Layers of the Earth and Plate Tectonics

Front

What is a transform boundary?

Back

A transform boundary is a type of tectonic plate boundary where two plates slide past each other horizontally.

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move toward each other, often resulting in one plate being forced beneath the other.

Front

Who proposed the hypothesis of Continental Drift?

Back

Alfred Wegener proposed the hypothesis of Continental Drift.

Front

What process is responsible for building new oceanic crust?

Back

Sea floor spreading is the process that builds new oceanic crust.

Front

What layer of the Earth is located above the outer core?

Back

The mantle is the layer of the Earth located above the outer core.

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 the semi-fluid layer of the mantle beneath the lithosphere, allowing for the movement of tectonic plates.

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another plate and sinks into the mantle.

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 the theory of plate tectonics?

Back

The theory of plate tectonics explains the movement of the Earth's plates and how they interact, leading to geological phenomena such as earthquakes and volcanic activity.
