What makes the isotherms run zigzag over continental areas?
Advertisements
उत्तर
- The air over the continental areas gets heated and cools faster than that over the oceans.
- The temperature in the continental areas changes faster as compared to the temperature over the water bodies.
- Due to this, the isotherm line deviates to a large extent while moving from the oceans to the land.
Hence, the isotherms run zigzag over the continental areas.
