Case Study Questions for Class 9 Social Science Geography Chapter 5 Natural Vegetation and Wild Life

Case Study Questions

Question 1:

Read the following passage and answer the questions that follows:

In mountainous areas, the decrease in temperature with increasing altitude leads to the corresponding change in natural vegetation. As such, there is a succession of natural vegetation belts in the same order as we see from the tropical to the tundra region. The wet temperate type of forests are found between a height of 1,000 and 2,000 metres. Evergreen broad-leaf trees, such as oaks and chestnuts predominate. Between 1,500 and 3,000 metres, temperate forests containing coniferous trees, like pine, deodar, silver fir, spruce and cedar, are found. These forests cover mostly the southern slopes of the Himalayas, places having high altitude in Southern and North-East India. At higher elevations, temperate grasslands are common. At high altitudes, generally, more than 3,600 metres above the sea level, temperate forests and grasslands give way to the Alpine vegetation. Silver fir, junipers, pines and birches are the common trees of these forests.

Q 1. What is montane vegetation?
Ans. The vegetation found on high altitudes is known as montane vegetation where the decrease in temperature with increasing altitude leads to the corresponding change in natural vegetation.

Q 2. What type of forests are found between 1,500 and 3,000 metres of height?

Ans. Between 1,500 and 3,000 metres, temperate forests containing coniferous trees are found that cover mostly the Southern slope of the Himalayas.

Q 3. What are the common animals found in montane forests?
