Multiple choice

What is the term used to describe the process of ice breaking up and forming icebergs?

  1. Calving

  2. Ablation

  3. Sublimation

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

Calving is the term used to describe the process of ice breaking up and forming icebergs, typically occurring at the edges of glaciers or ice shelves.

Multiple choice

What is the term used to describe the gradual filling in of a lake or pond over time?

  1. Eutrophication

  2. Oligotrophication

  3. Siltation

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

Siltation refers to the accumulation of sediment and organic matter in a lake or pond, leading to its gradual filling in.

Multiple choice

Which of the following is a common type of pond formed by the collapse of a sinkhole?

  1. Vernal Pond

  2. Oxbow Pond

  3. Ephemeral Pond

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

Sinkhole ponds are formed when the roof of an underground cavern collapses, creating a depression that fills with water.

Multiple choice

What is the process by which sediment and organic matter accumulate at the bottom of a lake or pond?

  1. Eutrophication

  2. Oligotrophication

  3. Siltation

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

Siltation refers to the accumulation of sediment and organic matter at the bottom of a lake or pond, leading to its gradual filling in.

Multiple choice

  1. By absorbing wave energy.

  2. By trapping sediment.

  3. By stabilizing shorelines.

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

Coastal wetlands help to mitigate erosion by absorbing wave energy, trapping sediment, and stabilizing shorelines.

Multiple choice

What is the role of tidal flats in mitigating erosion?

  1. They help to trap sediment.

  2. They help to stabilize shorelines.

  3. They help to absorb wave energy.

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

Tidal flats help to mitigate erosion by trapping sediment.

Multiple choice

Which of the following is NOT a mode of sediment transport?

  1. Bed load

  2. Suspended load

  3. Wash load

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

Saltation is a process where sediment particles are lifted from the bed and transported in a series of short jumps or bounces, while bed load, suspended load, and wash load are all modes of sediment transport.

Multiple choice

Which of the following sediment characteristics has the greatest influence on its transportability?

  1. Size

  2. Shape

  3. Density

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

Sediment size has the greatest influence on its transportability, as smaller particles are more easily entrained and transported by flowing water.
