Convection, Pangea, and Continental Drift

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 Pangea?

Back

Pangea was a supercontinent that existed about 335 million years ago, where all the continents were joined together before they drifted apart.

Front

What is Continental Drift?

Back

Continental Drift is the theory that continents have moved over geological time and were once part of a single landmass.

Front

Where is the Ring of Fire located?

Back

The Ring of Fire is located around the edges of the Pacific Ocean, known for its high volcanic and seismic activity.

Front

What direction do Divergent plates move?

Back

Divergent plates move away from each other.

Front

What is a Convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, often causing one plate to be forced beneath the other.

Front

What is a Transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally.

Front

What evidence supports Alfred Wegener's Theory of Continental Drift?

Back

Evidence includes similar fossils found on different continents, matching geological formations, and climate evidence such as glacial deposits.

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 role of convection currents in the Earth's mantle?

Back

Convection currents in the mantle drive the movement of tectonic plates, causing continental drift and volcanic activity.
