Weight Loss. If you want to lose weight, you will need to adjust your caloric intake accordingly. One pound of body weight is equal to 3,500 calories.

Lesson Summary. Let's review. Coastal erosion is the wearing away of coastal land or beaches and is mainly caused by the impact of waves. Waves do not typically strike the shore head on. Wave refraction is the bending of waves as they travel toward the shallow waters of the shore.
The four main types of coastal erosion are Abrasion, Hydraulic action, Corrosion and Attrition. 1  Abrasion / Corrosion-Where sand and shingle are picked up by waves and scrap along the coastline.2  Hydraulic Action-The pounding affect of water on the coastline during storms.
