Plate Tectonics

Front

What is Plate Tectonics?

Back

The theory that explains the movement of the Earth's plates and how they interact with each other.

Front

What are the three main types of plate boundaries?

Back

Divergent, Convergent, and Transform boundaries.

Front

What happens at a Divergent boundary?

Back

Plates move apart, creating new crust as magma rises to the surface.

Front

What happens at a Convergent boundary?

Back

Plates collide, which can cause one plate to subduct beneath another, leading to earthquakes and volcanic activity.

Front

What is a Transform boundary?

Back

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

Front

What is subduction?

Back

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

Front

What type of crust is typically involved in subduction zones?

Back

Oceanic crust is usually subducted beneath continental crust.

Front

What geological feature is commonly formed at Convergent boundaries?

Back

Mountains can be formed when two continental plates collide.

Front

What is continental drift?

Back

The theory that continents have moved over geological time and were once joined together.

Front

What evidence supports the theory of continental drift?

Back

Similar fossils found on different continents and the fit of continental coastlines.
