Question

how do ocean currents affect the climate?class 5 level

Answer 1

Ocean currents influence the climate and economic activities of coastal areas. Winds passing over warm and cold currents modify their temperature accordingly.
When these winds blow over the coastal lands, they modify the temperatures therefore, making the lands comparatively warmer or colder.

Warm currents melt dangerous icebergs, which they encounter, thus reducing danger to ships whereas cold currents often carry icebergs to the lower latitudes.
