Plate Tectonics

Front

What is Plate Tectonics?

Back

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

Front

What happens at a convergent plate boundary?

Back

At a convergent plate boundary, two tectonic plates move towards each other, often causing one plate to subduct beneath the other, leading to volcanic activity and the formation of mountain ranges.

Front

Define Continental Drift.

Back

The hypothesis that continents were once part of a single landmass (Pangaea) that broke apart and drifted to their current locations.

Front

What is the lithosphere?

Back

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 semi-fluid layer of the mantle beneath the lithosphere, allowing tectonic plates to move.

Front

What is subduction?

Back

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

Front

What are tectonic plates?

Back

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

Front

What is the outer core?

Back

The layer of the Earth located beneath the mantle, composed of molten metal, primarily iron and nickel.

Front

What is the lower mantle?

Back

The solid layer of the Earth located beneath the upper mantle, extending to the outer core.

Front

What is a transform boundary?

Back

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