Transcript of The Intertidal Zone :)

The Intertidal Zone By: Kori Frooman B3 Location: Zones & Descriptions High Intertidal Zone: Mid Intertidal Zone: Low Intertidal Zone: Spray Zone: The spray zone is underwater only during very high and rare tides and harsh storms. This zone is considered more land than water, but is wetted over and over by splashing waves and wind- blown spray. Animals: -Lichen The high intertidal zone is flooded during high tide that occurs 1 to 2 times a day. It is out of water between the tides for long periods of time. Animals: -Purple Shoreline Crab The mid intertidal zone is normally submerged, except for a short period of time during low tide. Animals: -Mussel Bed The low intertidal zone is always submerged, except for the lowest spring tides. Animals: -Anemones -Periwinkle Snails -Limpets -Lice -Isopods -Barnicles -Barnacles -Blue- Green Seaweed -Sea Urchin -Snail -Sea Stars -Anemones -Red Algae -Dungess Crab -Sea Star -Kelp Videos: Sources The intertidal zone is the area between low and high tide zones. It is also where land and sea meet. This zone is found along coastlines worldwide: along rocky shores or sandy beaches. Fun Facts: Salt levels in the intertidal zone are very high because salt water gets trapped in the rocks and crevices. Then the water evaporates leaving behind salt. Tide pools are formed in the intertidal zone at low tide. The animals in the intertidal zone are preyed on by many things: in the water, fish and sea animals, and out of the water, land animals (foxes, people, birds, and walruses). http://www.montereyinstitute.org/noaa/lesson10/l10la2.html

Tide Pools Coral Reefs Estuaries Bays Why is the intertidal zone so hard to live in? 1. Moisture: The intertidal zone is submerged at high tides and exposed at low tides. Organisms must adapt to both dry and wet climates. 2. Water Movement: The animals must adapt to harsh waves that can pull organisms out to sea if not fully adapted. 3. Temperature: The water temperature has a wide range. It can be below freezing all the way to scorching hot 4. Salinity: The intertidal zone water is much saltier than normal ocean water.
