Answer: A

Explanation:

The Southern Plateau is a triangular landmass located south of the Narmada River. The Satpura range forms its broad base in the north, while the Mahadev, Kaimur Hills and the Maikal Range form its eastern extensions. The Southern Plateau is high in the west and has a low slope towards the east. A part of this plateau is also seen in the north-east. It is locally known as 'Meghalaya', 'Karbi Anglong Plateau' and 'North Cachar Hills'. It is separated from the Chhota Nagpur Plateau by a fault. The three important ranges from west to east are Garo, Khasi and Jaintia. Hence, statement 1 is correct, while statement 2 is incorrect.

Answer: C

Explanation:

Land, water, air, plants and animals together form the natural environment. The solid crust or hard upper layer of the earth is called lithosphere. It is made up of rocks and minerals and is covered with a thin layer of soil. Hence statement 1 is correct.

The lithosphere is the region which provides us with forests, land for agriculture and human settlements, grasslands for grazing animals. It is a source of mineral wealth as well. Hence, statement 2 is correct.

Answer: C

Explanation:

Mountain rainfall occurs in the Western Ghats. This rainfall occurs due to the moist air hitting the western slope of the Ghats and rising up. Hence, option (c) is correct.

Answer: A

Explanation:

The height of the Western Ghats increases from north to south. The peaks of this part are high. Such as Anai Mudi (2,695 m) and Doda Betta (2,633 m). The highest peak of the Eastern Ghats is Mahendragiri (1,500 m). The hills of Shevrai and Javed are located in the south-west of the Eastern Ghats. Hence, option (a) is correct.

Answer: C

Explanation:

The Thar Desert is located on the western edge of the Aravalli Hills. It is an undulating plain covered with sand dunes. This region receives less than 150 mm of rainfall per year. Vegetation is very less in this dry climate area. A few streams are seen only during the rainy season and after that they merge into the sand. Due to insufficient water, they are unable to reach the sea. Only 'Luni' is the largest river of this region. Barkan (crescent shaped sand dune) is spread over a very large area. Hence, statements 1 and 2 both are correct.
