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 are the two main types of tectonic plates?

Back

Oceanic plates and continental plates.

Front

What occurs at a Transform boundary?

Back

Shearing occurs, where two plates slide past each other, often causing earthquakes.

Front

What is a Subduction Zone?

Back

A region where one tectonic plate moves under another, leading to volcanic activity and earthquakes.

Front

What evidence supports the Theory of Plate Tectonics?

Back

Similar fossils found on different continents, the fit of continents, and traces of glacial activity.

Front

What is Seafloor Spreading?

Back

The process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.

Front

What is an Earthquake?

Back

A sudden release of energy in the Earth's crust that creates seismic waves.

Front

What is a Rift Valley?

Back

A lowland region formed by the divergence of tectonic plates, often leading to the formation of new ocean basins.

Front

What happens at a Convergent boundary?

Back

Plates collide, which can cause mountains to form or one plate to be forced under another.

Front

What is the Asthenosphere?

Back

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