North Atlantic Drift:

The North Atlantic Drift, also known as the North Atlantic Current, is an extension of the Gulf Stream. It carries warm water from the Gulf of Mexico across the Atlantic Ocean towards Northwestern Europe. The North Atlantic Drift significantly affects the climate of countries such as the United Kingdom, Ireland, and Scandinavia

California Current:

The California Current is a cold, eastern boundary current that flows southward along the western coast of North America. It originates from the subarctic Pacific Ocean and travels southward, influencing the climate of California and the surrounding regions.

Understanding the major ocean currents of the world is crucial for comprehending global climate patterns, marine life distribution, and the interconnection between different regions.
