Plate Tectonics Review

Front

What happens at convergent boundaries?

Back

At convergent boundaries, tectonic plates collide, and the denser plate is forced beneath the less dense plate, a process known as subduction.

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 and have since drifted apart.

Front

What evidence supports Wegener's theory?

Back

Evidence includes matching coal fields between North America and Europe, tropical fossils found in the Arctic, and glacier tracks in South Africa.

Front

How do tectonic plates move at divergent boundaries?

Back

At divergent boundaries, tectonic plates move away from each other, creating new crust as magma rises to the surface.

Front

What type of heat transfer occurs in a microwave?

Back

Microwaves use radiation to heat food, transferring energy through electromagnetic waves.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases), where warmer areas rise and cooler areas sink.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, which can occur in a vacuum.

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 subduction?

Back

Subduction is the process where one tectonic plate is forced beneath another, often leading to volcanic activity.
