Chemical processes and physical processes are how water is cycled from land to the atmosphere.
I don’t think I understand the question but true?
Potential energy is the answer
Mechanical
waves are oscillation of matter, they are important because they all
transfer energy from one place to another. There are 2 types of
mechanical waves. A transverse wave where the particles vibrate
perpendicular to the direction of energy travel and a longitudinal
wave where particle vibrations are parallel to the direction of the
energy transfer.

hope it helps, Regards.
