Multiple choice

Which of the following is a major source of mineral resources?

  1. Igneous Rocks

  2. Sedimentary Rocks

  3. Metamorphic Rocks

  4. All of the Above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All types of rocks can contain mineral resources. Igneous rocks are formed from the cooling and solidification of molten rock, sedimentary rocks are formed from the accumulation and compaction of sediments, and metamorphic rocks are formed from the alteration of existing rocks due to heat, pressure, or chemical reactions.

Multiple choice

What is the primary noise pollutant generated during peridotite quarrying?

  1. Blasting

  2. Crushing

  3. Hauling

  4. Drilling
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Blasting is the primary noise pollutant generated during peridotite quarrying. Blasting involves the use of explosives to break up rock, which can produce loud noises and vibrations.

Multiple choice

Which of these is NOT a type of river sediment?

  1. Sand

  2. Gravel

  3. Silt

  4. Clay
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Clay is not typically considered a river sediment as it is very fine-grained and easily suspended in water. Sand, gravel, and silt are more common types of river sediments.
