Unit 3 and 4 Exam Review

Front

What is the lithosphere?

Back

The lithosphere is the outermost mechanical layer of the Earth, known for being brittle and rigid. It includes the crust and the uppermost part of the mantle.

Front

What must be changed to alter the speed of a wave?

Back

To change the speed of a wave, you must change the medium through which it travels.

Front

What type of plate boundary occurs when two plates collide?

Back

A convergent plate boundary occurs when two tectonic plates collide.

Front

What is a true statement about waves?

Back

Waves transfer energy without transferring matter.

Front

In a longitudinal wave, how are the vibrations oriented in relation to the direction of energy transfer?

Back

The vibrations in a longitudinal wave are parallel to the direction of energy transfer.

Front

What is the definition of a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is the difference between a convergent and divergent plate boundary?

Back

A convergent plate boundary occurs where two plates collide, while a divergent plate boundary occurs where two plates move apart.

Front

What is the role of the asthenosphere?

Back

The asthenosphere is a semi-fluid layer beneath the lithosphere that allows tectonic plates to move.

Front

What happens to wave speed when it travels from air to water?

Back

The speed of the wave increases when it travels from air to water due to the denser medium.

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the energy of the wave.
