Question

write a short note on grassland (steppes and prairies)​

Answer 1

Answer:

grassland, area in which the vegetation is dominated by a nearly continuous cover of grasses. Grasslands occur in environments conducive to the growth of this plant cover but not to that of taller plants, particularly trees and shrubs. The factors preventing establishment of such taller, woody vegetation are varied.Grasslands are one of the most widespread of all the major vegetation types of the world. This is so, however, only because human manipulation of the land has significantly altered the natural vegetation, creating artificial grasslands of cereal crops, pastures, and other areas that require some form of repetitious, unnatural disturbance such as cultivation, heavy grazing, burning, or mowing to persist. This discussion, however, concentrates on natural and nearly natural grasslands.

Origin

The most extensive natural grasslands can be thought of as intermediates in an environmental gradient, with forests at one end and deserts at the other. Forests occupy the most favourable environments, where moisture is adequate for growth and survival of a tall, dense vegetation dominated by trees. Deserts are found where moisture is so lacking that a continuous, permanent vegetation cover cannot be maintained. Grasslands lie between these two extremes.

Answer 2

Grasslands are large open areas covered with grass that is mainly used for grazing.

• Steppes are dry, grassy plain that occurs in the temperate climate that lies between the tropic and polar regions.
• They receive around 25 to 50 centimeters of rain per year, therefore, they are semi-arid.
• The largest temperate grassland in the world is European Steppe that extends from Hungary to China, reaching one-fifth the way around the Earth.
• Prairies are huge stretches of flat grassland with moderate temperature, rainfall, and lesser trees.
• The best example is the North American Prairies.
• They are ideal for agriculture.
