Label the parts of the transverse wave.

Amplitude:

Crest :

Trough:

Wavelength:

A transverse wave occillates perpenticular to the direction of energy transfer. A = Crest, B = trough, C = Amplitude, and D =  Wavelength.

Transverse Wave,

In this wave oscillates perpendicular to the energy transfer. For example, Electromagnetic wave.

Therefore, A = Crest, B = trough, C = Amplitude, and D =  Wavelength.

Amplitude: B

Crest: A

Trough: C:

Wavelength: D

Explanation:

The amplitude of the wave is defined as the distance from the equilibrium position of the wave to its crest or troughs; therefore,

Amplitude: B

The Crest of a wave is its highest point from its equilibrium position; therefore,

Crest: A

The trough of a wave is its lowest point measured from equilibrium position; therefore,

Trough: C

The wavelength of a wave is the distance between two identical points on a wave; therefore,

Wavelength: D.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
