What is the process of breaking down rocks and minerals into smaller particles called?

  1. Weathering

  2. Erosion

  3. Deposition

  4. Compaction


Correct Option: A
Explanation:

Weathering is the process of breaking down rocks and minerals into smaller particles due to exposure to natural elements like wind, water, and temperature changes.

Which layer of soil is the most fertile and contains the most organic matter?

  1. Topsoil

  2. Subsoil

  3. Parent material

  4. Bedrock


Correct Option: A
Explanation:

Topsoil is the uppermost layer of soil, rich in organic matter, nutrients, and microorganisms, making it the most fertile layer for plant growth.

What is the process of removing valuable minerals or other geological materials from the Earth called?

  1. Mining

  2. Quarrying

  3. Extraction

  4. Excavation


Correct Option: A
Explanation:

Mining is the process of extracting valuable minerals or other geological materials from the Earth, typically involving digging, drilling, or blasting.

Which type of mining involves extracting minerals from underground?

  1. Surface mining

  2. Underground mining

  3. Open-pit mining

  4. Strip mining


Correct Option: B
Explanation:

Underground mining involves extracting minerals from beneath the Earth's surface, typically through tunnels, shafts, or boreholes.

What is the term for the removal of soil and rock to expose underlying mineral deposits?

  1. Overburden removal

  2. Excavation

  3. Quarrying

  4. Strip mining


Correct Option: A
Explanation:

Overburden removal is the process of removing soil and rock that lie above a mineral deposit to expose it for extraction.

Which type of mining involves removing large amounts of soil and rock to expose mineral deposits near the surface?

  1. Surface mining

  2. Underground mining

  3. Open-pit mining

  4. Strip mining


Correct Option: C
Explanation:

Open-pit mining involves digging a large open pit to extract minerals near the Earth's surface.

What is the term for the process of separating valuable minerals from the surrounding rock or soil?

  1. Beneficiation

  2. Extraction

  3. Smelting

  4. Refining


Correct Option: A
Explanation:

Beneficiation is the process of separating valuable minerals from the surrounding rock or soil to increase their concentration.

Which type of mining involves extracting minerals from the Earth's surface by removing thin layers of soil and rock?

  1. Surface mining

  2. Underground mining

  3. Open-pit mining

  4. Strip mining


Correct Option: D
Explanation:

Strip mining involves removing thin layers of soil and rock from the Earth's surface to extract minerals.

What is the term for the process of extracting metals from their ores?

  1. Smelting

  2. Refining

  3. Electrolysis

  4. Hydrometallurgy


Correct Option: A
Explanation:

Smelting is the process of extracting metals from their ores by heating them to high temperatures, causing the metal to separate from the other elements.

Which type of mining involves extracting minerals from the Earth's surface using water jets?

  1. Hydraulic mining

  2. Placer mining

  3. Dredging

  4. Panning


Correct Option: A
Explanation:

Hydraulic mining involves using high-pressure water jets to break down and move soil and rock to extract minerals.

What is the term for the process of purifying metals by removing impurities?

  1. Smelting

  2. Refining

  3. Electrolysis

  4. Hydrometallurgy


Correct Option: B
Explanation:

Refining is the process of purifying metals by removing impurities to improve their quality and properties.

Which type of mining involves extracting minerals from the Earth's surface using a suction device?

  1. Hydraulic mining

  2. Placer mining

  3. Dredging

  4. Panning


Correct Option: C
Explanation:

Dredging involves using a suction device to extract minerals from the Earth's surface, typically from underwater or riverbeds.

What is the term for the process of extracting metals from their ores using an electric current?

  1. Smelting

  2. Refining

  3. Electrolysis

  4. Hydrometallurgy


Correct Option: C
Explanation:

Electrolysis is the process of extracting metals from their ores using an electric current, causing the metal to separate from the other elements.

Which type of mining involves extracting minerals from the Earth's surface using a simple pan?

  1. Hydraulic mining

  2. Placer mining

  3. Dredging

  4. Panning


Correct Option: D
Explanation:

Panning is a simple method of extracting minerals from the Earth's surface by swirling a pan filled with soil and water to separate the heavier minerals from the lighter materials.

What is the term for the process of extracting metals from their ores using chemical reactions?

  1. Smelting

  2. Refining

  3. Electrolysis

  4. Hydrometallurgy


Correct Option: D
Explanation:

Hydrometallurgy is the process of extracting metals from their ores using chemical reactions in aqueous solutions.
