The term "continent" refers to a big region of land that is partially surrounded by oceans. North America, South America, Asia, Australia, Europe, Antarctica, and Africa are the seven continents. The only continents wholly in the Southern Hemisphere are Australia and Antarctica. Asia, Australia, and South America are the three continents where savanna and temperate grasslands can be found. Grasslands can be found on every continent except Antarctica. Because most grasslands are in the temperate zone, they experience seasonal fluctuations. Glaciers have buried 98 percent of the land. Because it is the farthest away from the equator, this continent receives very little sunshine. It reflects the limited quantity of solar energy it receives back into space.
