How do waves erode coastlines? check all that apply. back-and-forth movement loosens sediment and rock. large rocks are picked up and deposited in new areas. continuous impacts loosen sediment and rock. loose sediment is picked up and blown to other locations. sediments scrape against one another and wear away surfaces.

Wave erodes coastline by different ways. If there are loose sediment at coastline, waves picked them up and blown to other locations. Continuous impacts also loosen sediment and rock. If the rock at coastline contains sand particles it acts like a abrasive material which cause scrapping of rock resulting into wear away surfaces. There are four type of erosion caused by waves:

When the waves strikes at cliff, water entrained into cracks causing them opening wide. This type of erosion is called hydraulic erosion. If the cliff contains sand particles, they acts like abrasive material, which cause erosion. This type of erosion is called Abrasion. When the waves containing rocky particles strikes the cliff, the impact cause breaking of rock. This type of erosion is called Attrition. When a rock contain salt or other soluble material, it dissolve in water. This type of erosion is called Solution.

Answer

Waves erode the coastline through;

• Back and forth movements that loosens sediments and rock

• Continuous impacts loosen sediment and rock

• Sediments scrape against one another and wear away

Hope i helped :D
