  1. Soil analysis

  2. Geochemical soil sampling

  3. Pedochemical analysis

  4. Edaphic analysis
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Geochemical soil sampling involves the collection and analysis of soil samples to identify anomalous concentrations of elements or compounds that may have been transported from nearby mineral deposits or may be indicative of the presence of mineral deposits.

Multiple choice

Which geochemical technique involves the analysis of isotopes to identify areas with potential mineral deposits?

  1. Isotope analysis

  2. Isotopic geochemistry

  3. Radiogenic isotope analysis

  4. Stable isotope analysis
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Isotope analysis involves the determination of the isotopic composition of elements in rocks, minerals, and fluids to identify anomalies in the ratios of different isotopes, which can provide information about the age, origin, and processes involved in the formation of mineral deposits.

Multiple choice

Which of the following natural resources is most susceptible to overexploitation?

  1. Minerals

  2. Water

  3. Soil

  4. Sunlight
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Water is a renewable resource, but it can be overexploited if it is extracted at a rate faster than its natural replenishment.
