• Western Ghats and Eastern Ghats

The Himalayan Mountains

• The Himalayan Mountains are in the north of the Indian subcontinent.
• The Himalayan Mountains are divided into three parallel ranges, viz. the Great Himalaya or Himadri, the Middle Himalaya or Himachal and the Shivalik.
  (i) The Great Himalaya: This is the northernmost range. The highest peaks of the world are located in this range.
  (ii) The Middle Himalaya: This range is towards south of the Great Himalayas. Many popular hill stations are in this range.
  (iii) The Shivalik: This is the southernmost range. The elevation in this range is low compared to in the other two ranges.

The Northern Plains

• The Northern Plains lie to the south of the Himalayas.
• These plains are formed by the rivers; the Indus, the Ganges and the Brahmaputra and their tributaries.
• The lands are highly fertile in this region. Hence, this region has very high population density.

The Great Indian Desert

• The Great Indian Desert lies in the western part of India.
• This is a dry, hot and sandy stretch of land.
• There is very little vegetation in this region. This is also called the Thar Desert.

The Deccan Plateau

• The Deccan Plateau lies towards south of the Northern Plains.
• This is triangular in shape.
• There are many hill ranges and valleys in this region, e.g. Aravali hills, the Vindhyas and the Satpuras.
• The Deccan Plateau is rich in minerals.
• Narmada and Tapi are important rivers which flow through the Deccan Plateau. These rivers flow towards west and drain into the Arabian Sea.
• Western Ghats and Eastern Ghats
  • The Western Ghats mark the western boundary of the Deccan Plateau, while the Eastern Ghats mark the eastern boundary.
  • The Western Ghats are almost continuous but the Eastern Ghats are broken and uneven.

The Coastal Plains

• The Coastal Plains lie to the west of the Western Ghats and to the east of the Eastern Ghats.
• The western coastal plains are very narrow.
• The eastern coastal plains are much broader.
• The rivers Mahanadi, Godavari, Krishna and Kaveri flow in this region. These are east-flowing rivers and drain into the Bay of Bengal. These rivers have formed deltas at their mouth.
• These deltas are highly fertile.
• Delta is a landform which is formed at the mouth of a river.
• The place where a river meets an ocean is called the mouth of the river.
