Which of the following is NOT a primary
Which of the following is NOT a primary factor affecting the variation of insolation on Earth?
निम्नलिखित में से कौन सा पृथ्वी पर सूर्यातप की भिन्नता को प्रभावित करने वाला प्राथमिक कारक नहीं है?
Detailed Solution & Logic
Presence of water bodies in an area/ किसी क्षेत्र में जल निकायों की उपस्थिति
🟢 Explanation
Insolation refers to the amount of solar radiation received by a given area on Earth. Its primary factors include:
-
Rotation of the Earth on its axis – affects day and night duration.
-
Transparency of the atmosphere – clouds, dust, and pollution can reduce insolation.
-
Angle of inclination of the Sun's rays – determines the intensity of sunlight at different latitudes and seasons.
Presence of water bodies, while it affects local climate and temperature, is not a primary factor affecting insolation, as insolation depends on solar geometry and atmospheric conditions, not local surface features.
🟢 व्याख्या
सूर्यातप (Insolation) उस क्षेत्र पर सूर्य से प्राप्त विकिरण की मात्रा है। इसके मुख्य प्रभावक हैं:
-
पृथ्वी का अपनी धुरी पर घूमना – दिन और रात की अवधि निर्धारित करता है।
-
वातावरण की पारदर्शिता – बादल, धूल और प्रदूषण सूर्या विकिरण को कम कर सकते हैं।
-
सूर्य की किरणों का झुकाव कोण – विभिन्न अक्षांशों और मौसमों में सूर्य की किरणों की तीव्रता निर्धारित करता है।
हालाँकि क्षेत्र में जल निकायों की उपस्थिति स्थानीय जलवायु और तापमान को प्रभावित कर सकती है, यह सूर्यातप की प्राथमिक भिन्नता को प्रभावित नहीं करती है।
⭐ Extra Facts / अतिरिक्त तथ्य
🔹 Insolation is measured in W/m² (watts per square meter).
🔹 Maximum insolation occurs at the equator due to the Sun being overhead.
🔹 Seasonal variation in insolation leads to climate and temperature differences across latitudes.
