Q47.
Consider the following statements: Statement I: In January, in the Northern Hemisphere, the isotherms bend equatorward while crossing the landmasses, and poleward while crossing the oceans. Statement II: In January, the air over the oceans is warmer than that over the landmasses in the Northern Hemisphere. Which one of the following is correct in respect of the above statements?
Answer
A
Explanation
general the effect of the latitude on temperature is pronounced on the map, as the isotherms are parallel to the latitude. The deviation from general trend is more pronounced in January than July, especially in the northern hemisphere. In the hemisphere the land surface area is much than in the southern hemisphere. Hence, the of land mass and the ocean currents are well January the isotherms deviate to the north over the and to the south over the continent. This can be in the North Atlantic Ocean. The presence of warm currents, Gulf Stream and North Atlantic drift, the Northern Atlantic Ocean warmer and the bend towards the north. Over the land the decreases sharply and the bend towards south in Europe. Hence, Both I and Statement II are correct and Statement explains Statement I..Hence, Both Statement I and II are correct and Statement II explains I.
