The cold water is now more dense, due to the added salts, and sinks toward the ocean bottom. Surface water moves in to replace the sinking water, thus creating a current. This deep water moves south, between the continents, past the equator, and down to the ends of Africa and South America.
The biotic pump is a theoretical concept that shows how forests create and control winds coming up from the ocean and in doing so bring water to the forests further inland. This theory could explain the role forests play in the water cycle : trees take up water from the soil and microscopic pores on the leaves release unused water as vapor into ...
The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation. [2] The water cycle involves the exchange of energy, which leads to temperature changes. When water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment.

Eddies of the Agulhas Current meander past the Agulhas Bank leaking warm and salty water into the South Atlantic before retroflecting back into the Indian Ocean Mean chlorophyll-a concentration map of the oceans surrounding Southern Africa for 2009. Note the high productivity water in the Agulhas Retroflection and the very high concentrations ...
Relative isolation of southern Africa by distance from the rest of Africa, global climate changes, rise and fall of sea levels, relative isolation of populations by altitude and life cycle specifics. Local climate changes, drought, flood and fire.
It has been hypothesized that the water is present in the Earth's crust, mantle and even the core and interacts with the surface ocean through the "whole-Earth water cycle". However, the actual amount of water stored in the Earth's interior still remains under debate. An estimated 1.5 to 11 times the amount of water in the oceans may be found ...
The water cycle (or hydrologic cycle or hydrological cycle) is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time. However, the partitioning of the water into the major reservoirs of ice, fresh water, salt water and ...
