Peninsula
Mountain ranges in the Eastern part of India forming its boundary with Myanmar are collectively called
Purvachal
The western coastal strip of Goa is called

What are tectonic plates
The convectional currents below the Earths crust split the crust into a number of pieces. These pieces are called Tectonic plates e.g Eurasian plate , Indo - Australian plate
Which continents of today were a part of the Gondwanaland
South America, South Africa, Antarctica, Asia
Three major divisions of the Himalayas from north to south
Himadri / Great or inner Himalayas - This the continuous range consisting of the highest peaks.
Himachal/ Lesser Himalayas- The range lying to the south of the Himadri is known as Himachal or lesser Himalayas .
Shiwaliks - The outermost range of the Himalayas is known as the shiwaliks. These are the foothill ranges and represent the southernmost division of the Himalayas.
Which plateau lies between the Aravali and the Vindhya ranges
Malwa plateau
Features of the islands
The islands are composed of coral deposits on the sea bed
It has a great diversity of Flora and Fauna
The pitti island in the group has a bird sanctuary
Distinguish between converging and diverging tectonic plates
Converging tectonic plates- these plates come towards each other
Diverging tectonic plates- these plates move away from each other
Distinguish between bhangar and Khadar
Bhangar - It is old alluvial soil.
- it is found away from ten river.
- it is less fertile.
- the soil is dark in colour.
Khadar- if us new alluvial soil.
- it is found near ten river basin.
- it is very fertile.
- the soil is light in colour.
Distinguish between Eastern and Western Ghats
Eastern Ghats- mark the Eastern edge of the Deccan plateau.
- they are discontinuous and irregular and dissected by rivers draining the Bay of Bengal .
- they lie parallel to the Eastern coast along ten Bay of Bengal.
- Average height is 600 m
Western Ghats- mark ten western edge of ten Deccan plateau.
- they are continuous and can be crossed through passes only.
- they lie parallel to the western coast along ten Arabian Sea.
- Average height is 1600 m
Describe how the Himalayas were formed
The oldest landmass of India was a part of the Gondwanaland . The Gondwanaland included India , Australia , South Africa, South America and Antarctica as one single landmass . Convectional currents split the crust into a number of pieces . Therefore leading to the drifting of the Indo Australian plate towards the north after being separated from Gondwanaland.The northward drift resulted in the collision of this plate with the much larger Eurasian plate . Due to this collision, The sedimentary rocks which were accumulated in ten geosyncline known as ten Tethys, Asia and Himalayas.
Contrast between the relief of the Himalayan region and the Peninsular plateau
The Himalayan region: - Formed by folding process due to collision of ten Indo Australian plate with ten Eurasian plate.
- Himalayas are made up of sedimentary rocks .
- Himalayas are mountains forming an unstable zone.
- Himalayas are the most recent landforms.
- Himalayas are rich in water resources And forest wealth.
Peninsular plateau:- formed due to ten braking up and drifting of ten Gondwanaland.
- plateau contains igneous and metamorphic rocks.
- considered to be one of ten most stable land blocks.
- are one of the most ancient landmasses .
- the plateau is storehouse of minerals .
