WORLD HISTORY

Detailed explanation-1: -A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.

Detailed explanation-2: -Savannas are open grassy landscapes with few trees scattered throughout the land. Grasslands are also dominated by grass; however, the climate does not support woody trees. Ecologists subdivide savanna into three categories – wet, dry, and thornbush. The classification is based on the length of the dry season.

Detailed explanation-3: -savannah. For the noun referring to a flat grassland in a tropical or subtropical region, savanna is the usual spelling in American English, while savannah is preferred in all the other main varieties of English.

Detailed explanation-4: -Savannas are the tropical version of the temperate grasslands. Most savannas are caused by climatic patterns where there is a strong dry season for a large part of the year. Few trees survive in these regions, but most savannas do have some form of trees that scatter the landscape.
