These short grasses can have roots that extend 1 m (about 3 ft) deep. The height of grass correlates with the amount of rainfall it receives. Grasslands receive about 500 to 900 mm of rain per year compared to deserts, which receive less than 300 mm and tropical forests, which receive more than 2,000 mm. While temperatures are often extreme in some grasslands, the average temperatures are about -20Â°C to 30Â°C.
