Tides, Tidal Pools And Coasts Flashcards
Describe why tides occur
They are caused by the gravitational forces exerted on the earth by the moon and the sun
How do you determine the tidal range
The difference between the high water and the low water
What is the difference between a spring tide and a neap tide

How many times do high tides occur and how many times do low tides occur in a day
2 and 2
How many times per month do spring tides occur and neap tides
They both occur 2 times a month
Define tidal pool
Rock depressions within the intertidal zone where pools of water collect
Describe life in a tidal pool
Where the ocean Mets land, the organisms adapt really well like crabs, limpets, snails
Name two organisms and their adaptations to live in high tide
Crabs and marine snails and they have thick tough outer coverings to slow evaporation
Name two organisms and their adaptations to live in low tide
Barnacles and mussels and they anchor themselves to the rocks and they also hold seawater in their closed shells to keep from drying out
What are some abiotic factors that all organisms that live in the tide pool or along the coasts have to deal with in order to survive
Temp and sunlight
What are the adaptations for shrimp
They use their walking legs to gather and grab food and they also have pincers and their arms and she’ll to protect themselves
Define coast
The land or area next to the ocean
What is the difference between a primary coast and a secondary coast
A primary coast are processes that occur on land and a secondary coast are processes that occur at sea
What are four examples of primary coasts
Delta, drowned river valley, fault coast, lava coast
