History of the Steppe Introduction Geography. The Steppe (aka the Eurasian Steppe) is a vast strip of land stretching from Ukraine to Mongolia. The term steppe denotes grassland: a low-precipitation region with enough rain for grass, but not enough for trees (see Climates and Biomes).
A desert is a barren area of land where little precipitation occurs and consequently living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation. About one third of the land surface of the world is arid or semi-arid. desert is a barren area of land where little precipitation occurs and consequently living conditions are hostile for plant and animal life.
