Question : Which current is responsible for increase in the temperature of the western Europe ?
Option 1: Labrador current
Option 2: Gulf stream
Option 3: Canari current
Option 4: North Equatorial current
Correct Answer: North Equatorial current
Solution : The correct option is North Equatorial current
The North Equatorial circulation (NEC) is a warm current in the Atlantic Ocean that moves westward. It forms at the equator and travels at speeds of up to 2 metres per second. The trade winds, which are easterly winds that sweep over the ocean surface, drive the NEC. The North Atlantic Current transports warm water from the Caribbean Sea and the Gulf of Mexico to the North Atlantic Ocean. This warm water helps to moderate the climate of western Europe, making it warmer than it would be otherwise. The NEC also brings nutrients to the surface of the ocean, which supports a variety of marine life. Without the NEC, western Europe would be much colder. The average temperature in London, for example, would be about 10 degrees Celsius cooler.
