Question

You and a friend set up an umbrella and chairs at a beach. Your friend then goes into the surf zone to play Frisbee with another person. Several minutes later, your friend looks back toward the beach and is surprised to see that she is no longer near where the umbrella and chairs were set up. Although she is still in the surf zone, she is 30 or 40 meters away from where she started. How would you explain to your friend why she moved along the shore?

Answer 1

Answer:

Your friend moved along the shore due to ; The swash effect and the Backwash effect

Your friend moved along the shore due to ; The swash effect and the Backwash effectSwash effect is caused by the upsurge of water up along the slopping front of the beach and this same upsurge in water moves back into the beach in what is known as the backwash effect hence the movement of your friend form where they were in the surf zone to another position still within the surface zone is caused by the BACKWASH EFFECT
