Mention one bauxite mining area in Odisha.
Show Hint
Panchpatmali is a plateau region known for its extensive and high-quality bauxite reserves.
Solution and Explanation
• Bauxite is the primary ore used to produce aluminum.
• It is formed by the decomposition of a wide variety of rocks rich in aluminum silicates.
• Odisha is the largest bauxite-producing state in India, accounting for nearly half of the country's total output.
Step 1: Identify the bauxite-rich districts of Odisha
Major deposits are found in the Koraput, Rayagada, and Kalahandi districts. These form a part of the East Coast Bauxite belt.
Step 2: Locate the most significant mining site
The Panchpatmali deposits in the Koraput district are the most important bauxite deposits in Odisha.
These deposits feed large aluminum refineries like NALCO.

Hunting and Food Gathering
The earliest human beings depended on their immediate environment for their sustenance. They subsisted on: (a) animals which they hunted; and (b) the edible plants which they gathered from forests in the vicinity. Primitive societies depended on wild animals. People located in very cold and extremely hot climates survived on hunting. The people in the coastal areas still catch fish though fishing has experienced modernisation due to technological development. Many species, now have become extinct or endangered due to illegal hunting (poaching). The early hunters used primitive tools made of stones, twigs or arrows so the number of animals killed was limited. Gathering and hunting are the oldest economic activity known. These are carried out at different levels with different orientations. Gathering is practised in regions with harsh climatic conditions. It often involves primitive societies, who extract both plants and animals to satisfy their needs for food, shelter and clothing. This type of activity requires a small amount of capital investment and operates at very low levels of technology. The yield per person is very low and little or no surplus is produced.- Examine the role of climate, water availability, and soil fertility on the distribution of world population.
