Continental Drift

Front

What are tectonic plates?

Back

Tectonic plates are large pieces of the Earth's lithosphere that move and interact with each other, causing geological phenomena such as earthquakes and volcanic activity.

Front

What is the theory of Continental Drift?

Back

The theory of Continental Drift, proposed by Alfred Wegener, suggests that continents were once joined together in a supercontinent called Pangaea and have since drifted apart to their current locations.

Front

What evidence supports the theory of Continental Drift?

Back

Evidence includes similar rock formations on different continents, glacial grooves found in various locations, and fossilized remains of the same organisms on separate continents.

Front

Who proposed the theory of Continental Drift?

Back

Alfred Wegener proposed the theory of Continental Drift.

Front

What is Pangaea?

Back

Pangaea was a supercontinent that existed around 250 million years ago, where all the continents were joined together.

Front

What are glacial grooves?

Back

Glacial grooves are scratches or grooves carved into the Earth's surface by the movement of glaciers, which provide evidence of past glacial activity.

Front

How do tectonic plates move?

Back

Tectonic plates move due to convection currents in the Earth's mantle, which cause them to drift apart, collide, or slide past each other.

Front

What happens when tectonic plates collide?

Back

When tectonic plates collide, they can create mountains, earthquakes, and volcanic activity.

Front

What is the significance of fossil evidence in supporting Continental Drift?

Back

Fossil evidence shows that similar species existed on continents that are now separated by oceans, indicating that these continents were once connected.

Front

What role do earthquakes play in understanding tectonic plates?

Back

Earthquakes occur at the boundaries of tectonic plates, providing evidence of their movement and interaction.
