Answer 1

Answer:

1. The types of mountains :

• Fold mountains: Fold mountains have their origins in the folds of the Earth. Some of the fold mountains are the Himalayas and Aravallis in the Indian subcontinent, the Alps in Europe and the Urals in Eurasia.

• Block mountains: These are formed when large areas are broken and uplifted to form horsts. The sunken areas are called grabens. The Rhine Valley and Vosges mountains are examples of graben and horst.

• Volcanic mountain: These have their origin due to volcanic activity. Mt Kilimanjaro in Africa and Mt Fujiyama in Japan are examples of volcanic mountains.

2. The mountains are scantily populated because of the harsh climate. The slopes are steep and the soil is lack. These conditions are not favourable for agriculture, so the mountains are scantily populated.

3. Australia is the smallest continent in the world. It is often called the “island continent”.

4. A complex relationship between all the living and nonliving things (plants, animals, organisms, sun, water, climate, etc.) interact with each other is known as an ‘Ecosystem’. Ecosystems are the foundation of ‘Biosphere’ and maintain the natural balance of the earth.
