CBSE NCERT Solved Question Answer
Q1. Which area in India receives the highest rainfall in the world?
Mawsynram in Meghalaya receives the highest rainfall in the world.
Q2. What is Natural Vegetation?
The grasses, shrubs and trees, which grow on their own without interference or help from human beings are called natural vegetation.
Q3. How is the climate of India described and why?
The climate of India has broadly been described as Monsoon type. Monsoon is taken from the Arabic word ‘mausim’, which means seasons. Due to India’s location in the tropical region, most of the rain is brought by monsoon winds.
Q4. What is the difference between weather and climate?
Weather is about day to day changes in the atmosphere. It includes changes in temperature, rainfall and sunshine etc.
Climate is about the average weather condition, which have been measured over many years.
Q5. Name the factors that affect the climate of a place.

Q6. What steps are being taken by the government to protect wildlife in India?
In order to protect the animals
(i) Many national parks, sanctuaries and biosphere reserves have been set up.
(ii) The Government has also started Project Tiger and Project Elephant to protect these animals.
We can also contribute in conserving wildlife. You can refuse to buy things made from parts of the bodies of animals such as their bones, horns, fur, skins, and feathers. Every year we observe wildlife week in the first week of October, to create awareness of conserving the habitats of the animal kingdom.
Q7. How are forests useful to us?
- Plants release oxygen that we breathe and absorb carbon dioxide.
- The roots of the plants bind the soil; thus, they control soil erosion.
- Forests provide us with timber for furniture, fuel wood, fodder, medicinal plants and herbs, lac, honey, gum, etc.
- Forests are the natural habitat of wild life.
Q8. Write few lines on the wildlife of India.
· The tiger is our national animal. It is found in various parts of the country.
Gir forest in Gujarat is the home of Asiatic lions.
· Elephants and one-horned rhinoceroses roam in the forests of Assam. Elephants are also found in Kerala and Karnataka.
· Camels and wild asses are found in the the Great Indian desert and the Rann of Kuchchh.

Q9. Describe the major seasons in India.
COLD WEATHER SEASON OR WINTER
During the winter season, cool, dry winds blow from north to the south. The sun rays do not fall directly in the region as a result, the temperatures are quite low in northern India.
HOT WEATHER SEASON OR SUMMER
In the hot weather season sun rays more or less directly fall in this region. Temperature becomes very high. Hot and dry winds called loo, blow during the day.
SOUTH WEST MONSOON SEASON OR RAINY SEASON
This season is marked by the onset and advance of monsoon. The winds blow from Arabian Sea and Bay of Bengal towards the land. They carry moisture with them. When these winds strike the mountain barriers, rainfall occurs.
SEASON OF RETREATING MONSOONS OR AUTUMN
Winds move back from the mainland to the Bay of Bengal. This is the season of the retreating monsoons. The southern parts of India, particularly Tamil Nadu and Andhra Pradesh receive rainfall in this season.
Q10. Explain the different types of vegetation found in India.
TROPICAL RAIN FOREST
Tropical Rain Forests occur in the areas which receive heavy rainfall. They are so dense that sunlight doesn’t reach the ground. Many species of trees are found in these forests, which shed their leaves at different times of the year. As a result, they always appear green and are called evergreen forest. Important trees found in these forests are mahogany, ebony and rosewood. Andaman an Nicobar Islands, parts of North-
Eastern states and a narrow strip of the Western slope of the Western Ghats are home of these forests.
TROPICAL DECIDUOUS FORESTS
In a large part of our country we have this type of forest. These forests are also called monsoon forests. They are less dense. They shed their leaves at a particular time of the year. Important trees of these forests are sal, teak, peepal, neem and shisham.
They are found in Madhya Pradesh, Uttar Pradesh, Bihar, Jharkhand, Chhattisgarh, Orissa, and in parts of Maharashtra.
This type of vegetation is found in dry areas of the country. The leaves are in the form of spines to reduce the loss of water. Cactus, khair, babool, keekar are important and are found in the states of Rajasthan, Punjab, Haryana, Eastern slopes of Western Ghats and Gujarat.
A wide range of species is found in the mountains according to the variation in height. With increase in height, the temperature falls. At a height between 1500 metres and 2500 metres most of the trees are conical in shape. These trees are called coniferous trees. Chir, Pine and Deodar are important trees of these forests.
These forests can survive in saline water. They are found mainly in Sunderbans in West Bengal and in the Andaman and Nicobar Islands. Sundari is a well-known species of trees in mangrove forests after which Sunderbans have been named
