Correct option is C
The correct matching is:
· A. Perihelion – II: Earth comes closer to the Sun.
· B. Aphelion – III: Earth little farther from the Sun.
· C. Albedo – I: Reflection Coefficient.
· D. Isotherms – IV: Shows the horizontal distribution of temperature.
Explanation:
1. Perihelion (A):
· Refers to the point in Earth's orbit where it is closest to the Sun.
· Occurs around January 3rd each year.
2. Aphelion (B):
· Refers to the point in Earth's orbit where it is farthest from the Sun.
· Occurs around July 4th each year.
3. Albedo (C):
· Represents the reflection coefficient or the percentage of incoming solar radiation reflected by a surface.
· High albedo surfaces (e.g., ice and snow) reflect more light.
4. Isotherms (D):
· Lines on a map that connect points of equal temperature.
· Useful for displaying horizontal temperature distributions across regions.
Information Booster:
1. Perihelion increases solar energy received by Earth in January.
2. Aphelion reduces solar energy received by Earth in July.
3. Albedo affects Earth's climate by determining how much solar radiation is reflected.
4. Isotherms help in weather forecasting and climate analysis.
5. The Earth-Sun distance varies due to the elliptical shape of Earth's orbit.
6. Changes in Earth's albedo can influence global warming and cooling trends.
Additional Knowledge:
· Perihelion (A):
· Closest distance to the Sun: Approximately 147 million km.
· Results in slightly higher solar radiation for the Southern Hemisphere.
· Aphelion (B):
· Farthest distance from the Sun: Approximately 152 million km.
· Results in slightly lower solar radiation for the Northern Hemisphere.
· Albedo (C):
· Earth's average albedo is about 30%.
· High albedo examples: Snow (80-90%), Clouds (50-70%).
· Isotherms (D):
· Used in meteorology and climate studies.
· Help visualize temperature variations across geographical regions.
Key Points:
1. Earth’s orbit affects seasonal temperature variations.
2. Albedo influences climate and energy balance.
3. Isotherms are essential tools in climate mapping.
4. Perihelion and aphelion mark Earth's varying distance from the Sun.
