Answer 1

Ocean currents are the horizontal continuous flow of a mass of water from one place to another. Ocean currents involve the transfer of heat energy from heat surplus regions to heat deficit regions. As a result, the climate of the region in the vicinity to the ocean current is affected. In cold regions where warm ocean currents flow, the climate becomes warmer. For instance, the presence of warm water currents along with western Europe in winter ensures that ports do not freeze.
