Final answer:
Savannas are tropical grasslands with scattered trees, main regions include Africa, South America, and northern Australia. Temperate grasslands experience a greater range of temperatures and less rainfall, whereas Chaparral grasslands are characterized by an environment influenced by the ocean and are dominated by shrubs.
Step-by-step explanation:
The three major types of grasslands namely, savannas, temperate grasslands, and chaparral, all differ in their climate and vegetation. The savanna is a type of grassland biome located in Africa, South America, and northern Australia. They are characterized as hot, tropical areas with temperatures averaging from 24 °C to 29 °C (75 °F to 84 °F) with an annual rainfall of 10–40 cm (3.9–15.7 in). These grasslands experience an extensive dry season, resulting in fewer forest trees, and are dominated by grasses and forbs (herbaceous flowering plants).
Temperate grasslands, on the other hand, are positioned away from the equator and experience a greater range of temperatures. They receive less rainfall compared to savannas and thus, have lower tree and shrub coverage.
The chaparral is a type of grassland found near coasts where the ocean influence causes mild wet winters and hot dry summers. This biome is dominated by shrubs and experiences frequent wildfires.
