Geomorphic Processes Questions

Multiple choice

What is the term for the process by which sediment is deposited on a coral reef?

  1. Erosion

  2. Deposition

  3. Accretion

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

Reef formation is the process by which sediment is deposited on a coral reef. This occurs when sediment is trapped by the reef's structure and gradually builds up over time.

Multiple choice

What is the term for the process by which sediment is deposited on a beach?

  1. Erosion

  2. Deposition

  3. Accretion

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

Beach formation is the process by which sediment is deposited on a beach. This occurs when sediment is transported to the beach by waves and currents and gradually builds up over time.

  1. Erosion

  2. Deposition

  3. Accretion

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

Sandbar formation is the process by which sediment is deposited on a sandbar. This occurs when sediment is transported to the sandbar by waves and currents and gradually builds up over time.

  1. Erosion

  2. Deposition

  3. Accretion

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

Mudflat formation is the process by which sediment is deposited on a mudflat. This occurs when sediment is transported to the mudflat by waves and currents and gradually builds up over time.

Multiple choice

What is the term for the process by which sediment is deposited on a mangrove forest?

  1. Erosion

  2. Deposition

  3. Accretion

  4. Mangrove forest formation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Mangrove forest formation is the process by which sediment is deposited on a mangrove forest. This occurs when sediment is trapped by the forest's roots and gradually builds up over time.

Multiple choice

What is the term for the process by which sediment is deposited on a salt flat?

  1. Erosion

  2. Deposition

  3. Accretion

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

Salt flat formation is the process by which sediment is deposited on a salt flat. This occurs when sediment is transported to the salt flat by waves and currents and gradually builds up over time.

Multiple choice

What is the term used to describe the phenomenon of icebergs breaking off from glaciers or ice shelves in the polar regions?

  1. Calving

  2. Ablation

  3. Sublimation

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

Calving is the process by which large blocks of ice break off from glaciers or ice shelves, particularly in the polar regions. It is a natural process that contributes to the formation of icebergs.

Multiple choice

What is the term used to describe the process of melting ice and snow in the polar regions?

  1. Calving

  2. Ablation

  3. Sublimation

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

Ablation refers to the process of melting ice and snow in the polar regions. It occurs due to factors such as solar radiation, warm air temperatures, and wind, and contributes to the loss of ice mass in glaciers, ice sheets, and sea ice.

Multiple choice

What is the term used to describe the gradual sinking of a foundation due to the compression of the soil beneath it?

  1. Consolidation

  2. Settlement

  3. Heave

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

Settlement refers to the gradual downward movement of a foundation due to the compression of the soil beneath it over time.

Multiple choice

What is the term used to describe the phenomenon of the melting of glaciers and ice sheets?

  1. Glacial retreat

  2. Sea level rise

  3. Permafrost thaw

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

Glacial retreat is the term used to describe the phenomenon of the melting of glaciers and ice sheets, primarily due to rising global temperatures.

Multiple choice

What is the term used to describe the phenomenon of rising sea levels?

  1. Sea level rise

  2. Coastal erosion

  3. Ocean acidification

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

Sea level rise is the term used to describe the phenomenon of rising sea levels, primarily due to the thermal expansion of ocean water and the melting of glaciers and ice sheets.

Multiple choice

What is the term used to describe the phenomenon of the thawing of permafrost?

  1. Permafrost thaw

  2. Glacial retreat

  3. Sea level rise

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

Permafrost thaw is the term used to describe the phenomenon of the thawing of permafrost, which is frozen ground in polar and subpolar regions.

Multiple choice

What is the term used to describe the process of an iceberg breaking apart?

  1. Calving

  2. Melting

  3. Erosion

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

Calving is the process by which large pieces of ice break away from glaciers or ice shelves, forming icebergs.

Multiple choice

What is the term used to describe the process of icebergs melting and disintegrating?

  1. Calving

  2. Melting

  3. Erosion

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

Melting is the process by which icebergs gradually lose their mass and disintegrate due to exposure to warmer water and air temperatures.

Multiple choice

What is the term used to describe the microscopic mechanism by which a crack propagates through a material?

  1. Cleavage

  2. Tearing

  3. Shear

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

Cleavage is a microscopic mechanism of crack propagation in which the crack advances along specific crystallographic planes, resulting in a smooth and flat fracture surface.
