☆☆☆☆☆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

Conductivity can be used to calculate the salinity of the water.
The epipelagic ocean zone is most habitable.
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.
