2. True/False:  The asthenosphere is both hotter and under more pressure than the lithosphere.

Explanation

True! Refer to explanation, paragraph 2.

Submit
3. As you travel deeper into the Earth, the pressure:

Explanation

As you travel deeper into the Earth, the pressure increases. This is because the weight of the overlying rocks and materials creates a force that pushes down on the layers beneath. The deeper you go, the more layers of rock and material there are above, resulting in a greater force and therefore increased pressure.

Submit
4. What is the outermost layer of the Earth called?

Explanation

The outermost layer is the crust. Refer to step 2 to review.

Submit
5. ____________ is a layer of molten metal that surrounds in the inner core.

Explanation

Refer to definitions

Submit
6. This is the most dense layer of the earth:

Explanation

The inner core is the most dense layer of the Earth. It is a solid, iron-rich sphere located at the center of the Earth. The immense pressure at the core causes the iron to be in a solid state, despite its high temperature. The inner core is believed to have a density of about 13 grams per cubic centimeter, making it the densest layer of the Earth. Its high density is due to the compression of the iron atoms under extreme pressure.

Submit
7. The entire core, both outer and inner, are liquid.

Explanation

The core has two parts – a liquid outer core and a solid inner core.

Submit
8. True/False: The mantle is located approximately 200 kilometers beneath the Earth's surface.

Explanation

False: The mantle is located about 40 kilometers beneath Earth's surface.

Submit
9. Where is the lithosphere located on Earth?

Explanation

The lithosphere is located on the crust of the Earth. The lithosphere is the outermost layer of the Earth and is made up of the crust and the uppermost part of the mantle. It is a rigid and solid layer that includes the continents, oceanic crust, and the underlying uppermost part of the mantle. This layer is divided into tectonic plates that float on the semi-fluid asthenosphere below. The lithosphere plays a crucial role in plate tectonics and is where most geological activity occurs, including earthquakes, volcanic eruptions, and the formation of mountains.
