How do long shore currents more sand?
Longshore currents move sand along the coast by carrying it parallel to the shoreline. As waves approach the shore at an angle, they generate a current that moves sediments in a zigzag pattern. This process helps to redistribute sand along the coastline.
How does a long shore current affect the shore?
It erodes the sand then forms a sandbar and moves the sand down the beach
What type of erosion could move sand along the shoreline?
Longshore drift is a type of erosion that moves sand along the shoreline. This process occurs when waves approach the shore at an angle, carrying and depositing sediment in a zigzag pattern along the coastline.
What words describes the motion of a grain of sand as it moves along?
A grain of sand can be described as rolling, sliding, or shifting as it moves along a surface.
Sand that accumulates in a long pile along the shore?
sandbar
What moves sand along the beach?
The wind.
What doesn't affect the movement of sediment along the shore?
size of sand grains
The movement of sand along the beach is called?
long-shore drift
Where does an undertow take sand and other particles from the shore?
An undertow typically moves sand and other particles away from the shore and into deeper water. The force of the undertow can gradually erode the beach as it carries sediment offshore.
Near shore larger sand and gravel particles are moved along the ocean bottom by?
turbulence
Along what does longshore currents transport sediment?
Waves approach a shore obliquely (at an angle) due to the effects or the tides, currents the coriolis effect etc. and then retreat due to gravity straight. A good analogue is to roll a marble up a slope at an angle; it will fall more linearly on its return. Hope this helps.
