Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A drumlin is a large, elongated hill of glacial till deposited by a glacier.

Multiple choice

Which of the following is NOT a process of glacial erosion?

  1. Abrasion

  2. Plucking

  3. Freeze-Thaw Weathering

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

Chemical weathering is not a process of glacial erosion. It is a process by which rocks are broken down by chemical reactions.

Multiple choice

What is the term for the process by which glaciers pick up and transport rock fragments?

  1. Abrasion

  2. Plucking

  3. Freeze-Thaw Weathering

  4. Chemical Weathering
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Plucking is the process by which glaciers pick up and transport rock fragments.

Multiple choice

Which of the following is NOT a type of glacial deposit?

  1. Till

  2. Loess

  3. Outwash

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

Loess is not a type of glacial deposit. It is a windblown deposit of silt and clay.

Multiple choice

What is the term for a large, isolated rock left behind by a glacier?

  1. Till

  2. Loess

  3. Outwash

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

An erratic is a large, isolated rock left behind by a glacier.

Multiple choice

Which of the following is NOT a landform created by glacial erosion?

  1. Arête

  2. Cirque

  3. Moraine

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

A moraine is a landform created by glacial deposition, not erosion.

Multiple choice

What is the term for a steep-sided ridge of rock formed by glacial erosion?

  1. Arête

  2. Cirque

  3. Moraine

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

An arête is a steep-sided ridge of rock formed by glacial erosion.

Multiple choice

What is the term used to describe a steep, narrow passage between two cliffs or rock formations?

  1. Canyon

  2. Gorge

  3. Ravine

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

A gorge is a deep, narrow valley with steep sides, often formed by the erosion of a river or stream.

Multiple choice

What is the term for the process by which nutrients are released from rocks and minerals into the environment?

  1. Weathering

  2. Erosion

  3. Deposition

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

Weathering is the process by which nutrients are released from rocks and minerals into the environment. This process can be caused by a variety of factors, including wind, water, and temperature changes.

Multiple choice

What is the term used to describe the process by which mangroves trap and accumulate sediments?

  1. Accretion

  2. Erosion

  3. Deposition

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

Accretion is the process by which mangroves trap and accumulate sediments, leading to the formation and growth of mangrove habitats.

Multiple choice

What is the term used to describe a rock unit that is younger than the underlying rock unit but older than the overlying rock unit?

  1. Interbed

  2. Layer

  3. Stratum

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

An interbed is a rock unit that is sandwiched between two other rock units of different ages.

Multiple choice

What is the term used to describe the process of converting sedimentary rocks into metamorphic rocks?

  1. Weathering

  2. Erosion

  3. Metamorphism

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

Metamorphism is the process by which sedimentary rocks are subjected to high temperatures, pressures, or chemical alteration, resulting in the formation of new minerals and textures.

Multiple choice

What is the term for a large, steep-sided valley with a river or stream flowing through it?

  1. Canyon

  2. Valley

  3. Gorge

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

Canyons are deep, narrow valleys with steep sides, typically formed by the erosive action of rivers or streams over long periods of time.

Multiple choice

Liquefaction is a phenomenon in which:

  1. Soil loses its strength and behaves like a liquid

  2. Soil becomes denser and more compacted

  3. Soil erodes and is carried away by water

  4. Soil cracks and forms fissures

  5. Soil becomes impermeable to water
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Liquefaction occurs when saturated soil loses its strength and behaves like a liquid, typically due to the shaking caused by an earthquake.

Multiple choice

What is the primary human activity that contributes to coastal erosion?

  1. Agriculture

  2. Mining

  3. Construction

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

Construction activities, such as the building of seawalls and jetties, can alter the natural flow of sediment along the coast and lead to increased erosion.
