Flatlands are vast expanses of land with minimal variations in elevation. They are perfect for agriculture, particularly for crops that require large tracts of land to grow. Synonyms for flatlands include plains, prairies, steppes, savannas, pampas, and plateaus. Plains are generally treeless and have a relatively flat terrain. Prairies feature long grasses and are common in North America. Steppes are grassy plains that are usually found in Eurasia. Savannas are open grasslands with scattered trees and are common in Africa. Pampas are flat grassy plains that are common in South America. Plateaus are raised flatlands with steep sides and are commonly found in Australia and Africa.
