The number one way to prevent water pollution is to not dump waste materials into bodies of water. You can also clean street trash to prevent it from blowing into the waters.
The thermosphere is the first layer of the atmosphere where there are enough heavier molecules (oxygen) to absorb a significant anount of the Sun's radiation. Below the thermosphere, much of the heat is dissipated by convective currents.
Although technically "hot", the gas in the thermosphere is so thin that it can pass little heat to other molecules, and loss of heat by radiation would still cool objects in this part of the atmosphere.
the sun's radiation strikes it first
As waves approach the shore, interaction with the sea floor slows the waves down and the crests of the waves bunch up. They increase in height as the energy in each wave compresses into a shorter horizontal distance, but the period of the wave does not change. Eventually, the waves break.

watershed
The alluvial silt that covers the land during flooding increases its fertility. This is in addition to the ready supply of fresh water required for any large societal group.
Marsh
A swamp is a wetland that has trees and brushes.
As water is cooled its density increases until it reaches about 4 C and then it decreases.
