(Source: 6th NCERT Geography Chapter 8)

1.Broadly, the major seasons recognised in India are:
• Cold Weather Season (Winter) December to February
• Hot Weather Season (Summer) March to May
• Southwest Monsoon Season (Rainy) June to September
• Season of Retreating Monsoon (Autumn) October and November
 
2.Hot and dry winds called loo, blow during the summer days.
3.The climate is about the average weather condition,which have been measured over many years.
4.The climate of India has broadly been described as Monsoon type.
5.Monsoon is taken from the Arabic word ‘mausim’, which means seasons.
6.Due to India’s location in the tropical region, most of the rain is brought by monsoon winds.
7.The climate of a place is affected by its location, altitude, distance from the sea, and relief.
 
8.Vegetation of India can be divided into five types –
a.Tropical evergreen forest,
b.Tropical deciduous forest,
c.Thorny bushes,
d.Mountain vegetation and
e.Mangrove forests.

9.Tropical Evergreen Forest:
Tropical Rain Forests occur in the areas which receive heavy rainfall. Important trees found in these forests are mahogany, ebony and rosewood. Andaman and Nicobar Islands, parts of North-Eastern states and a narrow strip of the Western slope of the Western Ghats are home of these forests.

10. Tropical deciduous 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, Odisha, and in parts of Maharashtra.

11.Thorny Bushes:
                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.

12.Mountain Vegetation:
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.

13.Mangrove 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.

14.The tiger is our national animal.
15.Gir forest in Gujarat is the home of Asiatic lions.
16.Elephants and one-horned rhinoceroses roam in the forests of Assam.
17.Elephants are also found in Kerala and Karnataka.
18.Camels and wild asses are found in the Great Indian desert and the Rann of Kuchchh respectively.
19.Wild goats, snow leopards, bears, etc. are found in the Himalayan region.
20.The peacock is our national bird.
21.The Government has also started Project Tiger and Project Elephant to protect these animals.
22.Every year we observe wildlife week in the first week of October, to create awareness of conserving the habitats of the animal kingdom.
23.Some birds such as the Pelican, Siberian Crane, Stork, Flamingo, Pintail Duck and Curlew migrate to our country in the winter season every year.
24.Siberian Cranes migrate from Siberia. They arrive in December and stay till early March.
