Question and answer
Are tropical grasslands called steppes found in the tropical wet-and-dry climate region. $*** DJ***$
TROPICAL GRASSLANDS (SAVANNAH) Location; · Mainly between latitudes 5° and 15° north and south of the Equator. · Interior of continents, e.g. [ the Llanos (Venezuela), the Campos (Brazilian Highlands), most of Central Africa surrounding the Congo Basin, parts of Mexico and northern Australia. Climate: · Climatically determined savannahs (African) develop in regions with marked
wet and dry seasons · Rainfall ranges between 100 and 400 mm a year. · Variation in vegetation according to rainfall; a) When the rainfall is 100-200 mm, generally only grasses can survive the dry season. b) When the rainfall reaches 300 mm the soil retains enough water to sustain shrubs through the dry season as well. c) When the rainfall exceeds 300 mm, enough water is left to support solitary trees. d) When rainfall exceeds 400 mm, enough moisture remains during the dry season to allow trees to grow and form a canopy, which shades out the grasses. · In regions of higher rainfall (East Africa), savannah vegetation is maintained by periodic fires. · Fires consume dry grass at the end of the wet season, burn back forest vegetation, check tree/shrub growth and stimulate new grass growth. · Savannahs are also influenced by large grazing mammals, e.g. wildebeest/zebra. · Animals reduce vegetation so that the grassy cover cannot carry a fire. · Woody vegetation increases as a result, to be controlled by large browsers, e.g. elephants · Temperatures remain high throughout the year, but there is a slightly cooler season when the sun in overhead the tropic in the opposite hemisphere. · Annual range is also slightly greater (8°C in Kano) due to the sun’s slightly reduced angle in the sky for part of the year, distance from the sea and less complete cloud and vegetation cover. · Temperature may drop slightly at the start of the rainy season. ]
