What describes broadly open, continuous, and mostly flat areas dominated by grasses?

The term that describes broadly open, continuous, and mostly flat areas dominated by grasses is grasslands. Grasslands are characterized by their vast expanses, where grasses are the primary vegetation. These regions can support a diverse array of wildlife and are typically found in areas where rainfall is limited, making it difficult for trees and larger plants to thrive.

Grasslands play a crucial role in various ecosystems by supporting herbivores and the predators that rely on them. They can exist in different forms, such as prairies, savannas, and steppes, distinguished by their specific climate, geographical location, and types of grasses.

In contrast, woodlands are characterized by the presence of a significant number of trees but can also include grassy areas, forests are densely populated with trees and have a more closed canopy, and deserts are arid regions with sparse vegetation, primarily consisting of drought-resistant plants rather than grasses. Hence, grasslands perfectly fit the description of broad, continuous plains dominated by grasses.
