Geomorphic Processes Questions

Multiple choice

Which of the following factors is NOT a major control on sediment transport in a river?

  1. Water discharge

  2. Sediment supply

  3. Channel slope

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

Vegetation is not a major control on sediment transport in a river, as it is a relatively minor factor compared to water discharge, sediment supply, and channel slope. Vegetation can influence sediment transport to some extent, but it is not a primary control.

Multiple choice

The term 'alluvial' refers to:

  1. Sediment deposited by a river

  2. Sediment deposited by a glacier

  3. Sediment deposited by a wind

  4. Sediment deposited by a marine environment
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Alluvial refers to sediment deposited by a river. Glacial deposits are referred to as till, wind-blown deposits are referred to as loess, and marine deposits are referred to as marine sediments.

Multiple choice

The process by which a river channel migrates laterally over time is known as:

  1. Channel migration

  2. Avulsion

  3. Meandering

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

Channel migration is the process by which a river channel migrates laterally over time. Avulsion is the process by which a river abandons its current channel and creates a new one, meandering is a type of river channel pattern characterized by sinuous bends, and braiding is a type of river channel pattern characterized by multiple channels separated by sediment bars.

Multiple choice

Which of the following is NOT a type of riverine landform?

  1. Floodplain

  2. Meander

  3. Oxbow lake

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

Sand dune is not a type of riverine landform, as it is a landform associated with wind-blown sediment. Floodplains, meanders, and oxbow lakes are all types of riverine landforms.

Multiple choice

The process by which a river abandons its current channel and creates a new one is known as:

  1. Avulsion

  2. Channel migration

  3. Meandering

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

Avulsion is the process by which a river abandons its current channel and creates a new one. Channel migration is the process by which a river channel migrates laterally over time, meandering is a type of river channel pattern characterized by sinuous bends, and braiding is a type of river channel pattern characterized by multiple channels separated by sediment bars.

Multiple choice

Which of the following is NOT a factor that influences river channel evolution?

  1. Water discharge

  2. Sediment supply

  3. Channel slope

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

Climate is not a direct factor that influences river channel evolution, as it primarily affects the hydrology and sediment supply of a river. Water discharge, sediment supply, and channel slope are all direct factors that influence river channel evolution.

Multiple choice

Which of the following is NOT a type of sediment deposit found in a river channel?

  1. Point bar

  2. Riffle

  3. Pool

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

Sand dune is not a type of sediment deposit found in a river channel, as it is a landform associated with wind-blown sediment. Point bar, riffle, and pool are all types of sediment deposits found in a river channel.

Multiple choice

The process by which sediment is deposited on the riverbed or banks is known as:

  1. Deposition

  2. Erosion

  3. Sediment transport

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

Deposition is the process by which sediment is deposited on the riverbed or banks. Erosion is the process by which sediment is detached from the riverbed or banks, sediment transport is the process by which sediment is moved downstream in a river, and channel migration is the process by which the river channel moves laterally over time.

Multiple choice

The term 'braided river' refers to:

  1. A river with a single, meandering channel

  2. A river with multiple channels separated by sediment bars

  3. A river with a straight channel

  4. A river with a wide floodplain
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Braided river refers to a river with multiple channels separated by sediment bars.

Multiple choice

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

  1. Canyon

  2. Gorge

  3. Valley

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

Sand dune is not a type of riverine landform created by erosion, as it is a landform associated with wind-blown sediment. Canyon, gorge, and valley are all types of riverine landforms created by erosion.

Multiple choice

What is the primary cause of soil erosion?

  1. Wind

  2. Water

  3. Gravity

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

Soil erosion can be caused by wind, water, gravity, or a combination of these factors.

Multiple choice

What is the process by which sediment is deposited on a floodplain during flooding called?

  1. Aggradation

  2. Degradation

  3. Erosion

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

Aggradation is the process by which sediment is deposited on a floodplain during flooding. This process helps to build up the elevation of the floodplain over time.

Multiple choice

What is the term used to describe the highest level of water reached during a flood?

  1. Flood stage

  2. Crest

  3. Base flow

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

The crest of a flood is the highest level of water reached during a flood event.

Multiple choice

What is the term used to describe the process by which a river channel widens and deepens over time?

  1. Erosion

  2. Transportation

  3. Deposition

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

Lateral migration is the process by which a river channel widens and deepens over time as the river meanders and erodes its banks.

Multiple choice

What is the term used to describe the process by which water infiltrates the ground and becomes groundwater?

  1. Infiltration

  2. Percolation

  3. Evaporation

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

Infiltration is the process by which water infiltrates the ground and becomes groundwater.
