Sediment Transport and River Dynamics

The video tutorial covers the Earth Science Reference Table Page 6, focusing on the relationship between transported particle size and water velocity. It explains how to interpret the chart, solve related worksheet questions, and understand concepts like abrasion and sorting. The tutorial also discusses how rivers deposit sediments in a sorted manner as they lose energy entering the ocean.

What does the chart on page six of the Earth Science Reference Table illustrate?

• The relationship between water velocity and particle size.

• The depth of various rivers.

• The chemical composition of river water.

• The temperature variations in a stream.

If a river is moving at 100 cm/s, what size of particles can it carry?

• Pebbles

• Sand

• Boulders

• Clay

What is the stream velocity required to transport pebbles with a diameter of 0.2 cm?

• 50 cm/s

• 20 cm/s

• 10 cm/s

• 5 cm/s

What is the largest particle size a stream can transport at a velocity of 5 cm/s?

• Sand

• Clay

• Pebbles

• Cobbles

How does abrasion affect particles in a river?

• It smooths and rounds them over time.

• It makes them larger and more angular.

• It changes their color.

• It causes them to dissolve.

What is the process called when sediments become smoother and rounder as they move?

• Deposition

• Sedimentation

• Abrasion

• Erosion

What is the term for sediments that are grouped by similar size and shape?

• Erosion

• Weathering

• Sorting

• Deposition

Which type of sediment is deposited first when a river enters the ocean?

• Clay

• Silt

• Sand

• Boulders

What happens to the energy of a river as it enters the ocean?

• It increases.

• It fluctuates randomly.

• It decreases.

• It remains constant.

How are sediments deposited by a river typically sorted?

• By color

• By chemical composition

• By size and shape

• By age
