Long shore currents form when waves approach the shoreline at an angle, causing the water and sediment to move parallel to the shore. This movement is a result of the wave's swash and backwash, creating a current that flows along the coastline. Long shore currents are influenced by wave direction, wave energy, and the shape of the coastline.

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.
Is longshore drift the cause or effect of a longshore current?
Longshore drift is the process of sediment moving along a beach due to wave action. It is driven by the longshore current, which is a current that flows parallel to the shoreline. Therefore, longshore drift is the result or effect of a longshore current.
Why don't longshore currents form in places were waves hit the shore head -on?
Longshore currents are driven by the angle at which waves approach the shore. When waves hit the shore head-on, rather than at an angle, there is no net transport of water along the shoreline to generate a longshore current. The wave energy is dissipated directly onto the shore, preventing the development of a longshore current.
How does a rip current form?
A rip current forms when waves push water towards the shore, causing it to flow back out to sea in a narrow and fast-moving channel. This can occur due to various factors, such as sandbars or underwater topography that funnels the water outwards. Rip currents can be dangerous for swimmers as they pull them away from the shore.
What effect does a long shore current have?
A long shore current can transport sediment along the coastline, causing erosion in some areas and deposition in others. It can also impact beach morphology, influencing the shape and size of beaches. Additionally, longshore currents can create hazardous swimming conditions by generating strong rip currents.
What is a long shore current?
A long shore current is sometimes flows along the shore and it also pull people away from the place where they entered the water

How does a long shore current affect the shore?
It erodes the sand then forms a sandbar and moves the sand down the beach
Why does sand long shore current flows towards the equator?
Coriolis effect
Why don't long-shore currents form in places where waves hit the shore head on?
Long-shore currents are generated when waves approach the coast at an angle, causing water to move parallel to the shore. When waves hit the shore head on, there is less tendency for water to move laterally along the coast, resulting in weaker or non-existent long-shore currents.
Why don't longshore currents form in places where waves hit the shore head-on?
Long-shore currents don't form in places where waves hit the shore head-on because the sand is moving in a zigzag pattern, making it at an angle.
Why don't longshore currents form in places were waves hit the shore head -on?
Longshore currents are driven by the angle at which waves approach the shore. When waves hit the shore head-on, rather than at an angle, there is no net transport of water along the shoreline to generate a longshore current. The wave energy is dissipated directly onto the shore, preventing the development of a longshore current.

When waves from the southwest strike a beach that runs east and west the direction of the long shore current will be?
The long shore current will typically flow parallel to the beach in a northeast or southeast direction following the direction of the incoming waves from the southwest. This current is generated as the waves push water along the shoreline, causing a movement of water in the same direction as the wave approach.
What do you do if your in a rip current?
Swim parallel to the ocean shore until clear of the current
