Question
Mid-ocean ridges are steeper and less broad than rises because:
Group of answer choices
A) the rocks of the mid-ocean ridges are composed of more dense mineral than the rises.
B) the rocks of the mid-ocean ridges are composed of less dense mineral than the rises.
C) The seafloor spreading rate of ridges are faster than rises causing the oceanic crust to subside closer to the ridge axis.
D) The seafloor spreading rate of ridges are slower than rises causing the oceanic crust to subside closer to the ridge axis.
E) Every ridge is composed of continental crust.
Answer:
The correct answer is D.
Explanation:
In volcanic regions, as the molten magma flows out onto the seafloor creating new beds, the faster it flows, the less steep the mid-ocean ridge is. If however, it is slow-flowing, then oceanic lithosphere formed cool closer to the ridge axis thus making it very steep.

Student Exploration: Building Pangaea Anyone have the answer key to this?
Answer:
Pangea is the name commonly used for the supercontinent, which formed about 300 million years ago and existed in the Paleozoic and Mesozoic before it split into smaller continents about 200 million years ago as a result of plate tectonics. When the continents first merged in Pangea, many mountains were formed, some of which still exist today, such as the Urals or the Antiatlas.
The disintegration of Pangea first gave rise to Gondwana and Laurasia. The further disintegration of Gondwana and Laurasia resulted in the creation of modern continents and islands with a continental crust.

which is the biggest country in the world?
Russia is the largest and widest country in the world. Most people live in cities in the west, near the rest of Europe. Russia is governed from Moscow. It is so big that it has 11 time zones. That means when it is breakfast time in the west, it is late afternoon in the east. Also, it would also take you more than 2 months to cross it if you walked nonstop from west to east.
The principle of fossil succession states that:
a. fossil species found in rock are the same as species living today.
b. every fossil species spans only a limited range of rock layers, corresponding to the time period over which it lived.
c. every rock layer contains only one species of fossil.
d. the same fossil assemblages appear throughout geologic time in a repeating intervals.
Answer:
B. Every fossil species spans only a limited range of rock layers, corresponding to the time period over which it lived
Explanation:
A. Fossil species found in rock are the same as species living today: This is incorrect as the fossil record contradicts that statement.
C. Every rock layer contains only one species of fossil: Example, Ghost Ranch, New Mexico United States. The locality is famous for the Coelophysis quarry which contains the fossils of a Bipedal Triassic dinosaur, the Coelophysis. Other fish fossils were located in the bone bed with the Coelophysis. This contradicts the above claim.
D. The same fossil assemblages appear throughout geologic time in a repeating intervals: Although some rock types do repeat in certain areas they usually don't contain the same fossils unless the rock types repeat in the same group of rock formations in the same time period even than fossils don't always last the whole period. One way of age dating rock formations is worked out by using different fossils and is called Biostratigraphy. This only works because different time periods contain different fossils.

Describe three characteristics that designate the United States as an independent state
Answer:Federalism is an institutional game plan that makes two moderately self-sufficient degrees of government, each having the ability to act legitimately for the benefit of the individuals with the power conceded to it by the national constitution.
Alteration asserts the states' saved forces: "The forces not designated to the United States by the Constitution, nor denied by it to the States, are held to the States individually, or to the individuals." Indeed, state constitutions had bills of rights, which the primary Congress utilized as the hotspot for the initial ten changes to the Constitution.
Equivalent Rights Amendment (ERA), which expects to ensure equivalent rights paying little mind to sex—have fizzled on the grounds that they can't earn adequate assent among individuals from Congress or, on account of the ERA, the states
There are the three in the characteristics that designate the United States as an independent state are:
PopulationFederalismGovernment.What is independent?
The term “independent” refers to freedom from the command, control, or influence of others. Independence is granted unconditionally. The “independence” is most commonly applied to a country, nation, or state, as well as its people, residents, and population. Independence is important in life and for the nation.
According to the three main characteristics are to designate the United States independent are:
Population:- The population are the independent are the United States are the state. Government:- The government is in the making of the decision and the laws are the established. Federalism:- There is an institutional game plan in place that creates two levels of government that are reasonably self-sufficient.As a result, the three main characteristics are the independent are population, federalism, government.

