Answer: Ability of atmospheric gases to trap heat
Explanation The greenhouse effect occurs when certain gases in t he atmosphere trap heat from the Sun . Key greenhouse gases include CO₂, CH₄ (methane), N₂O, and water vapor. These gases allow sunlight to enter but absorb and re-radiate infrared radiation back to Earth. This process warms the planet, making life possible.
مندرجہ ذیل میں سے کون سا حصہ فضا میں شامل نہیں ہے؟
Answer: Hydrosphere
Explanation The Earth’s atmosphere is divided into different layers ( Troposphere, Mesosphere, and Exosphere ). Hydrosphere refers to all water bodies on Earth. Therefore, Hydrosphere is not part of the atmosphere. Additional information : Troposphere : 0–12 km (weather layer) Stratosphere : 12–50 km Mesosphere : 50–85 km Thermosphere : 85–600 km Exosphere : 600 km and above Last verified on 21-04-2026
صاف آسمان کے نیلے رنگ کی وجہ کیا ہے؟
Answer: sSattering of light
