Products of Volcanic Eruptions
Question
Which of the following is/are correct inference/inferences from isothermal maps in the month of January?
- 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.
Options
1 only
2 only
Both 1 and 2
Neither 1 nor 2
Explanation
Statement 1 is correct for the Northern Hemisphere; water retains heat better than land, so oceans are warmer in January, causing isotherms to deviate poleward (north) over oceans and equatorward (south) over colder continents. Statement 2 is incorrect because the Gulf Stream and North Atlantic Drift are warm ocean currents, not cold currents, although they do cause the northward bend.
Answer: (a).
