Question

A disturbance sends ripples across water in a tub.

What are these ripples called?


surface waves

longitudinal waves

rarefactions

compressions

Answer 1

I believe it is surface waves because it happens at the surface of the water.

Answer 2

Option (1)

Step-by-step explanation:

Ripples (ripple marks) are formed due to the forward and backward motion of water over the surface of a rock bed or water bodies. They are usually formed when the flow velocity is less and the diameter of the grains is relatively small.

These are sedimentary structures that are found in many places. These ripples are divided into 2 types, namely the symmetric and the asymmetric ripples. Asymmetrical ripples are helpful in identifying the palaeocurrent direction.

These are formed when water travels over the surface, so it can be considered as the surface waves.

Hence, the most appropriate answer is option (1).
