Earth's Layers

Front

What is the lithosphere?

Back

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

Front

What layers make up the lithosphere?

Back

The lithosphere is made up of the crust and the upper mantle.

Front

What is the mantle?

Back

The mantle is the layer of the Earth located between the crust and the outer core, composed of semi-solid rock that flows slowly.

Front

What is the outer core?

Back

The outer core is the liquid layer of the Earth's core, located beneath the mantle and above the inner core, primarily made of iron and nickel.

Front

What is the inner core?

Back

The inner core is the solid, innermost layer of the Earth, composed mainly of iron and nickel, and is extremely hot.

Front

What is the difference between the inner core and outer core?

Back

The inner core is solid due to immense pressure, while the outer core is liquid.

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer of the mantle that lies beneath the lithosphere and allows tectonic plates to move.

Front

What is the mesosphere?

Back

The mesosphere is the lower part of the mantle, located beneath the asthenosphere, where the rock is more rigid.

Front

How do tectonic plates interact at the lithosphere?

Back

Tectonic plates interact at the lithosphere by moving apart, colliding, or sliding past each other, leading to geological events.

Front

What is the role of the mantle in Earth's geology?

Back

The mantle plays a crucial role in Earth's geology by facilitating the movement of tectonic plates and recycling materials.
