1. The isotherms deviate to the north over the ocean and to the south over the continent.
2. The presence of cold ocean currents, Gulf Stream and North Atlantic Drift make the North Atlantic Ocean colder and the isotherms bend towards the north.
Select the answer using the code given below :
(a). 1 only
(b). 2 only
(c). Both 1 and 2
(d). Neither 1 nor 2
Explanation:
In January, the northern hemisphere experiences winter. Land cools down faster than water. So, temperatures over land are lower compared to oceans. This leads to a southward shift of isotherms over land and a northward shift over oceans.
The Gulf Stream and North Atlantic Drift are warm ocean currents. They actually warm the North Atlantic Ocean, causing isotherms to bend northward in that region.
Therefore, the correct answer is (a).
