• Solution

• Traction

Which type of transportation involves larger sediment being rolled along the seabed or riverbed?

• Solution

• Saltation

• Traction

• Suspension

What is the transportation process called where sediment is repeatedly picked up and dropped by waves or river flow, bouncing it along the bed?

• Traction

• Saltation

• Suspension

• Longshore drift

Which type of transportation involves smaller sediment particles being carried by waves or river flow?

• Traction

• Saltation

• Suspension

• Longshore drift

What is the term for the transportation process where material is moved along a beach by wave action, with swash moving up the beach at an angle and backwash retreating down the beach due to gravity?

• Traction

• Saltation
