Marine and Coastal Processes
- MOHAMED ERSHAD NP Reg No: 2015255014
- Coastal processes occur where waves break on a shore, not only on ocean/sea coasts but also on lakes/ponds
- Waves Currents Still-water deposition Biological activity Tides Sea level rises
- Waves are usually caused by wind and controlled by wind speed. ...
How do coastal processes involve significant use of energy?
These processes involve significant use of energy for coastal processes to occur. Some of the main impacts that influence beach and marine areas involve deposition, erosion, and transportation. Transportation happens when tides and waves transfer pieces of material to different areas. Deposition occurs when tides and waves lose their energy ...
What are the two processes that occur along the coast?
The atmospheric processes include temperature, precipitation, and winds, while the major marine processes are waves and tides, together with water temperature and salinity. The coast also supports rich ecosystems, including salt marshes, mangroves, seagrass, and coral reefs.
How are coastal landforms created by coastal processes?
Coastal Processes Coastal Processes Coastal landforms are created by a wide variety of coastal processes, which vary depending on the process, the wave climate, beach morphology, geology, and human activity. This results in the two umbrella processes of erosion and accretion.
How do coastal areas change over time?
These processes involve different events that build-up, breakdown, and transport materials in these coastal zones. Waves, wind, and tides for example impact these coastal areas and change their landscapes through continuous processes that happen all year round.

What is meant by marine processes?
Marine processes are those associated with the action of waves. This includes erosion, transportation and deposition.
What is marine and coastal processes and hazards?
Marine and Coastal Processes Marine and Coastal Processes - Occurs when waves break on a shore, not only on ocean or sea coasts but also on lakes and ponds. • Coastal Erosion - Coastal Erosion is the wearing away of the land by the sea. This often involves destructive waves wearing away the coast.
Why is it important to study coastal and marine processes?
In general coastal studies are important to policy makers, allowing them to minimize the effects of marine pollution to ecologically sensitive zones along the shorelines.
What are the 3 marine processes?
The three principle marine processes that influence coasts are erosion, transportation and deposition.
Why is coastal process important?
Coastal processes shape the physical environment, providing habitat such as turtle or seabird nesting beaches, reefs, and mangrove forests or seagrass beds.

What are examples of coastal hazards?
Some of the hazards include movement of barrier islands, sea level rise, hurricanes, nor'easters, earthquakes, flooding, erosion, pollution and human development along the coast.
What can you do to lessen the effects of marine and coastal processes?

What is marine and coastal environment?
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Marine coastal ecosystems include many different types of marine habitats, such as estuaries and lagoons, salt marshes and mangrove forests, seagrass meadows and coral reefs, kelp forests and backwaters.
What are the 4 marine processes?
Constructive and Destructive waves strong swash (movement of water up the beach) and weak backwash (movement of water down the beach) eliptical orbit. low.
What is coastal and marine resources?
The coastal and marine environment is a major provider of goods and services, such as food, fossil fuels, construction materials, transport and recreation.
What is meant by marine erosion?
Erosion by moving seawater, the action of which is largely intensified by detritus carried by it.
What is the difference between marine and subaerial processes?
Cliffs are eroded at the coast through marine processes and subaerial processes. The difference between the two types of erosion is that marine processes occur at the waterline and the subaerial processes occur above it.
What are the 4 processes of marine 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 are the 4 processes of transportation?
TransportSolution - minerals are dissolved in the water and carried along in solution.Suspension - fine light material is carried along in the water.Saltation - small pebbles and stones are bounced along the river bed.Traction - large boulders and rocks are rolled along the river bed.
