Give geographical reason: Physical factors are most important for regional development.

Answer: Because natural conditions decide the resources and opportunities available to a region.

• Relief, climate, soil, water and minerals decide what agriculture, industry and settlement a region can support.
• Plains with fertile soil and water (e.g. Ganga plain) develop agriculture, dense population and towns; regions with minerals (e.g. Chota Nagpur plateau) develop industries.
• Rugged mountains, deserts and dense forests make transport, farming and industry difficult and costly, so such regions lag behind.
• Thus physical factors form the base on which human factors such as capital, technology and government policy build regional development.
