Detailed explanation-1: -Characteristics of the Savanna Large herds of animals-There are often large herds of grazing animals on the savanna that thrive on the abundance of grass and trees. Warm-The savanna stays pretty warm all year. It cools down some during the dry season, but stays warm and humid during the rainy season.

Detailed explanation-2: -savanna, also spelled savannah, vegetation type that grows under hot, seasonally dry climatic conditions and is characterized by an open tree canopy (i.e., scattered trees) above a continuous tall grass understory (the vegetation layer between the forest canopy and the ground).

Detailed explanation-3: -The savannas are grasslands that have several months of dryness, followed by a rainy season. A majority of the soils in this area are Alfisols and Ultisols. These soils are very old and low in fertility, but since there is a dry season, more of the nutrients can stay in place.

Detailed explanation-4: -The soil of temperate grasslands and savanna grasslands are usually mollisols. In the savanna grasslands, however, the soil contains more sand and water drains away quickly. Mollisols are soils with a thick, dark upper layer that is extremely fertile from the growth and death of the of grasses.
