Continental Drift and Plate Tectonics Review

Front

What is convection?

Back

Convection is the process of heat transfer in fluids (liquids and gases) where warmer, less dense areas rise and cooler, denser areas sink, creating a circular motion.

Front

What is a subduction zone?

Back

A subduction zone is a region where one tectonic plate sinks below another, often leading to volcanic activity and the formation of mountain ranges.

Front

What distinguishes a supervolcano from a regular volcano?

Back

Supervolcanoes are more powerful and erupt less often compared to regular volcanoes.

Front

How do the Hawaiian islands form?

Back

The Hawaiian islands formed at a hotspot, where magma from deep within the Earth rises to create volcanic islands.

Front

What is formed whenever a subduction zone is created?

Back

A volcano is formed whenever a subduction zone is created.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries, causing geological activity.

Front

What is the theory of continental drift?

Back

The theory of continental drift suggests that continents were once joined together and have since drifted apart over geological time.

Front

What is a rift valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates, often characterized by steep walls and a central block.

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is thinner and denser than continental crust, which is thicker and less dense.

Front

What is a transform boundary?

Back

A transform boundary is a type of tectonic plate boundary where two plates slide past each other horizontally.
