New Terms Tides Tides Tidal range Tidal range Spring tides Spring tides Neap tides Neap tides Storm surge Storm surge

Ocean Tides The daily movement of ocean water that changes the level of the ocean’s surface The daily movement of ocean water that changes the level of the ocean’s surface

Tides are caused by 1.The gravitational attraction of the moon 2. “centrifugal force” as Earth and the moon orbit around a common center of balance

The Earth and Moon orbit around the “barycenter” (demonstration)

High Tides are bulges of ocean water that occur on the side of the Earth facing the moon and on the side opposite

Low Tides are the areas between the bulges. Tides change as the Earth rotates between the bulgesTides change

Tides occur 50 minutes later each day. Since the moon moves along in its orbit around the earth each day, the earth must rotate an additional 50 minutes to catch up.

Spring Tides Have a very large tidal range Have a very large tidal range Occur every 14 days during a full or new moon Occur every 14 days during a full or new moon

Spring Tides Are caused by the gravitational forces of the sun and moon pulling in the same directions (180 degrees) Sun Moon

Neap Tides Have small tidal ranges between high and low tides Occur every 14 days during 1st and 3rd quarter moons

Neap Tides PHASESofMoon.JPG PHASESofMoon.JPG Are caused by the gravitational forces of the sun and moon pulling at 90 degrees from each other Sun Moon

Tidal Range is the difference in height between the high tide and low tide.

At low tide in the Bay of Fundy, boats can be left setting on the bay bottom.

High tide arrives in 30 minutes in the Bay of Fundy, rising feet Tides of Nova Scotia Tides of Nova Scotia

The Bay of Fundy is in Canada near northeastern USA

" The Bay of Fundy is known for tidal bores. A tidal bore is the “face’ or edge of the incoming tide and travels about 13 mph. Surfing a tidal BoreSurfing a tidal Bore

When hurricanes or winter storms arrive during high tide, greater damage occurs.

Storm surges result when strong winds pile water along the shoreline.

Storm surges may raise sea level up to 18 feet above normal.

During Hurricane Andrew, an ocean- going tugboat was left high and dry by storm surge.

Along the Florida Keys, houses are built on stilts as a protection from storm surges.
