Four Ecological Cycles

There are likewise geological components to the carbon cycle as carbon ignore be produced by volcanoes (Remer, 2009).

Most of the earth's peeing is found in the oceans, polar ice, and free-base water supply; this restricts the access for most plants and animals, with humans being the study exception because humans can access water from totally three sources. Water flux occurs through evapotranspiration, precipitation, and runoff. The sun heats water in the oceans, which evaporates into the atmosphere. Evapotranpiration includes evaporation from oceans as well as water vapor that evaporates from ice and reverse, plus water that evaporates from soil. Evapotranpiration also includes transpiration from plants. insurrection air currents lift the evapotranspired water vapor higher, where cooler temperatures outcome in condensation into clouds. The clouds produce precipitation, which returns water to the earth as rain or snow and their variants.

Frozen water may be stored for thousands of years in

glaciers or snow packs; other frozen water and precipitation becomes runoff into rivers, lakes, oceans, and the ground as infiltration, sometimes collecting in aquifers underground (Perlman, 2008).
