Geomorphic Processes Questions

Multiple choice

Which type of pilgrimage is most likely to cause soil erosion?

  1. Walking pilgrimage

  2. Cycling pilgrimage

  3. Car pilgrimage

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

Car pilgrimages involve large numbers of people driving to a particular destination. This type of pilgrimage can lead to deforestation, as new roads are built to accommodate the traffic. It can also lead to overgrazing, as the animals are displaced from their natural habitat. Additionally, the construction of parking lots and other infrastructure can also contribute to soil erosion.

Multiple choice

What is the term used to describe the sudden release of water from a glacier or ice sheet?

  1. Glacial outburst flood

  2. Ice avalanche

  3. Serac collapse

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

A glacial outburst flood is a catastrophic event characterized by the sudden release of large volumes of water from a glacier or ice sheet, often resulting in devastating downstream impacts.

Multiple choice

What is the term used to describe the process of ice loss from the surface of a glacier or ice sheet through evaporation and sublimation?

  1. Ablation

  2. Accumulation

  3. Calving

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

Ablation refers to the loss of ice from the surface of a glacier or ice sheet through evaporation and sublimation, contributing to the overall mass balance and retreat of glaciers.

Multiple choice

What is the term used to describe the process of ice loss from the front of a glacier or ice sheet through the breaking off of large pieces of ice?

  1. Calving

  2. Ablation

  3. Accumulation

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

Calving refers to the process of ice loss from the front of a glacier or ice sheet through the breaking off of large pieces of ice, contributing to the overall mass balance and retreat of glaciers.

Multiple choice

What is the term used to describe the process of ice accumulation on the surface of a glacier or ice sheet through snowfall and deposition?

  1. Accumulation

  2. Ablation

  3. Calving

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

Accumulation refers to the process of ice accumulation on the surface of a glacier or ice sheet through snowfall and deposition, contributing to the overall mass balance and growth of glaciers.

Barchans are crescent-shaped dunes, stars are star-shaped dunes, and parabolic dunes are U-shaped dunes.

Multiple choice

What is a playa?

  1. A dry lake bed

  2. A type of sand dune

  3. A desert oasis

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

Playas are formed when a lake dries up, leaving behind a flat, dry surface.

Multiple choice

What is a wadi?

  1. A dry riverbed

  2. A type of sand dune

  3. A desert oasis

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

Wadis are formed when water flows through a desert during a rainstorm, creating a temporary riverbed.

Multiple choice

What is a pediment?

  1. A gently sloping plain at the base of a mountain

  2. A type of sand dune

  3. A desert oasis

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

Pediments are formed when wind and water erode the base of a mountain, creating a gently sloping plain.

Multiple choice

Which of the following is a type of desert landform?

  1. Sand dune

  2. Playa

  3. Desert pavement

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

Sand dunes, playas, and desert pavements are all types of desert landforms that are formed by the erosion of wind and water.

Multiple choice

  1. Longshore drift

  2. Beach nourishment

  3. Rip currents

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

Longshore drift is the process by which waves erode and transport sediment along a coastline, typically in a zigzag pattern.

Multiple choice
