Question

The main reason that the earth experiences the highest temperatures in the subtropics in the northern hemisphere rather than at the equator is:

विकल्प

• Subtropical areas tend to have less cloud cover than equatorial areas.

• Subtropical areas have longer day hours in the summer than the equatorial.

• Subtropical areas have an enhanced “greenhouse effect” compared to equatorial areas.

• Subtropical areas are nearer to the oceanic areas than the equatorial locations.

Answer 1

Subtropical areas tend to have less cloud cover than equatorial areas.

Explanation:

The Northern Hemisphere subtropics (20° to 35° latitude) often have greater maximum temperatures than the equator. The reason is: 

• Due to the Intertropical Convergence Zone, equatorial regions have thick clouds and frequent rains but more steady sun energy year-round.
• High-pressure zones like the subtropical highs bring clear skies and dry conditions to subtropical regions.
• With less cloud cover, the sun directly heats the surface, raising daytime temperatures even when yearly energy is lower than at the equator.
