Primary Activities
Economic occupations that are directly dependent on nature, utilizing earth's resources like land, water, vegetation, and minerals.
Nomadic Herding
A primitive subsistence activity where herders rely on animals for food, clothing, and shelter, moving from place to place with their livestock in search of pasture and water.
Commercial Livestock Rearing
A specialized, capital-intensive pastoral activity practiced on vast permanent ranches to rear animals primarily for meat, wool, and hides for the global market.
Subsistence Agriculture
Farming primarily meant for local consumption, divided into primitive subsistence (shifting cultivation) and intensive subsistence agriculture.
Mining
The extraction of valuable minerals and other geological materials from the earth, influenced by physical factors (mineral deposits) and economic factors (demand and technology).

Frequently Asked Questions
What is the difference between nomadic herding and commercial livestock rearing?
Nomadic herding is primitive, involves moving with animals for survival, and is meant for local consumption. Commercial livestock rearing is modern, practiced on fixed ranches, capital-intensive, and oriented towards producing meat and wool for the global market.
Why is shifting agriculture also known as slash-and-burn agriculture?
In this method, farmers clear a patch of land by cutting and burning the trees and bushes, and the ash adds fertility to the soil until it gets exhausted, forcing them to shift to a new patch.
What factors affect the location of mining industries?
Mining location depends on physical factors (size, grade, and depth of mineral deposits) and economic factors (market demand, availability of capital, technology, and transport facilities).
