Natural Vegetation and Wildlife Class 7 Notes Geography Chapter 6 - PDF Download
The height of land and the type of vegetation are close related attributes. Any change in the climate causes changes to the natural vegetation of that area as the growth of vegetation is dependent on temperature, moisture, slope, and thickness of soil. These factors correspond to the type and thickness of natural vegetation from place to place.
Forests: These grow where there is enough temperature and rainfall to support a tree cover. Accordingly, dense and open forests are grown.
Grasslands: These grow in the region with moderate rain.
Shrubs: Thorny shrubs and scrubs grow in the dry region.
FAQs (Frequently Asked Questions)
1. On Which Factors Does the Growth of Vegetation Mostly Depend?
Ans: The growth of natural vegetation majorly depends on the following factors: temperature, moisture, slope, and thickness of soil.
2. Give Reasons to the Following:
Why do the Animals in the Polar Region have Thick Fur and Skin?
Why do the Leaves of Tropical Deciduous Trees Shed Away in the Dry Season?
Why Does the Thickness and Type of Vegetation Change From Place to Place?
Ans: A. Animals in the polar region possess thick fur and skin, to protect themselves from the extremely cold climatic conditions. Due to the cold climate, this region suffers from limited natural vegetation.
B. Tropical deciduous forests are found in major parts of India, Northern part of Australia and America. These areas experience seasonal changes, and thus the tropical deciduous trees shed their leaves in the dry season for saving water.
C. The thickness and type of vegetation changes from place to place, because of the change in climatic condition, landform, soil, temperature, and moisture. Depending on these factors, different types of plants and animals can survive in different types of vegetation.
