Geomorphic Processes Questions

Multiple choice

Which human activity is a major contributor to coastal erosion?

  1. Beach Nourishment

  2. Mangrove Restoration

  3. Seawall Construction

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

Seawalls, while intended to protect coastal areas from erosion, can disrupt natural sediment transport patterns and exacerbate erosion in adjacent areas.

Multiple choice

How does the construction of groynes affect coastal erosion?

  1. It reduces erosion by trapping sediment.

  2. It increases erosion by disrupting sediment transport.

  3. It has no significant impact on erosion.

  4. It enhances sediment deposition, leading to beach growth.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Groynes can disrupt the natural flow of sediment along the coast, leading to increased erosion in downdrift areas.

Multiple choice

How does the removal of sand from beaches impact coastal erosion?

  1. It reduces erosion by lowering the beach profile.

  2. It increases erosion by disrupting sediment balance.

  3. It has no significant impact on erosion.

  4. It enhances sediment deposition, leading to beach growth.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Sand removal disrupts the natural sediment balance of beaches, making them more vulnerable to erosion.

Multiple choice

  1. Lithification

  2. Diagenesis

  3. Hydrogenesis

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

Lithification is the process by which sediments are compacted and hardened into solid rock through the action of pressure, temperature, and chemical reactions.

Multiple choice

Which type of sedimentary structure is formed by the movement of water currents over the sediment surface?

  1. Ripple marks

  2. Mud cracks

  3. Cross-bedding

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

Ripple marks are sedimentary structures formed by the movement of water currents over the sediment surface, creating small, wave-like features.
