Which of the following is/are correct inference/inferences from isothermal maps in the month of January?.

Explanation

Understanding Isotherms and Their Behavior

Isotherms are lines on a map connecting points with the same temperature.
January is a winter month in the Northern Hemisphere.
Land and Water Heating Differences: Land heats up and cools down faster than water. This leads to significant temperature differences between continents and oceans in winter.

Statement 1: Correct

Statement 2: Incorrect

The Gulf Stream and North Atlantic Drift are warm ocean currents, not cold.
These currents bring warm water from the tropics towards Europe, making the North Atlantic relatively warmer in winter.
Isotherms bend northward over the North Atlantic due to these warm currents.

Conclusion: Only statement 1 is a correct inference from isothermal maps in January.
