Multiple choice

Which of the following is NOT a type of weathering process?

  1. Physical weathering

  2. Chemical weathering

  3. Biological weathering

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

Metamorphism is a geological process that involves the transformation of rocks under the influence of high temperature and pressure, while physical, chemical, and biological weathering are all processes that break down rocks and minerals at or near the Earth's surface.

Multiple choice

The process by which rocks and minerals are broken down into smaller particles by the action of living organisms is known as:

  1. Physical weathering

  2. Chemical weathering

  3. Biological weathering

  4. Metamorphism
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Biological weathering is the process by which rocks and minerals are broken down into smaller particles by the action of living organisms, such as plants, animals, and microorganisms.

Multiple choice

What is the geological formation typically used for carbon storage?

  1. Depleted oil and gas reservoirs

  2. Deep saline aquifers

  3. Unmineable coal seams

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

Carbon storage can be achieved in various geological formations, including depleted oil and gas reservoirs, deep saline aquifers, and unmineable coal seams. These formations provide suitable conditions for CO2 injection and long-term storage.

Multiple choice

Which geological formation is commonly used for storing CO2?

  1. Depleted oil and gas reservoirs

  2. Deep saline aquifers

  3. Unmineable coal seams

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

Depleted oil and gas reservoirs offer a suitable storage option for CO2 due to their existing infrastructure, well-characterized geology, and the potential for enhanced oil recovery.

Multiple choice
