A temperate grassland area may hold steppes and hills with mountains near the edges. Savanna grasslands may be found beside deserts and sometimes contain plateaus.
Grassland biomes are rolling fields of grass that cover large amounts of terrain. Climate, soil and latitude determine what types of grasses and plants grow there, and a single grassland biome can support more than one type of grass. Grasslands are transitional locations found between forest and desert biomes. Grasslands are very hot in the summer and very cold in the winter, with thin soil that can’t support large flora. Examples of grassland biomes are the North American prairie, the steppes of Eurasia and the Pampas of South America. About one-fourth of the Earth’s land area is covered in grassland biomes.
