Answer:

basalt and a layer of salt sediment

Explanation:

Oceanic crust, extending 5-10 kilometers (3-6 kilometers) beneath the ocean floor, is mostly composed of different types of basalts. Geologists often refer to the rocks of the oceanic crust as “sima.” Sima stands for silicate and magnesium, the most abundant minerals in oceanic crust.

Explanation:

Item A shows a stationary front, and item B shows an occluded 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.

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.  

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.

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.

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."

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.
