Earth's Layers Mini Flashcard

Front

What is the inner core of the Earth?

Back

The inner core is the innermost layer of the Earth, composed primarily of iron and nickel, and is solid due to the immense pressure.

Front

What is the lithosphere?

Back

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

Front

What is the asthenosphere?

Back

The asthenosphere is a semi-fluid layer of the mantle located beneath the lithosphere, allowing for the movement of tectonic plates.

Front

What is the crust?

Back

The crust is the outermost layer of the Earth, composed of solid rock, and is where we live.

Front

What is the outer core?

Back

The outer core is a liquid layer composed mainly of iron and nickel, located beneath the mantle and surrounding the inner core.

Front

What are the main layers of the Earth?

Back

The main layers of the Earth are the crust, mantle, outer core, and inner core.

Front

How does the temperature change as you go deeper into the Earth?

Back

The temperature generally increases with depth due to the heat from the Earth's core and radioactive decay.

Front

What is the difference between the lithosphere and the asthenosphere?

Back

The lithosphere is rigid and includes the crust and upper mantle, while the asthenosphere is semi-fluid and allows for tectonic movement.

Front

What materials primarily make up the Earth's inner core?

Back

The inner core is primarily composed of solid iron and nickel.

Front

What role does the outer core play in Earth's magnetic field?

Back

The movement of liquid iron in the outer core generates Earth's magnetic field through the dynamo effect.
