Fluvial processes

A word that describes processes and landforms that occur or found near/in a river is _______

Answer explanation

The term 'fluvial' specifically refers to processes and landforms associated with rivers. It encompasses the dynamics of river systems, including erosion, sediment transport, and deposition, making it the correct choice for this question.

What is fluvial transportation?

• Fluvial transportation refers to the movement of materials by wind.

• Fluvial transportation is the process of transporting goods by road.

• Fluvial transportation involves the use of trains to move materials.

• Fluvial transportation is the movement of materials by rivers and streams.

Answer explanation

Fluvial transportation specifically refers to the movement of materials by rivers and streams, distinguishing it from other forms of transport like wind, road, or rail.

The process of wearing away of rocks or land by wind, water or ice is called _______.

Answer explanation

The correct term for the process of wearing away rocks or land by natural forces like wind, water, or ice is 'erosion'. This term specifically describes the gradual removal and transport of soil and rock materials.

Which of the following is a type of river erosion where rocks and stones wear away the river bed and banks, like sandpaper?

• Solution

• Abrasion

• Attrition

• Hydraulic action

Answer explanation

Abrasion is the process where rocks and stones scrape against the river bed and banks, effectively wearing them down like sandpaper. This distinguishes it from attrition and hydraulic action, which involve different mechanisms of erosion.

What is the process called when the force of water breaks rock particles away from the river channel by the power of the water forcing open cracks in the river bed?

• Solution

• Attrition

• Hydraulic action

• Abrasion

Answer explanation

The process described is called hydraulic action. It occurs when the force of water enters cracks in the river bed, causing rock particles to break away due to pressure changes, unlike abrasion or attrition which involve different mechanisms.

Which river transportation method involves large boulders and rocks being rolled along the river bed, like a tractor?

• Suspension

• Saltation

• Traction

• Solution

Answer explanation

The correct answer is Traction, which describes the process where large boulders and rocks are rolled along the river bed, similar to how a tractor moves heavy objects. This method contrasts with Suspension and Saltation.

Which river transportation method involves smaller sediment being carried by the river's current and it's suspended in the river?

• Solution

• Saltation

• Suspension

• Traction

Answer explanation

The correct answer is 'Suspension' because it refers to the method where smaller sediment particles are carried and suspended in the river's current, unlike 'Saltation' and 'Traction', which involve different sediment transport methods.

What is the term for the process where dissolved minerals are carried by the river?

• Suspension

• Solution

• Saltation

• Traction

Answer explanation

The correct term for the process where dissolved minerals are carried by a river is 'Solution'. In this process, minerals are fully dissolved in the water, unlike 'Suspension', 'Saltation', or 'Traction', which involve solid particles.

Which of the following describes the bouncing movement of small pebbles and stones bounce along the river bed?

• Traction

• Solution

• Saltation

• Suspension

Answer explanation

Saltation describes the bouncing movement of small pebbles and stones along the river bed. In this process, particles are lifted and then fall back, creating a series of jumps, which is characteristic of saltation.

What is the name of the process where fine, light material is carried along in the water?

• Traction

• Suspension

• Saltation

• Solution

Answer explanation

The process where fine, light material is carried along in water is called suspension. In this process, particles remain distributed throughout the water, unlike traction, saltation, or solution, which involve different mechanisms of transport.
