What is coastal erosion and deposition?
Most shorelines contain sand. The motion of waves helps to shape shorelines. During erosion, waves remove sand from shorelines. During deposition, waves add sand to shorelines.
What is coastal erosion kid definition?
Coastal erosion is the removal of beaches or sand dunes by tidal currents, waves, or drainage. Waves that are caused by storms and strong winds cause coastal erosion.
What is the difference between coastal erosion and coastal deposition?
In general, erosional coasts are those with little or no sediment, whereas depositional coasts are characterized by abundant sediment accumulation over the long term. Both temporal and geographic variations may occur in each of these coastal types. Erosional coasts typically exhibit high relief and rugged topography.
How do you explain erosion to a child?
Water, wind, and other natural forces cause rocks and earth to wear away. These forces also move bits of rock and earth to new places. This movement changes the shape of the land. These processes are called erosion.
What is a coastal deposition?
When the sea loses energy, it drops the sand, rock particles and pebbles it has been carrying. This is called deposition. Deposition happens when the swash is stronger than the backwash and is associated with constructive waves.
What are the 4 processes of coastal erosion?
Destructive waves erode through four main processes; Hydraulic Action, Compression, Abrasion and Attrition. Image credit: Jeff Hansen, U.S. Geological Survey. Hydraulic Action is the sheer force of water crashing against the coastline causing material to be dislodged and carried away by the sea.
What is the meaning of deposition in geography?
Deposition is the laying down of sediment carried by wind, flowing water, the sea or ice. Sediment can be transported as pebbles, sand and mud, or as salts dissolved in water.

What is erosion and deposition in geography?
Definition. Erosion. Erosion is defined as wearing away of rock along the coastline. Deposition. Deposition is a process in which sediments, knocked rock pieces, and soil are carried by wind, gravity and water and deposited in a new location to a landform or land mass.

What is erosion in geography?
Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.
