Which statement describes what is happening at high tide?
a. the moon is revolving more quickly than the earth is rotating.
b. the moon’s gravity is dragging water away from the equator.
c. the moon’s gravity is pulling ocean water into a bulge.
d. the sun’s gravity pulls with more force than the moon’s gravity.

Option C, The moon’s gravity is pulling ocean water into a bulge

Explanation:

Tides occur in the sea or ocean due to the gravitational force of the moon. This gravitational force generates tidal force thereby causing bulging of water majorly at two sides i.e the closest and the farthest side of the moon.  

Earth crosses these bulges every day. A high tide occur when earth lies in any of the two bulging sides while it experiences a low tide when it do not lies in the bulging sides.  

Hence, option C is correct

The answer is actually C, The moon's gravity is pulling ocean water into a bulge.

the answer is b: 1.4 km/hr
