Continental Drift & Plate Tectonics

Front

What is Continental Drift?

Back

The theory that continents have moved over geological time and were once joined together in a single landmass.

Front

What are Plate Tectonics?

Back

The scientific theory that explains the movement of the Earth's plates and how they interact at their boundaries.

Front

What is a Transform Boundary?

Back

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

Front

What is a Convergent Boundary?

Back

A plate boundary where two plates move towards each other, often causing one plate to be forced below the other.

Front

What is a Divergent Boundary?

Back

A plate boundary where two plates move away from each other, leading to the formation of new crust.

Front

What is a Subduction Zone?

Back

An area where one tectonic plate is being pushed under another, often leading to volcanic activity.

Front

What happens at the Mid-Atlantic Ridge?

Back

It is a divergent boundary where new oceanic crust is formed as tectonic plates move apart.

Front

What is the Ring of Fire?

Back

A major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur.

Front

What is the significance of the San Andreas Fault?

Back

It is a transform boundary that is known for its seismic activity and earthquakes.

Front

What type of boundary is formed when an oceanic plate collides with a continental plate?

Back

A convergent oceanic-continental boundary.
