Unit 3 Tectonic Plats and Unit 4 Waves Exam Review

Front

What are convection currents?

Back

Convection currents are movements within the Earth's mantle caused by the heat from the core, which creates a cycle of hot magma rising and cool magma sinking, providing energy to move tectonic plates.

Front

What is the role of convection currents in plate tectonics?

Back

Convection currents provide the energy to move the tectonic plates.

Front

What type of boundary occurs when two tectonic plates collide?

Back

Convergent boundary.

Front

What type of boundary occurs when two tectonic plates move apart?

Back

Divergent boundary.

Front

What type of boundary occurs when two tectonic plates slide past each other?

Back

Transform boundary.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave in which the particles of the medium move parallel to the direction of the wave's propagation.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave in which the particles of the medium move perpendicular to the direction of the wave's propagation.

Front

What is the compression of a longitudinal wave?

Back

The compression of a longitudinal wave corresponds to the crest of a transverse wave.

Front

What was Pangea?

Back

Pangea was a supercontinent that existed about 175 million years ago, which eventually broke apart into the continents we know today.

Front

What is the difference between a crest and a trough in waves?

Back

A crest is the highest point of a wave, while a trough is the lowest point.
