  1. Pelagic sediment

  2. Terrigenous sediment

  3. Authigenic sediment

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

Terrigenous sediment is the type of sediment that is composed of material that has been transported from land to the sea. It includes sand, silt, and clay.

Multiple choice

What is the significance of sediment transport in the resilience of riverine environments?

  1. It increases the risk of flooding

  2. It reduces the diversity of aquatic habitats

  3. It contributes to the formation of sandbars and islands

  4. It disrupts the natural flow of water
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Sediment transport in riverine environments contributes to the formation of sandbars and islands, which provide important habitat for wildlife and help to maintain the diversity of aquatic ecosystems.
