Answer: Ocean currents affect climate in the way that they regulate the temperature throughout the world and maintain their respective weather patterns.
Explanation: Ocean currents assist in transferring heat from portions of the earth to others. The warmer currents that settle tend to travel from the tropical parts to the poles, and the cold currents tend to bring the colder water from the poles back toward the equatorial regions. This exchange plays a crucial role in keeping the balance among the different parts.
The different ocean currents that exist throughout the world often distinctly influence the amount of moisture in the air. Fluctuations in this moisture determine the type of weather that occurs within a particular region. For example, warmer currents within regions increase the overall moisture, which leads to greater rates of rainfall and more humid conditions in the coastal areas.
Core ideas: temperature regulation and weather patterns.
