The magnitude of the change in AGB is influenced by soil clay fraction: The mean (solid line), 1σ deviation (shaded region), and minimum and maximum values (dashed lines) are shown. And where there is a shortage of soils, vegetation is not seen, e.g., in the polar areas.

Climate, soil, the ability of soil to hold water, and the slope, or angle, of the land all determine what types of plants will grow in a particular region. Natural Environment and Human Response of the Equatorial Region. Soil slopes, relief, and soil depth: Steep slopes in mountain and hilly regions causes soils to be eroded quickly by rainfall unless soils are covered by throughout the year by crops or forest.

In Malaysia and Indonesia rainforests cover large section of the countries, whereas in southern Sri Lanka and Java they have almost entirely replaced by agricultural landscapes where plantations of tea, coconut palms, and rubber trees cover the Mountain slopes and hills. Previous studies suggest that the ice table (the uppermost occurrence of ice in the regolith) would continuously recede throughout geologic history. The Mungo River and its tributaries represent the major sources of water supply for agriculture and drinking purposes for the Douala city and the south western agricultural region of Cameroon. However, in a rainforest, there is a continuous supply of leaves, animal droppings and other organic matter which are quickly broken down with the help of decomposers and incorporated into the topsoil.
