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.

∙ 10y agoThe movement of sand depends on the angle at which the waves hit the shore at an angle.the waves wash sand onto the shore at the same angle that the waves are moving .
If someone reads this YOUR DUMB -.- you should at least try to do your home work duhh

What transports most of the sediment in the beach environment?
Longshore Currents transport most sediment along the shore of beaches, according to my science book. .
An accumulation of sediment deposited by waves and longshore drift along a bay is called a?
wrack is the debris along the shoreline
Why have gryones been built along many coasts?
To stop the effects of longshore drift whereby beach sediment of sand and shingle are moved along the coastline. The reason for stopping this is because sand acts as a great form of natural defense against erosion of coastlines.
What is a movement of sediments along a beach shore called?
longshore drift
How are sand and gravel particles moved along the ocean bottom?
Sand is gradually carried down the beach by Longshore Drift.

What transports most of the sediment in beach?
Longshore Currents transport most sediment along the shore of beaches, according to my science book. .
What creates longshore current?
Longshore currents create beaches.
Is longshore drift the cause or the effect of a longshore current explain?
effect. longshore drift is the combined effect of sediments moved by longshore currents and and beach drift. longshore currents are ocean currents that flow parallel to the coast while beach drift is the resultant zigzag movement along the beach.

What is the relationship between longshore currents and sandbars?
longshore currents for example ,often deposit sand along shorelines,the sand builds up to form sandbars
An accumulation of sediment deposited by waves and longshore drift along a bay is called a?
wrack is the debris along the shoreline
What is longshore drift?
How sand and other materials are carried parallel to the shore by the waves. The waves approach the beach at an angle.Longshore drift is the movement of sediment along the coastline.Longshore drift is the transport of erosion sands along a shoreline by the current flowing along it.
Why is a longshore drift a problem at Dawlish Warren?
Longshore drift moves sediment along the beach which lengthens the sand spit. Groynes have been put in place to try and reduce the effects of longshore drift.
What is the zig zag movement of sand along the shoreline?
Longshore drift is the process that moves sand and other sediments along a shoreline. It is also referred to as longshore transport or littoral drift.
How are spits made?
Spits are narrow, elongated ridges of sand or gravel that form due to the movement of sediment by longshore drift along a coastline. They typically extend from the shoreline into a body of water, often forming at the mouth of a bay or estuary where sediment is deposited by waves and currents. Over time, spits can grow and change shape as sediment is added to one end and eroded from the other.
How are spit and trombolo alike?
When you have longshore currents that transport the sand along a beach, they can create a spit where there is a projection along the coast. Spits develop from a wave train that is oblique to the shore causeing the sand to be deposited longitudinally projecting from the protruding point on the shore. They are attached to the shore at one end. Trombolos can occur when currents create a bar from the beach out of a large quantity of oceanic sediment called a stack. A trombolo is somewhat like a large ripple created from the stack accumulation. The are alike in a general sense of oceanic deposits but are very different in that the currents are oblique (tombolo) and more perpindicular (spit).
