Question

With respect to isotherm, consider the following statements:

1. The Isotherms are lines joining places having equal temperature.

2. In January the isotherms deviate to the south over the Ocean and to the north over the continent in the northern hemisphere.

• A. 1 only
• B. 2 only
• C. 1 and 2
• D. none of these

Answer 1

Answer: (A)

1 only

Isotherms are imaginary lines joining places of equal temperature. For convenience, the temperature are reduced to sea level as if the places actually existed at sea level. The spacing of isotherms indicated the steepness of temperature change. Closely spaced isotherms indicated higher thermal gradient.
