GEOLOGICAL BACKGROUND
These processes over millions of years have created and modified the physical features as they appeared to us today.
The Indian Peninsula was part of Gondwana Land 200 million years ago Gondwana Lands were spilled into pieces and this peninsular Indian plate moved towards the northeast and collided with the much larger Eurasian plate the present form of the Himalayas is a result of this process.
The breaking off of the Northern Corners of the peninsular plateau with the formation of a large basin. This created the very extensive, flat northern plains of India the Indian landmass displays great relief variations the Peninsula plateau is one of the most ancient land blocks on the Earth's surface.
PHYSICAL FEATURES OF INDIA
1. The Himalayas
2. The Indo- Gangetic plain
3. The peninsular plateau
4. The coastal plains
5. The deserts
6. The islands
The Himalayas: the Himalayan ranges run in the West east direction in the form of an arc with a distance of about 2400 kilometers remove strange is known as the greater Himalayas or Himadri. They differ from 500 kilometers in the western regions to 200 kilometers in central and eastern regions the lesser Himalayas ranges consist of the famous value of Kashmir the Kangra and Kullu in Himachal Pradesh. The Himalayas are covered with snow. The southernmost range of the Himalayas as the servlets extend over a width top 10 to 50 kilometers. The formation of the Himalayas influence the climate in various way the Himalayas are the reason for summer rains and monsoon-type climate in regions that are beyond the western ghats of India. In its absence, this region would have remained dry. Glaciers form so many rivers for example that are Ganga, Brahmaputra, Indus, etc. Apple is the most crop irrigated in the Himalayas.
The easternmost boundary of the Himalayas is the Brahmaputra Valley. Regionally the Pravinjala are known as Pataki Hills.
The southern range of the Himalayas is the Shivaliks extends over a width of 10 to 50 kilometers Jammu Hills in the Jammu region are in Arunachal Pradesh the valleys lying between the luxury Himalayas and Shivaliks Ranges are called dun Dehradun.
The Indo-Gangetic Plain: The interaction of the three Himalayan rivers Indus Ganga and Brahmaputra and their tributaries resulted in the formation of the creator not playing in the beginning.
The indo gangetic planes were divided into 3 divisions:
1. The western part
2. The central part
3. The eastern part
The Western part: The western part was formed by the Indus and its tributaries the Jhelum, the Ravi, the Beas and Sutlej flowing from the Himalayas. Most of the Indus River basin is located in Pakistan leaving a minor portion of the Punjab and Haryana plains in India. In the region, the doab features dominate the fertile land between the rivers.
The central part: The central part is known as the Gangetic Plain. It extends from the river Ghgggar to Teesta. This part is mainly spread in the states of Uttar Pradesh, and Bihar, and partly in Haryana, Jharkhand, and West Bengal.
The Eastern part: The eastern part of the plain exists mostly in the Brahmaputra valley of Assam and the river of Brahmaputra is mainly responsible for its formation.
The Himalayan rivers while flowing down deposit gravel and pebbles elements in a narrow belt of eight to 16 kilometers, found parallel to uphill shops however two migrants at the time of India partition most of the terrier zone has now been cleared and used for agricultural operations small rivers and streams flow underground through Bhabar and appear in lower areas and formative a mercy region called Terai. Bhabar is porous in nature.
The Peninsular Plateau: The peninsular plateau is three sides of water and one side of land. It is mainly composed of the old crystalline and metamorphic rock. A large amount of metallic and nonmetallic mineral resources are found in the Indian plateau. It has broad and shallow values with rounded hills. The topography of the plateau is slightly titled towards the East and the Western and Eastern Guards from the Western and eastern edges respectively. The southernmost tip of the plateau is Kanya Kumari.
The portion of the peninsula plateau lying to the south of Narmada, a triangular mass, is called the Deccan Plateau. Satpura Range is from the Deccan plateau's north edge while the Mahadev, the Kanimuru Range, and a portion of the Maikal range are the eastern edges. Western guards, eastern guards, and Nilgiris from the western and eastern and southern boundaries effectively.
The peninsula plateau consists of two broad divisions namely, the central highlands and the Deccan plateau. On the physical map of India excellent to the south of the Gangetic plains and north of the river Narmada, you can identify the central highlands. The prominent plateau here is Malwa Plateau on the western side and towards the east there is a Chota Nagar plateau. In comparison the Gangteic Plains region is dry the rivers are not perennial. The irrigation per the second crop depends on the deep tube wells and tanks identified reverse that flow in the northern side of central highlands Chotanagar plate is rich in mineral resources.

The Coastal Plains: The weather coast starts from the Rann of Kutch and ends at Kanyakumari. It is three parts
1. Konkan coast (This is the northern part which touches Maharashtra and Goa
2. Canara coast (It is the middle part that touches the coastal plains of Karnataka.)
3. Malabar coast (It is the southern part that touches Kerala.)
The Deserts: the desert consists of sand it is not used for constructing any buildings and India has one desert which is the desert.
The Islands: there are two groups of Islands- Andaman and Nicobar Islands stretched in Bengal and Lakshwadeep Islands in the Arabian Sea. Andaman and Nicobar Islands is an elevated portion of submerged mountain parts running from the Myanmar Mountain Arkan Yoma. Lakshadweep island is of coral origin It is total geographical area is 32sq.Kms. Andaman and Nicobar's capital is Port Blair.
