What is a ridge of sand that runs parallel to the shore called?
A ridge of sand that runs parallel to the shore is called a sandbar. Sandbars are typically submerged or partially exposed at high tide and can be an important habitat for marine life.
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.
What are long sand ridges oriented at right angles to the wind?
Transverse dunes are long sand ridges that are oriented at right angles to the prevailing wind direction. They form when wind blows sand over a stationary object, like a plant or rock, causing the sand to accumulate into a ridge perpendicular to the wind direction.
What are four coastal features that are created by wave deposition?
Spits, tombolos, barrier islands, and beach berms are coastal features created by wave deposition. Spits are elongated ridges of sand or shingle extending from the mainland into the sea, tombolos connect an island to the mainland, barrier islands are long, narrow offshore deposits of sand running parallel to the coast, and beach berms are elevated ridges of sand along the backshore of a beach.
How does a long-shore current change a beach?
A long-shore current can change a beach by transporting sand along the coastline. This can result in the erosion of some areas while causing deposition of sand in others. Over time, the beach's shape and size may be altered due to the long-shore current's influence.
What are the barrier of beaches?
sand ridges that rise slightly above the surface of the sea and run roughly parallel to the shore, from which it is separated by a lagoon.
What are long sand ridges oriented nearly parallel to the prevailing wind called?
Long sand ridges oriented nearly parallel to the prevailing wind are called sand dunes. They are formed by the deposition of sand carried by the wind and are common in deserts and coastal areas.
What is the movement of sand parallel to the shore?
np
What is a ridge of sand that runs parallel to the shore called?

The movement of sand parallel to the shore?
longshore drift
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 is a barrier built at a right angle to the beach to trap sand that is moving parallel to the shore?
groins
What is called a barrier built at a right angle to the beach for the purpose of trapping sand that is moving parallel to the shore?
groins
Sand that accumulates in a long pile along the shore?
sandbar
Long winding ridges of sand and gravel deposited by mouth water is called what?
Moraine.
Why does sand long shore current flows towards the equator?
Coriolis effect
Along what does longshore currents transport sediment?
Longshore currents transport sediment along the coastline parallel to the shore. These currents are driven by the waves hitting the coast at an angle, causing sediment to move in a zig-zag pattern along the shoreline.
