Answer to Question 1A 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 2Water 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.
