Practice Flashcard - ELL Earth Layers

Front

What happens to pressure as you go deeper into the Earth?

Back

Pressure increases as you go deeper into the Earth.

Front

What happens to temperature as you go deeper into the Earth?

Back

Temperature increases as you go deeper into the Earth.

Front

Which layer of the Earth is the least dense?

Back

The crust is the least dense layer of the Earth.

Front

Which layer of the Earth is denser: the lithosphere or the asthenosphere?

Back

The asthenosphere is denser than the lithosphere.

Front

What are the main components of Earth's core?

Back

The core is primarily made up of iron and nickel.

Front

If an object is more dense than the fluid it is in, what will it do?

Back

It will sink.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer beneath the lithosphere that allows for tectonic plate movement.

Front

What is the relationship between density and buoyancy?

Back

Objects with higher density than the fluid they are in will sink, while those with lower density will float.

Front

What is the composition of the Earth's crust?

Back

The Earth's crust is primarily composed of rocks and minerals, including silicates.
