Tropical grasslands (Savanna) Climate There are two main seasons in the African savanna- winter‚ or the “dry season”‚ and summer‚ also known as the “wet season”. They are called dry and wet according to the amount of precipitation each season receives. Most of the annual precipitation in the savanna occurs during summer (approx. April to October)‚ while during the winter (approx. November to March) there is almost no rain at all. The annual precipitation is

physical causes are rising temperatures‚ falling rainfall‚ wind‚ flash floods and topography. Soil degradation has many consequences on environment and populations. These consequences can occur in a short time period with little warning. These consequences can be both local or beyond the locality and most likely global. Desertification is the most serious consequence of soil degradation. Desertification is the gradual transformation of habitable land into desert. It is caused by climate change and improper

a wall‚ or the planting of trees to keep the soil in place with the roots of the tree. Other ways to avoid erosion are terracing‚ mulching‚ land leveling‚ or conservation tillage. D) One biome that is rich in humus is grassland soil. Humus originated in it because it is semiarid climate and little rainfall is seen in the grassland creating less leeching than most soil types. This creates a large buildup of organic material and humus. Another way Humus originates in grassland is due to the grasses

Peru has a complex geography dominated by the high and rugged Andes and the Pacific currents‚ which create climates and landscapes as widely varied as the desert coast‚ the highlands of Andes‚ and the Amazon rainforest. Peru is one of the most bio-diverse countries in the world and contains a wealth of major extractive resources. The modern Peruvian culture is a result of initial interbreeding between the

is strongly influenced by the Himalayas and the Thar Desert. The Himalayas‚ along with the Hindu Kush mountains in Pakistan‚ prevent cold Central Asian katabatic winds from blowing in‚ keeping the bulk of the Indian subcontinent warmer than most locations at similar latitudes. Concurrently‚ the Thar Desert plays a role in attracting moisture-laden southwest summer monsoon winds that‚ between June and October‚ provide the MOST of India’s rainfall. At the moment‚ India’s climate is governed by the

contrast to areas with savannaclimates and monsoon regimes‚mediterranean climates have wet winters and dry summers.Tropical rainforests technically do not have dry or wet seasons‚ since their rainfall is equally distributed throughout the year. Some areas with pronounced rainy seasons will see a break in rainfall mid-season‚ when the intertropical convergence zone or monsoon trough moves poleward of their location during the middle of the warm season. When the wet season occurs during a warm season
