D Correct answer
Explanation

Drainage is the process by which water is removed from the soil.

Multiple choice

What is desertification?

  1. The process of land degradation in arid, semi-arid, and dry sub-humid areas

  2. The process of land degradation in humid areas

  3. The process of land degradation in polar regions

  4. The process of land degradation in mountainous regions
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Desertification is the process of land degradation in arid, semi-arid, and dry sub-humid areas. It is caused by a combination of factors, including climate change, overgrazing, deforestation, and poor agricultural practices.

Multiple choice

Which type of weathering involves the breakdown of rocks by the action of water?

  1. Mechanical weathering

  2. Chemical weathering

  3. Biological weathering

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

Chemical weathering is the process by which rocks are broken down by the action of water, acids, and other chemicals.

Multiple choice

What is the process of breaking down rocks into smaller pieces by the action of wind called?

  1. Abrasion

  2. Attrition

  3. Deflation

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

Abrasion is the process of breaking down rocks into smaller pieces by the action of wind-blown sand and other particles.

Multiple choice

What is the process of breaking down rocks into smaller pieces by the action of temperature changes called?

  1. Mechanical weathering

  2. Chemical weathering

  3. Biological weathering

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

Exfoliation weathering is the process of breaking down rocks into smaller pieces by the action of temperature changes, causing the outer layers of the rock to flake off.

Multiple choice

Which type of weathering involves the breakdown of rocks by the action of pressure?

  1. Mechanical weathering

  2. Chemical weathering

  3. Biological weathering

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

Mechanical weathering is the process by which rocks are broken down into smaller pieces by the action of pressure, such as the weight of overlying rocks or the movement of tectonic plates.

Multiple choice

What is the process of breaking down rocks into smaller pieces by the action of ice called?

  1. Abrasion

  2. Attrition

  3. Deflation

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

Frost wedging is the process of breaking down rocks into smaller pieces by the action of ice, which expands and contracts in cracks and crevices, causing the rock to break apart.

Multiple choice

What is the process of breaking down rocks into smaller pieces by the action of salt called?

  1. Abrasion

  2. Attrition

  3. Deflation

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

Salt weathering is the process of breaking down rocks into smaller pieces by the action of salt, which crystallizes in cracks and crevices, causing the rock to break apart.

Multiple choice

What is the process of breaking down rocks into smaller pieces by the action of animals called?

  1. Abrasion

  2. Attrition

  3. Deflation

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

Bioturbation is the process of breaking down rocks into smaller pieces by the action of animals, such as burrowing and digging, which exposes the rock to weathering agents.

Multiple choice

What is the process of breaking down rocks into smaller pieces by the action of wind called?

  1. Abrasion

  2. Attrition

  3. Deflation

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

Deflation is the process of breaking down rocks into smaller pieces by the action of wind, which removes fine particles from the surface of the rock.

Multiple choice

What is the process of breaking down rocks into smaller pieces by the action of waves called?

  1. Abrasion

  2. Attrition

  3. Deflation

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

Abrasion is the process of breaking down rocks into smaller pieces by the action of waves, which carry sand and other particles that wear away the rock.

Multiple choice

Which type of weathering involves the breakdown of rocks by the action of glaciers?

  1. Mechanical weathering

  2. Chemical weathering

  3. Biological weathering

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

Mechanical weathering is the process by which rocks are broken down into smaller pieces by the action of glaciers, which scrape and grind the rock as they move.

Multiple choice

How do seawalls and other hard structures work to prevent coastal erosion?

  1. By reflecting wave energy away from the shoreline

  2. By absorbing wave energy and dissipating it

  3. By trapping sediment and building up the beach

  4. By stabilizing the shoreline with vegetation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Seawalls and other hard structures work by reflecting wave energy away from the shoreline, preventing it from eroding the coast.
