How Natural Processes operate at a Coastal eographic Environment

A detailed Summary of How Natural Processes operate at a Coastal eographic Environment

How Natural Processes Operate at Coastal Geographic Environment.

Natural Processes are actions or events that have natural causes, which result in natural events. The three main coastal environment processes that operate at Muriwai are Coastal Erosion, Coastal Transportation and Coastal Deposition.

The elements that interact to produce natural processes are wind, waves and tides. Each phenomenon at Muriwai's coastal geographic environment has been produced by interaction.

Coastal Erosion is a process at Muriwai that gradually wears away the rock particles of the earth's surface, transporting them to another location. There are many types of processes that cause erosion at Muriwai such as wave erosion, wind erosion and wave refraction.

Thousands of years ago when sea levels dropped over years at the Southern end of Muriwai, the sedimentary rock and sandstone was exposed to the air. Rock from volcanic activity mixed with the sedimentary rock; this is called Breccia - a mixture of all rock. An example of this is at Maori Bay.

Coastal Erosion operates at different rates and different times. Limestone rock is eroded slower than sedimentary rock. The cliff at Muriwai made of sedimentary rock was eroded back to expose 'Fishe

Wind can move material by three processes - these are saltation, surface creep and suspension.

Longshore Drift is a transportational process, which determines the shape of Muriwai.
