Study the table about Earth’s interior.

A 4 column table with 5 rows. First column is unlabeled with entries: Crust, uppercase mantle, Lower mantle, Outer core, Inner core. Second column is labeled Thickness in kilometers with entries: 30, 720, 2,171, 2,259, 1,221. Third column is labeled Density in grams per centimeters cubed, divided into Top and Bottom columns. Top entries are: 2.2, 3.4, 4.4, 9.9, 12.8. Bottom entries are 2.9, 4.4, 5.6, 12.2, 13.1. Fourth column is labeled Types of Rock Found with entries: Silicic rocks, Peridotite, Magnesium and silicon oxides, Iron plus oxygen, Iron plus oxygen.

Which conclusion is supported by information in the table?

The mantle is thinner than the crust.
The core is the thickest of Earth’s layers.
The inner core is thicker than the outer core.
The mantle is the thinnest of Earth’s layers.

A student at an exhibition looks at a model of Earth, as shown. The model is made using different colors to show water and land on the surface of Earth. The color green shows areas covered in land and blue shows areas covered in water. Each side of the model is shown.



The student learns that the water on Earth is stored in different forms. Water on Earth is broadly categorized into salt water and freshwater. The usability of water depends on the quantity available and its characteristics. The model shows the distribution of water on Earth in various reservoirs.

Question:The student claims there are large quantities of water immediately available for humans to drink on the surface of Earth. Is the claim given by the student correct? Use evidence from the graphs to describe why or why not.

Researchers have been studying how emissions from both volcanoes and human activities, such as the burning of fossil fuels, impact the atmosphere. Both types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.

Explain why the total mass of carbon must be decreasing in a different step of the slow carbon cycle based on the on the increase in atmospheric CO2.

The water cycle is also called the Hydrolic Cycle.
It is the process by which water circulates between Earth’s oceans, atmosphere, and land.
It involves the following:
Water storage
evaporation
transpiration
