What is gravity?
-A force that attracts a body toward the center of Earth
Why is a tidal force important?
-Tides cause changes in the depth of the sea, and also produce oscillating currents known as tidal streams, making prediction of tides important for coastal navigation.

Since the Earth rotates through two tidal “bulges” every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes. High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.

Tides are caused by the gravitational interaction between the Earth and the Moon.
