A coastal current, parallel to the shores produced by wave refraction is called
A
Tidal current
B
Gulf stream
C
Tidal wave
D
None of the above
Explanation: 

Detailed explanation-1: -When a wave reaches a beach or coastline, it releases a burst of energy that generates a current, which runs parallel to the shoreline. This type of current is called a “longshore current.”

Detailed explanation-2: -Wave Refraction The shallow part of the wave “feels” the bottom first. This slows down the inshore part of the wave and makes the wave “bend.” This bending is called refraction. Most waves strike the shore at an angle. This creates longshore currents, which move roughly parallel to the shoreline.

Detailed explanation-3: -Longshore drift is also called longshore transport. It is the movement down the beach of the sediment in a zigzag pattern. The longshore current is responsible for this transport. By breaking at an angle, waves move sand and water the beach in a zigzag manner.

Detailed explanation-4: -This is called a longshore current. Wave uprush and backwash also move sand grains diagonally up and down the beach in the same direction as the longshore current. Large quantities of sediment can be moved along a coastline by these processes. Rip currents occur when waves have “piled up” water close to the shore.
