Question

How does relief and rainfall influence the distribution of natural vegetation in India? Explain.

Answer 1

Hint:
> India has a vast topography and relief features varying from north to south and west to east.
> These features are formed during the northward movement of Indian plate towards the Eurasian plate.
> different reliefs have varied conditions of temperature and moisture quantity which is essential for distributing natural vegetation.

Complete answer:
Vegetation refers to the plant species in an ecological frame. The forest implies the natural vegetation which forms a complex ecosystem. The physical, geographical, climatic, and ecological factors determine the type of forest and vegetation.
In the Western Ghats, the western slopes receive rainfall of more than 200 cm. The tropical evergreen forests are found on a large scale due to heavy rainfall.
lofty trees are found here with a thick canopy.
In northern plains- The vegetation consists of palm and acacias in the areas with rainfall of 100cm to 200 cm. These are moist deciduous forests. Trees drop their leaves in winter.
Desert areas- with rainfall of around 50-100cm .vegetation is dry thorny bushes and savanna type grasslands.
Mountainous region-Precipitation is mostly in the form of snow. The coniferous trees and wet temperate forests are found at the height of 1000 to 2000cm.
Coastal region- these are mainly littoral and swamp forests.
Mangroves are especially found in these regions, occurring around deltas, or creeks.

Note:
> The relief affects vegetation as the type of land determines the vegetation, woodlands, fertile land used, and dry and rough terrain have grasslands.
> Thorny bushes and plants such as cactus, mangrove forests, swamps are in sandy soils.
> The thorny bush trees have long roots which, in search of water, penetrate deep into the soil.
> To reduce evaporation, the leaves are dense and thin. Some examples of trees include acacias, palms, and cacti.
