Both currents and tides are predictable patterns of movement in water

a. true

b. false

The statement is a true statement that is currents and tides are predictable patterns of movement in water.

Explanation: Tides are the movement of water up and down for an extended time duration, due to the effect of gravitational pull by sun or moon on water. While current shows the movement or disturbance in water surface. Currents due to tides are known as tidal currents. Hence by predicting the gravitational forces applying on water on earth, currents and tides can be predicted.

The given statement is true.

Both the tides and current are the predictable patterns of movement in the water. The tides are mediated by the gravitational force of the sun and the moon. They are signified by the movement of water up and down for an extended time duration.

When used in combination with water, the term current illustrates the motion of the water. Oceanic currents are mediated by numerous elements. One is the fall and rise of the tides. The tides produce a current in the oceans, in bays, near the shore, and estuaries along the coast. These are known as tidal currents. Tidal currents are the only kind of currents, which vary in a very definite pattern.
