Continental Drift vs Plate Tectonic Theory

Front

What is the Continental Drift Theory?

Back

The theory that all continents were once joined together as a single landmass and have since drifted apart over millions of years.

Front

What does the Theory of Plate Tectonics explain?

Back

It explains the movement of the Earth's plates and how they interact at their boundaries, leading to geological phenomena.

Front

What is a transform boundary?

Back

A type of plate boundary where two plates slide past each other, causing earthquakes, like the San Andreas Fault.

Front

What is a convergent boundary?

Back

A boundary where two tectonic plates collide, often leading to mountain formation or subduction.

Front

What is a divergent boundary?

Back

A boundary where two tectonic plates move apart, allowing magma to rise and create new crust.

Front

What is subduction?

Back

The process where one tectonic plate moves under another, often leading to volcanic activity.

Front

Who proposed the Continental Drift Theory?

Back

Alfred Wegener.

Front

Was the Continental Drift Theory accepted during Wegener's lifetime?

Back

No, it was largely rejected by the scientific community at that time.

Front

What geological feature is formed at divergent boundaries?

Back

Mid-ocean ridges, where new oceanic crust is created.

Front

What is the significance of the San Andreas Fault?

Back

It is a major transform fault that marks the boundary between the Pacific and North American plates.
