Answer :First part is what you learned so write what you learned then the other parts is The evidence that the universe is expanding comes with something called the red shift of light.

Explanation:
The answer is c) electromagnetic sawed in which the vibrations are perpendicular to the motion of the sound
The best answer is D.
Stress is a force that acts on rock to change its shape or volume. Because stress is a force, it adds energy to the rock, which is stored in the rock until either the rock breaks or changes shape.
There are three kinds of stress, namely shearing, tension and compression.
Shearing- force that pushes a mass of rock in two opposite directions and can cause rock to break and slip apart or change shape.
Tension - force that pulls on the crust, stretching rock so that it becomes thinner in the middle.
Compression - force that squeezes rock until it folds or breaks
