Which of the following best explains the origin of coal and petroleum?
निम्नलिखित में से कौन-सा कोयला और पेट्रोलियम की उत्पत्ति को सबसे अच्छी तरह समझाता है?
Detailed Solution & Logic
Fossilisation of plants and animals under high temperature and pressure over millions of years/ मिलियन वर्षों तक उच्च तापमान और दाब में पादपों और जंतुओं का जीवाश्मीकरण
📘 Explanation
Coal and petroleum are fossil fuels formed from the remains of ancient plants and animals that lived millions of years ago.
Dead plants and animals were buried under layers of soil and sediments.
Over millions of years, high temperature and pressure acted on these remains.
In the absence of air, they slowly changed into coal, petroleum, and natural gas through a process called fossilisation.
Coal mainly formed from ancient forests, while petroleum and natural gas formed mostly from tiny marine organisms.
📗 व्याख्या
कोयला और पेट्रोलियम जीवाश्म ईंधन (Fossil fuels) हैं, जो करोड़ों वर्ष पहले जीवित पादपों और जंतुओं के अवशेषों से बने हैं।
मृत पादप और जंतु मिट्टी एवं तलछट की परतों के नीचे दब गए।
लाखों वर्षों तक उन पर उच्च तापमान और दाब का प्रभाव पड़ा।
वायु की अनुपस्थिति में ये अवशेष धीरे-धीरे जीवाश्मीकरण (Fossilisation) प्रक्रिया द्वारा कोयला, पेट्रोलियम और प्राकृतिक गैस में बदल गए।
कोयला मुख्यतः प्राचीन वनों से बना, जबकि पेट्रोलियम समुद्री सूक्ष्म जीवों से बना।
⭐ Extra Facts / अतिरिक्त तथ्य
🔹 Coal is called “buried sunshine” because it stores energy from ancient plants.
🔹 Fossil fuels are non-renewable resources — they take millions of years to form.
🔹 Petroleum is often called “black gold” due to its high economic value.
🔹 भारत में प्रमुख कोयला क्षेत्र झारखंड, ओडिशा और छत्तीसगढ़ में पाए जाते हैं।
🔹 Burning fossil fuels releases carbon dioxide, contributing to global warming.
