Question

State three effects of ocean currents on trade and commerce.
i will mark the fastest and correct answer brainiest

Answer 1

Answer:

Currents help ships to sail if they follow the directions of the currents. Many warm currents keep the ports of Europe ice free even during the winters. This helps in trade and commerce. The ships face danger due to the fogs caused by the meeting of the warm currents with the cold currents

Answer 2

Explanation:

What is Ocean Current :

An ocean current is a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences.

Effect On Trade And Commerce

• Ocean Currents help ships to sail if they follow the directions of the currents.
• Many warm currents keep the ports of Europe ice free even during the winters. This helps in trade and commerce.
• The mixing of warm and cold currents help to replenish the oxygen and favour the growth of planktons, the primary food for the fish population. The best fishing grounds of the world exist mainly in these mixing zones. This gives a great opportunity to the fishermen.
• The North Atlantic Current – popularly known as the Gulf Stream – warms Norway and Northern Europe. But if its waters flowed smoothly north along the Norwegian coastline, the current would deliver far less warmth to Norway. It is the chaos of the seas that warms the country, researchers have discovered.
• The ships face danger due to the fogs caused by the meeting of the warm currents with the cold currents.
