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.

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. .


What transports most of the sediment in beach?

Longshore Currents transport most sediment along the shore of beaches, according to my science book. .


Are longshore currents parallel to the shoreline?

Yes, longshore currents flow parallel to the shoreline. They are influenced by the angle of incoming waves and play a significant role in the transport of sediment along coastlines.


When waves moves parallel with the shore?

When waves move parallel to the shore, they are known as longshore currents. These currents can transport sediment along the coastline, resulting in the formation of features like sandbars and spits. Additionally, longshore currents can affect the erosion and deposition of coastal areas.


What creates longshore current?

Longshore currents create beaches.


Ocean water that moves almost parallel to shore?

This phenomenon is known as longshore currents. They are caused by the movement of waves hitting the shoreline at an angle, creating a current that flows parallel to the coast. Longshore currents can transport sediment along the coastline, affecting beach erosion and deposition.


What currents can move sand from one place to another?

Longshore currents, rip currents, tidal currents, and wave action are some of the main currents that can move sand from one place to another along coastlines. These currents can transport sand along the shore or offshore, influencing beach erosion and sediment deposition in different areas.


When does lonshore drift occur?

Longshore drift generally occurs when waves approach the shoreline at an angle, creating a zig-zag pattern of sediment transport along the coast. This process is most common in areas with strong wave action and prevailing currents that move sediment along the shore.


What are currents within the surf zone that flow parallel to shore known as?

Currents within the surf zone that flow parallel to the shore are known as longshore currents. These currents are generated by waves approaching the shore at an angle, creating a flow of water along the coastline. Longshore currents can significantly influence sediment transport and beach erosion, shaping coastal landscapes over time. They often interact with rip currents, which flow seaward and can pose hazards to swimmers.


What effect will the small bay have on the longshore current and its transportation of sediment?

The small bay will likely interrupt the longshore current by causing it to bend around the bay. This may result in the deposition of sediment on the updrift side of the bay and erosion on the downdrift side. The bay can act as a sediment trap, reducing the sediment transport along the coast.


Is longshore drift the cause or the effect of a longshore?

Longshore drift is the effect of longshore current because the water moves a certain way and causes the sand to take shape.


Is longshore drift the cause or 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.
