How do climatic factors influence the vegetation cover of India explain Class 9?

Climate plays a very important role in influencing the vegetation cover of India. The areas with high temperature and high humidity support dense forests and high temperature and low humidity support thorny bushes. Areas experiencing heavy rainfall have tropical rain forests.

The Climate of the Region

Photoperiod also affects the vegetation of a place. It is the variation in duration of sunlight at different places due to differences in latitude, altitude, season and duration of the day. Hence, depending on the photoperiod, you get different kinds of vegetation at different places.

The character and extent of vegetation are mainly determined by temperature along with humidity in the air, precipitation and soil.

Projected effects of climate change across many ecosystems globally include more frequent disturbance by fire and reduced plant growth due to warmer (and especially drier) conditions. Such changes affect species - particularly fire-intolerant woody plants - by simultaneously reducing recruitment, growth, and survival.

Factors affecting vegetation

The important elements are rainfall, temperature, soil, altitude and geographical structure.

Climate change also alters the life cycles of plants and animals. For example, as temperatures get warmer, many plants are starting to grow and bloom earlier in the spring and survive longer into the fall. Some animals are waking from hibernation sooner or migrating at different times, too.

Solution : Land affects the natural vegetation directly and indirectly. The nature of land influences the type of vegetation. The fertile level is generally devoted to agriculture. The undulating and rough terrains are areas where grasslands and woodlands develop and give shelter to a variety of wildlife.

The natural vegetation depend upon the climate conditions existing in the place. For example evergreen forests grow in the region which experience heavy rainfall. Similarly, at higher altitudes, where the climate is extremely cold lichens and mosses grow.

The types of natural vegetation differ according to precipitation, soil, climate, and topography.

Hint:The five main factors which affect the climate of a region are Latitude, Altitude, relief, currents and winds and distance from the sea. Complete answer: Latitude: Climate of a region depends on the latitude where it lies.

How does the climate affect the vegetation of a particular area explain with a few examples?

Even in areas with high yearly rainfall, trees are scarce if there is not much rainfall during the warm growing season. Regions with not much rainfall and scarce vegetation are called deserts, or arid regions. Areas with somewhat greater rainfall are called semiarid regions.

Different types of soil provide basis for different types of vegetation. The sandy soils of the desert support cactus and thorny bushes while wet, marshy, deltaic soils support mangroves and deltaic vegetation. The hill slopes with some depth of soil have conical trees.

Climate, soil, the ability of soil to hold water, and the slope, or angle, of the land all determine what types of plants will grow in a particular region.

Soil Development

Climate change will influence soil moisture levels by direct climatic effects (precipitation, temperature effects on evaporation), climate induced changes in vegetation, plant growth rates, rates of soil water extraction by plants and the effect of enhanced CO₂ levels on plant transpiration.

One of the most significant impacts of climate change on plants and animals is that it destroys habitats. As the earth's temperature continues to rise, animals and plants that live and grow in colder climates are struggling to survive and might not find a suitable habitat.

Ans. The two factors on which the growth of vegetation mostly depends are : Temperature and Moisture.

The following are the characteristics of the tropical evergreen forests in India: The heights of the trees can reach up to 60 meters and above. The forest appears green throughout the year. This region has abundant vegetation of all kinds of shrubs, herbs, and creepers.

(iii)Growth of vegetation depends upon factors like temperature, moisture, slope and thickness of soil. Due to the variations in these factors from place to place, the type and thickness of vegetation also varies from place to place.

Due to heavy rainfall, tropical evergreen forests are found in this region on a large scale. 2. Indifferent mountainous regions different types of vegetation are found, at the height of 1500 to 3000 coniferous trees are found but at the height of 1000 to 2000 wet temperate forests are found. 3.

The correct answer is Tropical deciduous forests. Tropical deciduous forests are the most widespread forests of India. They are also called the monsoon forests and spread over the region receiving rainfall between 200 cm and 70 cm.

What is the relationship between climate and vegetation cover?

Vegetation can affect climate and weather patterns due to the release of water vapor during photosynthesis. The release of vapor into the air alters the surface energy fluxes and leads to potential cloud formation.

The Natural Vegetation of a country refers to the plants which grow on their own without any sort of aid from humans. The natural vegetation in India is of five types – Tropical Evergreen Forests, Tropical Deciduous Forests, Tropical Thorn Forests, Montane Forests, and Mangrove Forests.

The physical environment of forests is determined by edaphic (soil) factors and micro-climate (precipitation, light, temperature, and wind).

The natural vegetation of a place depends on different factors like rainfall, relief features and type of soil.
