Plate Tectonics

Front

What is Plate Tectonics?

Back

The theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What is the Earth's crust?

Back

The outermost layer of the Earth, which is solid and relatively thin compared to other layers.

Front

What is the mantle?

Back

The thick 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 layer of the Earth beneath the mantle, composed of liquid iron and nickel, responsible for Earth's magnetic field.

Front

What is the inner core?

Back

The innermost layer of the Earth, composed of solid iron and nickel, with extremely high temperatures and pressure.

Front

What is a Divergent Boundary?

Back

A plate boundary where two tectonic plates move away from each other, often resulting in the formation of new crust.

Front

What is a Convergent Boundary?

Back

A plate boundary where two tectonic plates move towards each other, often causing one plate to be forced beneath another.

Front

What is a Transform Boundary?

Back

A plate boundary where two tectonic plates slide past each other horizontally, often causing earthquakes.

Front

What is Subduction?

Back

The process by which one tectonic plate is forced under another plate, leading to volcanic activity and mountain formation.

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact with each other, causing geological activity.
