Answer:

Doppler effect refers to apparent change in frequency/wavelength of the source due to the relative motion between the source and the observer. The frequency increases apparently if the source and observer approach each other and it decreases apparently if the source and the observer move away from each other.

When, apparent frequency increases, it is known as blue-shift and if it decreases, it is known as red-shift.

What best describes desert pavements

Gekata [30.6K]

Answer:

Explanation:

A common theory suggests that desert pavements are formed through gradual removal of sand and other fine particles by the wind and intermittent rains leaving behind the large fragments. The larger rock particles are shaken into place by actions of different agents such as rain, wind, gravity, and animals
