Grasslands. Grasslands are flat and open areas in which grasses grow. In temperate regions, they are located between forests. In tropical regions, grasslands are found between deserts and rainforests. Grasslands typically receive 50 to 90 centimetres of rain in a year. While temperatures can be extreme, they are usually between -20 degrees and +30 degrees Celsius. Temperatures in tropical grasslands are more stable year-round than those in temperate zones.
