The Element _______________ makes up 55% of the salts found in seawater.
Chlorine
The abundant nutrients associated with ocean _______________________ support highly productive plant and animal marine communities.
Upwellings
When continental borders are found to the left and right of an ocean body, the ocean currents in this type of basin develop a closed circular flow pattern known as a

Gyre
A _________________ refers to the cyclic rise and fall of seawater seen on our planet's oceans.
Tide
__________________ tides occur every 14-15 days during full and new Moons. These tides occur when the gravitational attraction of the moon is aligned with the Sun's gravity.
Spring
_____________________ tides occur during the first and last quarter of the Moon. They form when the gravitational pull of the Moon and Sun are at right angles to each other.
