About a quarter of the world is covered with grasslands.
Grasslands are open areas of land that are large and covered with grass.
Temperate areas have four seasons with cold winters, hot summers, cool falls, and warm springs. In the winter the ground on the prairie is usually covered with about 20 inches of snow. It is hot all the time in tropical areas and the two seasons are rainy and dry. Grasslands are also called savannas and steppes. There are many other names for grasslands too.
