... currents are when water approaches the coastline at an angle, a flow of water is generated that runs parallel to the coastline (this flow of water is known as the longshore current)
Longshore
31
Surf zone meaning
Area where waves break
32
Longshore currents definition
When waves approach the coastline at an angle, a flow of water is generated that runs parallel to the coastline (This generated flow of water is the longshore current)
33
Does a longshore current run parallel or perpendicular to the coastline
Parallel
