The document describes two main types of grasslands: tropical grasslands called savannas found in tropical regions with distinct rainy and dry seasons, featuring scattered trees and tall grasses; and temperate grasslands called steppes found in higher latitudes with seasonal rainfall and cold winters, where grasses lie dormant during dry periods and regrow after rain. Key adaptations of grasses in these grasslands include deep roots, small leaves, thick leaves, and the ability to go dormant, in order to conserve water through the dry seasons.
