WebRadiant energy from the sun that falls on the oceans is absorbed in the “mixed-layer” of seawater, 50–100 m thick, at the surface, forming a reservoir of warm water near the equator that stays at 26–31 °C day and night year round. Below the mixed layer the water temperature falls gradually with depth, reaching a temperature of about 4 °C. at … WebThe earth-atmosphere energy balance is achieved as the energy received from the Sun balances the energy lost by the Earth back into space. In this way, the Earth maintains a stable average temperature …
