Answer 1

The correct option is C Ocean currents

Ocean currents are streams of water flowing constantly on the ocean surface in definite directions. Ocean currents are like river flow in oceans. They play a very important role in regulation of climate on the Earth.

Tides are periodic movements of ocean water due to the Moon and Sun’s gravity. The alternate rise and fall of water on the ocean surface is called waves.
