Answer: (a) 1 only
Topic: Geography – Temperature
Explanation: In January the isotherms deviate to the north over the ocean and to the south over the continent. This can be seen on the North Atlantic Ocean. The presence of warm ocean currents, Gulf Stream and North Atlantic drift, make the Northern Atlantic Ocean warmer and the isotherms bend towards the north. Over the land the temperature decreases sharply and the isotherms bend towards south in Europe.
Statement 2 is false as it is warm ocean currents and not cold ocean currents. Check NCERT chapter.
