Class 6 Science Chapter 11: Nature's Treasures (Hinglish Notes)
Ye chapter 5 lines mein
Prakriti ke khazaane natural resources hain: hawa, paani, Sun ki energy, jungle, mitti, chattanein, minerals aur fossil fuels. Saare living beings inpe nirbhar hain. Inse insaan jo cheezein banata hai, jaise bulb, furniture aur cycle, wo human-made resources hain. Jo resources prakriti ek theek samay mein dobara bhar deti hai, jaise hawa, paani aur jungle, wo renewable hain; jo seemit hain aur samay pe dobara nahi bante, jaise minerals, mitti, chattanein, coal, petroleum aur natural gas, wo non-renewable hain. Isliye inhe samajhdaari se use karna chahiye.
Prakriti ke khazaane
Bhoomi aur Surya school ki chhuttiyon mein Western Ghats mein jungle ke kinaare ek gaon mein apni Ajji (yaani daadi ya naani) ke paas jaate hain. Wahan hawa taazi hai, mitti upjaau hai, khoob dhoop hai, aur chaaron taraf pahaad, jharne, paudhe, jaanwar aur pakshi hain. Ajji inhe prakriti ke khazaane kehti hain. Hamein inki zaroorat jeene ke liye aur zindagi aasaan banaane ke liye hai; inke bina Earth pe koi jeevan sambhav nahi. Hum bhi prakriti ka hissa hain.
Hawa
Saans rok ke dekho: jaldi hi phir saans leni padti hai, kyunki shareer ko kaam karne ke liye hawa ki oxygen chahiye. Hum khaane ya paani ke bina kuch din jee sakte hain, par oxygen ke bina kuch minute bhi nahi.
Hawa gases ka mishran hai: lagbhag 78% nitrogen, 21% oxygen aur 1% argon, carbon dioxide aur doosri gases. Chalti hui hawa wind kehlaati hai. Ye kaagaz ki firki ghumaati hai, aur windmills ke pankh bhi, jo aata chakki chalaate hain, kuon se paani kheenchte hain ya bijli banaate hain. India mein kai windmill farms hain, jaise Tamil Nadu ka Muppandal, Rajasthan ka Jaisalmer Wind Park aur Maharashtra ka Brahmanvel.
Paani
Hamein peene, khaana pakaane, nahaane, dhone, safaai, kheti aur udyogon ke liye paani chahiye. Paani Earth ki satah ke lagbhag do-tihaai hisse ko dhakta hai, par zyaadatar samundar mein hai aur khaara hai. Meetha paani baraf, nadiyon, jheelon aur zameen ke neeche milta hai, aur iska sirf thoda hissa, talaab, nadi, jheel aur kuon mein, aasaani se milta hai. India ki kai jagahon pe paani ki kami hai. Isliye paani barbaad na karo, saaf rakho aur bachao, jaise rainwater harvesting se. Rajasthan ki bawadi aur Gujarat ki vav jaise stepwells sadiyon se paani ikattha karti aayi hain. World Water Day 22 March ko manaaya jaata hai.
Sun ki energy
Sun Earth pe energy ka mukhya srot hai. Paudhe dhoop se khaana banaate hain, jaanwar paudhe khaate hain, aur hum dono se khaana paate hain, isliye hamare khaane ki saari energy pehle Sun se aayi. Hum uski garmi aur roshni se kapde, mirch aur anaaj sukhaate hain, aur uski energy seedhe solar panels (bijli), solar cooker aur solar water heater mein use karte hain.
Jungle
Jungle aise bade ilaake hain jahan paudhe ghane ugte hain. Ye jangli jaanwaron, pakshiyon aur keedon ko khaana aur ghar dete hain, aur hamein lakdi, phal, jadi-bootiyan aur bahut kuch. Bade paimaane pe ped katne se jungle ghatte ja rahe hain, aur jungle ko dobara ugne mein bahut saal lagte hain. India mein jungle bachaane ki purani parampara hai: pavitra upvan (sacred groves), July mein manaaya jaane waala jungle ka tyohaar Van Mahotsav, aur Chipko movement, jo 1970s ki shuruaat mein aaj ke Uttarakhand mein shuru hua, jab local mahilaon ne pedon ko gale lagaakar bachaaya.
Mitti, chattanein aur minerals
Jadein mitti ko pakad ke bahne se rokti hain, aur giri hui pattiyan sad ke use poshan deti hain: prakriti mein recycling. Mitti tab banti hai jab Sun, paani aur jeevon ke asar se chattanein hazaaron saalon mein tootti hain. Granite, sandstone, marble, slate aur laterite jaisi chattanein imaaraton, sadkon aur auzaaron mein kaam aati hain. Chattanein minerals se bani hain, jinse aluminium, sona, taamba aur loha jaise dhaatu nikaale jaate hain; ek saadhaaran mobile phone mein lagbhag ek darjan minerals hote hain.
Fossil fuels
Petrol, diesel aur kerosene petroleum se milte hain. Petroleum, natural gas aur coal fossil fuels hain, jo zameen mein dabe sookshm jeevon aur paudhon ke avsheshon se laakhon saalon mein bane. Natural gas khaana pakaane, bijli banaane aur CNG ke roop mein gaadiyon ke saaf indhan ke liye use hoti hai; coal zyaadatar bijli banaane mein lagta hai. Fossil fuels seemit hain, aur inhe jalaane se dhuaan aur carbon dioxide nikalti hai jo hawa ko pradooshit karti hai. Paidal chalna, cycle aur public transport inhe bachaate hain.
Renewable aur non-renewable resources
Prakriti se mile resources natural resources hain; unse insaanon ki banaayi cheezein, jaise bulb, furniture, solar panels aur cycle, human-made resources hain. Renewable resources, jaise hawa, paani aur jungle, prakriti theek samay mein dobara bhar deti hai. Non-renewable resources, jaise minerals, mitti, chattanein, coal, petroleum aur natural gas, seemit hain aur khatam ho jaate hain. Aur padho natural resources kya hain, renewable aur non-renewable aur natural resources kaise bachayein mein. Poore chapter ke jawab Chapter 11 ke NCERT solutions mein hain.
Key terms (zaroori shabd)
