Atmosphere: 760 billion tons

Hydrosphere: 39,000 billion tons

Lithosphere: 40,005,600 billion tons

Answer:

It is difficult to forward a single and uniform meaning of the term geography because geography as a science is extremely broad, encompassing multiplicity of concepts and areas of study.

Geography is a science that aims to study the Earth's surface and the spatial distribution of significant phenomena in the landscape. It also studies the reciprocal relationship between man and the environment (Human Geography). One of the central themes of geography is the relationship between man and nature. Nature is understood as the forces that generated or contribute to shape the geographic space, that is, the dynamics and interactions that exist between the atmosphere, lithosphere, hydrosphere and biosphere. Man is understood as an organism capable of considerably modifying the forces of nature through technology.

The way with which the United States rule is with the trade policies of the country towards the other countries or the strong financial position of the country.    

Answer:

The leadership role of the United States in the post Cold War, post industrial world is known as the New World Order.

Explanation:

With the fall of the Soviet Union in 1991 and the end of the Cold War, the bipolar world that had been standing since the end of World War II ended: a capitalist world and a communist one.

From that year on, capitalism took control of most of the nations of the world, with the exception of a few countries, generally authoritarian. This made the United States the only visible superpower capable of influencing international policy with its decisions. Thus, organizations such as the UN, NATO and even smaller regional organizations saw their policies influenced directly or indirectly by American interests.

The United States began to take a much more participatory role as an intermediary in international conflicts, and to guide the destinies of the world economy, being the main investor in the different countries around the world.

It is only in the 2010s that this situation started to change, with the advent of China as a political and economic power capable of challenging American power.