The map above shows where people live in the United States. Areas that are darker blue are areas where people live close
together. Areas that are lighter colors are places where people live farther apart. As a geographer, if you were to study where
people live and why they choose to live in these places, which of the six essential elements of geography would you be
using? Explain your answer in at least three sentences.
Answer:
The Uses of Geography
Explanation:
Out of the six essential elements of geography, I would use The Uses of Geography. I would use it to understand why people are living farther in lighter places and why people living in darker places are living closer. In order to do this, I would have to understand the relationships among people, places, and the environment.
Answer:
If I were studying where people live, I might be using the element of geography called “human systems.” I would be learning about where people live and why they do the things they do. I might also be using the element of geography called “the world in spatial terms.” I would be studying locations, and I would be learning about why things happen in some places but not in others.
6. What weather systems impact Oceania?
Answer:
Warm ocean waters provide the energy to fuel storm systems that provide fresh water vital to all living things. Understanding and predicting precipitation is critical to farmers who decide which crops to plant, and how deep, based in part on soil moisture levels. Crop and food prices may increase when weather that is too wet or too dry adversely affects crops.
Like precipitation, extreme heat and cold also affect livestock management.
Weather prediction can be a life-saving tool. Aside from helping people prepare for catastrophic storms, prediction can help citizens and governments anticipate extreme hot and cold temperatures, which may cause death among the elderly.
Water management experts study how much rainfall to anticipate so they can manage reservoir levels and water usage, to ensure everyone has abundant water supplies.

The images show two different fronts. Item A: A cold front and warm front meet with high level, grey clouds. Item B: Warm air is above cold and very cold air, lower clouds with rain falling. Which fronts are shown?
Answer:
D
Explanation:
Item A shows a stationary front, and item B shows an occluded front.
What is stationary front?A weather front or transition zone between two air masses (cold and warm) is said to be stationary when neither air mass is moving into the other at a ground-surface speed greater than 5 knots.
A warm air mass stuck between two cold air masses creates an occluded front. As the chilly air masses push against one other and collide in the center, the warm air mass rises. As the warm air mass is forced upward and occluded, or "cut off," from the earth, the temperature decreases.
A stationary front is one that is moving very slowly or not at all between warm and cold air masses. An occluded front is a combination of two fronts that develops when a cold front passes over a warm or nearly stationary front.

Deforestation is a major problem in the Amazon Rainforest. Which American state is about the size of the area of the
Amazon that was cleared between 1990 and 2010?
A. Arizona
B. Maine
C. Texas
D. Montana
Please select the best answer from the choices provided

Answer:
The correct answer is D. The state of Montana is about the size of the area of the Amazon that was cleared between 1990 and 2010.
Explanation:
Deforestation is the main problem that threatens the ecological stability of the Amazon jungle, generating through the reduction of forest land contamination, extinction of native species, alteration of ecosystems and many other damages to the environment.
It is calculated that more than 18,000 square kilometers of jungle are cut or burned annually, which, projected over 20 years, gives more than 360,000 square kilometers in which the Amazon jungle has been reduced due to human action. This amount of territory can be compared with the extension of the state of Montana, which has an area that exceeds 380,000 square kilometers.
answer: D
Explanation:
The state of Rondônia in western Brazil — once home to 208,000 square kilometers of forest (about 51.4 million acres), an area slightly smaller than the state of Kansas — has become one of the most deforested parts of the Amazon.
20 percent
That is more than 150 acres lost every minute of every day, and 78 million acres lost every year! More than 20 percent of the Amazon rainforest is already gone, and much more is severely threatened as the destruction continues. It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year.
Threats Facing The Amazon Rainforest
Ranching & Agriculture: Rainforests around the world are continuously cut down to make room for raising crops, particularly soy, and cattle farming. ...
Commercial Fishing: Fish are the main source of food and income for many Amazonian people. ...
Bio-Piracy & Smuggling: ...
Poaching: ...
Damming: ...
Logging: ...
Mining:
The forests are cut down to make way for vast plantations where products such as bananas, palm oil, pineapple, sugar cane, tea and coffee are grown. As with cattle ranching, the soil will not sustain crops for long, and after a few years the farmers have to cut down more rainforest for new plantations.
What changes are occurring to the size of the Amazon rainforest?
Climate change and deforestation could convert the majority of the Amazon rainforest into savanna, with massive impacts on the world's biodiversity and climate.
Deforestation and forest degradation are responsible for around 15% of all greenhouse gas emissions. These greenhouse gas emissions contribute to rising temperatures, changes in patterns of weather and water, and an increased frequency of extreme weather events.
about 100 years
In addition to the carbon release associated with deforestation, NASA has estimated that if deforestation levels proceed, the remaining world's forests will disappear in about 100 years.
