Layers of Earth & Plate Boundaries

Front

What is the inner core of the Earth?

Back

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

Front

What is the outer core of the Earth?

Back

The outer core is the liquid layer surrounding the inner core, composed mainly of iron and nickel, and is responsible for Earth's magnetic field.

Front

What is the mantle?

Back

The mantle is the thick layer of rock between the Earth's crust and outer core, composed of silicate minerals, and is semi-solid.

Front

What is the crust?

Back

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

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, including the crust and the uppermost part of the mantle, and is broken into tectonic plates.

Front

What is the asthenosphere?

Back

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

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries.

Front

What is a subduction zone?

Back

A subduction zone is a region where one tectonic plate slides beneath another, often leading to volcanic activity.

Front

What are transform boundaries?

Back

Transform boundaries are places where two tectonic plates slide past each other, often causing earthquakes.

Front

What are divergent boundaries?

Back

Divergent boundaries are areas where tectonic plates move apart, leading to the formation of new crust, such as mid-ocean ridges.
