Question

Using Figure 12 and your own knowledge, explain how different landforms may be created by the
transport and deposition of sediment along the coast.

Answer 1

Answer:

Deposition occurs when the sea has less energy ,eg in sheltered bays. Material that has been eroded from the coast is  transported  by the sea and later put down. Longshore drift is a process of transportation that shifts eroded material along the coastline. Swash carries sediment up the beach at an angle.

Explanation:

Answer 2

The formation of Landforms by transport and deposition of sediment along the coast.

Explanation:

• The formation of sandspit is due to longshore drift.
• Waves carry eroded materials to the shore due to traction and saltation.
• The debris is deposited in a zigzag pattern along the coast by the waves.
• The material is swashed along the coast at an angle before being backwashed at a right angle down the beach by the waves.
• The prevailing wind determines the swash angle. Furthermore, the prevailing wind determines the shape and growth of the sand spits.
• The deposition of sand, shingles, and pebbles on beaches is generated by wave activity and longshore drifts.
• Beaches that are gently sloping are created by strong damaging waves that backwash more debris away from the beach than up the beach.
• Waves that are constructive bring more material to the shore than they wash away, resulting in steeply sloping beaches.
