Earth’s surface temperature is largely influenced by insolation....
Factors Influencing Insolation
Insolation, or incoming solar radiation, is a critical factor affecting Earth’s surface temperature. Several key factors influence insolation:
1. Rotation of Earth
- The Earth's rotation affects the distribution of sunlight across the planet.
- Day and night cycles influence temperature variations, impacting local climates.
2. Angle of Inclination of Sun Rays
- The angle at which sunlight strikes the Earth determines its intensity.
- Direct sunlight is more concentrated, resulting in higher temperatures, while oblique rays spread over a larger area, leading to cooler conditions.
3. Length of the Day
- The duration of daylight affects the total amount of insolation received.
- Longer days result in more sunlight, increasing temperatures, especially during summer months.
4. Transparency of the Atmosphere
- The atmosphere's clarity influences how much sunlight reaches the surface.
- Factors like clouds, pollution, and humidity can scatter and absorb sunlight, reducing insolation.
Conclusion
All four factors—rotation of Earth, angle of inclination of sun rays, length of the day, and transparency of the atmosphere—significantly influence insolation. Understanding these factors is essential for comprehending climate patterns and temperature variations across different regions. Therefore, the correct answer is option 'C', as it includes all the relevant influences on insolation.
