3. Mountains and Plateaus
⢠The most noticeable
terrain feature of the
subcontinent is the
Himalayan Mountains.
4. ⢠Thatâs one reason itâs sometimes called the subcontinent,
because itâs like a continent in itself.
⢠When India hits Asia, the Indian plate subducts beneath the
Eurasian plate, but the crust is forced upwards, producing the
Himalayas, the worldâs tallest mountain chain.
⢠In fact, the Himalayas are still growing at about 5 mm per
year because the Indian plate is pushing in at about 67 mm
per year.

7. ⢠The Himalayas, of course, are where Mt. Everest is.
Itâs 29,035 feet high â
thatâs 5.5 miles.

9. ⢠Hindu Kush Mountains
⢠Along the western end of the Himalayas. Provide a
barrier between Afghanistan and Pakistan.
11. ⢠Khyber Pass is
here which is a
traditional route
of invasion for
everybody from
Alexander the
Great to the
British.
⢠At its
narrowest, itâs
just 15 yards
wide.
13. ⢠The rivers carry a great deal of alluvial soil (silt) that
gets deposited on the alluvial plains and makes for an
exceptionally fertile area.
⢠These plains support a massive population. Most of
Indiaâs 1 billion people live around here.

15. Offshore Islands
⢠Sri Lanka
⢠Quite tropical, with a mountain chain in the center
and rivers flowing from them.
⢠Sri Lanka is its own country and not part of India.

17. ⢠The Maldives
⢠A collection of 1,200 islands that make up an
archipelago (a collection of islands).
⢠The islands are actually the tops of volcanoes
surrounded by coral to make up smaller atolls.
⢠Theyâre short too. The highest point of the island
country is 7.5 feet above sea level.
⢠The total land area is only 115 square miles, but has
400 miles of coastline.
⢠Of the 1,200 islands, only about 200 are inhabited.

19. ⢠A better look at the atolls (low-lying tops of
submerged volcanoes, surrounded by coral reefs and
shallow lagoons).

23. Natural Resources
⢠Thereâs a lot thatâs dependent on water and soil.
⢠Those rivers and their soil provide for a lot of
irrigation and rich farmland.
⢠That makes for a lot of agriculture as well as river-
based products like fish in addition to sea fishing.
⢠The navigable rivers and the coastlines are good for
transportation.
24. ⢠Forests
⢠The timber industry is big.
⢠Rain forests produce teak, bamboo, and
sandalwood.
⢠Highland forests produce pine, fir, and others.
⢠Deforestation is a big problem, however.
