Basics
How many high tides occur each day?
2
This term describes the swelling and receding of the ocean on the shore
What are tides
Which organism is commonly found attached to rocks in tide pools?
What are Barnacles
What controls tide movement?
What is the moons gravitational pull
During extended low tides, organisms risk
What is drying out
This is the approximate number of hours between one high tide and the next
What is 12 hours (and 25 minutes)
This is the term for when the ocean reaches its highest point on earth
What is high tide
Sea stars and other tide-pool animals rely on this daily cycle of water
What are tides
This is the force from the moon that pulls on the side of Earths ocean
What is gravity
During low tide exposed organisms risk these hunters
What are predators
This term names the difference in height between high tide and low tide
What is tidal range
What is a neap tide?
When the sun and moon cancel each others gravity out
Tides help move nutrients around, which group of ocean producers benefit
What is algae
This body has a smaller but still important gravitational effect on tides
What is the sun
This is the term for the ever-changing tide-pool environment
What is the intertidal zone
What happens to tide pool when the tide goes out?
What is exposed to air
What is a spring tide?
when the sun and moons gravity is greater making the tides greater too
How do small creatures resist getting pulled back into the ocean during high tides?
What what are byssal threads
What angle are the sun and moon at during a spring tide?
what is 180
This factor dramatically changes in a tide pool between high and low tide
What is temperature
Which zone of the intertidal area is exposed to air for the longest amount of time?
What is low intertidal zone
This term describes the stretched, oval shape of Earth's oceans caused by gravity pulling one side and centrifugal force pulling the other
What is tidal bulge
Tides help distribute this
What is nutrients
This outward-pushing force is the opposite of centripetal force
What is centrifugal force
Tides help prevent this condition, when water sits still for too long and creates harmful algae buildup
What is (water) stagnation
