The 'Beaches are Moving' is a 1983 documentary produced by University of North Carolina Television (UNC-TV), a work of marine geologist Orrin. H. Pilkey Jr.
1. ‘The Beaches are Moving’ was produced in the state of North Carolina.
2. The subject of the video is North Carolina’s Barrier islands. It focuses on common processes and developments that are unique to the barrier island system.
Hence, the correct answer is option (D).
3. A barrier island never stands still. Net sand movement in the beach may be on shore or off shore depending on weather conditions. In a fair weather, net sand movement is onshore nudged by gentle wave action. During large storms, sand movement becomes rapid and net sand movement is offshore.
In most of the North Carolina coast, net transport direction of sand along the shoreline is from north to south. But there are few exceptions.
4. An ocean current that moves parallel to the shore is called long shore current. Total sand transported by long shore transport in North Carolina is 100,000 cubic yards per year.
The correct answer is option (B).
5. Inlet is a narrow band of water that goes from sea or lakes into the land or between islands. Tidal currents keep the inlets between islands open also interrupting the long shore current.
Hence, the correct answer is option (C).
6. About 15,000 years ago, glaciers were beginning to melt and sea levels were beginning to rise. Barrier islands were first formed 15,000 years ago when sea level was 300 feet lower than today.
Hence, the correct answer is option (D).
7. Islands are widened by direct frontal overwash of storm waves from the ocean side during storm. Overwash waves carries sand that gets deposited as fan-shaped masses called wash fans. Fan-shaped deposits of sand deposited during a storm are called overwash fans.
Hence, the correct answer is option (B).
