Answer to Question 1

A beach is a deposit of unconsolidated sediment extending landward from low tide to a change in
topography, such as a line of sand dunes, a sea cliff, or the point where permanent vegetation begins.
A beach includes a backshore that is covered with water only during storms or especially high tides;
berms, platforms in the backshore composed of sediment deposited by waves; a beach face, the sloping
area below a berm exposed to wave swash; and the foreshore, an area covered by water during high
tide but exposed during low tide.

Answer to Question 2

Water comes into shore from the ocean, moves parallel to the shore for a while, and then moves
seaward in a narrow surface current that flows through the breaker zone. If you are caught in one, do
not try to swim directly back to shore; it will not work. You must swim parallel to the shore for a short
distance to get out of the rip current, and then swim shoreward.
