What is the primary objective of geochemical mapping?

  1. To identify areas with high mineral potential

  2. To assess the environmental impact of mining activities

  3. To determine the chemical composition of rocks and soils

  4. To locate groundwater resources


Correct Option: C
Explanation:

Geochemical mapping involves the systematic collection and analysis of rock, soil, and water samples to determine their chemical composition. This information is used to identify areas with high mineral potential, assess the environmental impact of mining activities, and locate groundwater resources.
