| Description: Grasslands form in the interior of continents between deserts and temperate forests Soils are rich, with deep topsoil Low-growing grasses and other nonwoody plants tolerate strong winds, sparse rain, and intervals of drought Growth tends to be seasonal – grazers and periodic fires keep trees and most shrubs from taking hold Temperate grasslands are warm in summer, cold in winter Annual rainfall is 25 to 100 centimeters (10–40 inches), with rains throughout the year Shortgrass and tallgrass prairies once dominated the North American plains Farming destroyed extensive grass roots that held topsoil, causing the Dust Bowl Picture Stats: Views: 76 Filesize: 211.53kB Height: 615 Width: 1754 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=47282 |
