Topography is the variety of shapes found on the landscape determined by slopes, elevation and aspects. The topography of grassland ecosystems is a varied landscape of gently rolling hills and prairies, rock outcrops, cliffs, gullies, and low lying areas. Diverse topography is what gives incredible variety to grassland ecosystems. Aspect refers to the direction in which a piece of land is facing. Areas that face towards the south, or the sun, are hotter and drier than areas that face north, or away from the sun. The slope of an area is the angle at which the land lies.
In the grassland biome there are plenty of plants, grass, and flowers that grow. There is a rainy season and a dry season. This is a type of environment with decent temperatures throughout the year. As a result it is easier for the plants and animals that live here to be able to survive.ome of the popular terrestrial biomes include the tundra biome, the forest biome, the grassland biome, and the desert biome. Tundra biomes are extremely cold and have very harsh conditions. They include areas of Russian and the Arctic. Only a few types of plants and animals are able to survive here.
