What processes are responsible for destruction of life and loss of property in coastal areas?
A rise in sea level splits the bar into parts separated by water. What processes are responsible for destruction of life and loss of property in coastal areas? Waves.
Which of the following impacts on coastlines are commonly associated with hurricanes?
Wave damage – It occurs mostly during hurricanes and storms; erosion of land and hillsides collapses slopes and buildings into the water. Storm surge -Water may pile up in front of an approaching weather system, inundating low-lying areas along the coast.
Which of the following factors would cause sea level to fall quizlet?
Which of the following factors would cause sea level to fall? Periods of global glaciation trap water in land-based glaciers. You just studied 37 terms!
Which of the following is true about how coasts are affected from the water side quizlet?
Which of the following is true about how coasts are affected from the water side? Waves can erode, deposit, or simply transport sediment. All of these affect the appearance. All of these are correct.
Which of the following are causes of coastal erosion?
Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural.
Which of the following activity that causes coastal erosion?
Sand and Coral Mining, and Maintenance Dredging Coral mining and other means of spoiling the protective coral reefs, for example, fishing by the use of explosives or pollution, will also cause coastal erosion and beach degradation.
Which of the following can cause beach erosion?
Beach erosion is caused by waves and currents removing sand from the beach. The loss of sand causes the beach to become more shallow. Storm waves carry sand and deposits it at a sandbar. weather waves.
What causes beach erosion?
Beach erosion is usually caused by ocean currents and waves. The energy of the moving water pulls sand away from the shore. High winds speed up erosion. It is very common to see severe erosion after a hurricane or a strong storm.
What could cause sea level changes along a coastline quizlet?
A factor that can affect this is global warming. This happens because the increased heat changes the amount of ice stored on land as water, thus changing the sea levels. A rise in temperature will cause the ice caps to melt, and sea levels will rise, and vice versa.
What factors are currently causing the sea level to rise quizlet?
Sea level rise is caused primarily by two factors related to global warming: the added water from melting ice sheets and glaciers and the expansion of sea water as it warms.
How can climate influence the processes along coastal landscapes?
Key Points. Climate change threatens coastal areas, which are already stressed by human activity, pollution, invasive species, and storms. Sea level rise could erode and inundate coastal ecosystems and eliminate wetlands. Warmer and more acidic oceans are likely to disrupt coastal and marine ecosystems.
What are some possible influences of ocean currents on glaciation quizlet?
What are some possible influences of ocean currents on glaciation? Cold currents can cool the land allowing glaciers to form if there is sufficient precipitation. Cold currents can inhibit the growth of glaciers because they put less moisture into the atmosphere.
What causes coastal erosion quizlet?
Erosion can be caused by violent storm waves and hard stabilization structures. When deposition output exceeds input erosion happens. Continual global rise is sea level and extensive development of coastal areas will make coastal erosion more common.
What causes sand movement along coastlines?
Sand grains move along the shore and up and down beaches because of currents made by waves. Waves break when they reach shallow water, creating turbulence. This area is called the surf zone. When waves break, some of the force is turned into currents.
What causes sand erosion?
Beach erosion is usually caused by ocean currents and waves. The energy of the moving water pulls sand away from the shore. High winds speed up erosion. It is very common to see severe erosion after a hurricane or a strong storm.
What causes coastline erosion?
Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms.
What causes the decrease in beach sand?
Urbanization of watersheds traps sediment under hardened surfaces so it no longer flows into the ocean with rainwater run-off. The result is reduced sand supply to beaches and, consequently, loss of beach habitat.
What factors affect the rate of coastal erosion?
This simple diagram shows the factors that can affect coastal cliff erosion, including sea level rise, wave energy, coastal slope, beach width, beach height, and rock strength.
Which of the following factors can change sea level on a global scale quizlet?
There are a number of factors that impact sea-level change over different timescales: waves (seconds), tides (hours, days, weeks etc.), Weather (hours, days, weeks etc.) and Climate Change (over decades, centuries and millennia).
What are the 3 causes of sea level rise?
Most of the observed sea-level rise (about 3 mm per year) is coming from the meltwater of land-based ice sheets and mountain glaciers, which adds to the ocean's volume (about 2 mm per year combined), and from thermal expansion, or the ocean water's expansion as it warms (roughly 1 mm per year).
What factors are currently causing the sea level to rise?
The two major causes of global sea level rise are thermal expansion caused by warming of the ocean (since water expands as it warms) and increased melting of land-based ice, such as glaciers and ice sheets.
What factors influence coastal landforms?
Climate is an extremely important factor in the development of coastal landforms. The elements of climate include rainfall, temperature, and wind. Rainfall is important because it provides runoff in the form of streams and also is a factor in producing and transporting sediment to the coast.

What removes sand and other sediment from the ground?
Wind removes sand and other sediment from the ground by the process of deflation.
What is the main cause of coastal erosion?
What causes coastal erosion? Coastal erosion is typically driven by the action of waves and currents, but also by mass wasting processes on slopes, and subsidence (particularly on muddy coasts).
Why do beaches lose sand?
Often, they change drastically during the year, depending upon the frequency of storms. Ultimately, a beach erodes because the supply of sand to the beach can not keep up with the loss of sand to the sea. Most sand is transported from inland via rivers and streams.
How do beaches lose sand?
Permanent loss of sand occurs at the end of the littoral cell when it flows into a submarine canyon or, less frequently, when it accumulates on shore as part of a sand dune. The amount of sand available to beaches is the amount of sand flowing into the littoral cell minus the amount flowing out.
What are 3 main causes of beach erosion?
The main causes of beach erosion are as follows:
- Reduction in sediment supply from eroding cliffs.
- Reduction of fluvial sediment supply to the coast.
- Reduction of sediment supply from the sea floor.
- Reduction of sand supply from inland dunes.
- Submergence and increased wave attack.
