Salt weathering is a collective term used to describe the breakup of rocks by physical processes driven by salt-generated pressures within small rock voids; sandy or coarse-grained sedimentary and volcanic substrates are thought to be especially vulnerable ( Evans, 1970, Trenhaile, 1987 ). Depositional landforms are the visible evidence of processes that have deposited sediments or rocks after they were transported by flowing ice or water, wind or gravity.

Since an arch ocean is caused due to water and wind erosion on the weaker rock section, it is a destructive landform. In quiet water areas, such as bays, wave energy is dispersed, so sand is deposited. What is the ratio of the number of turns of the 50-turn electromagnet to the number of turns of the 25- Waves are either constructive or destructive: - Constructive waves create depositional landforms and occur when the swash of a wave is stronger than the backwash - Destructive waves create erosional landforms and occur when the backwash of a wave is stronger than the swash A mountain is made by a constructive force.

Waves are constructive forces that deposit sand and sediments on the coast slowly. If two waves add up to make a larger wave this is known as constructive interference and if they cancel out its destructive interference. Destructive waves generally contain a higher frequency, and with more waves that occur per minute, erosion is usually the end-product.

Coastal Landforms - A-Level Geography - Marked by Teachers.com These processes continually shape the Earth's surface, and generate the sediments that circulate in the Rock Cycle. It is also formed by a destructive force. Why are constructive forces so destructive? This leaves behind pillars of rock. Destructive waves generally contain a higher frequency, and with more waves that occur per minute, erosion is usually the end-product. Waves can be constructive or destructive.
