The Big Questions (page 27)

1. Oceans aur continents kya hain? Unke naam aur failaav kya hai?

Oceans Prithvi ke sabse bade jal-bhandaar hain, aur continents zameen ke bade lagaataar hisse. Paani satah ka lagbhag teen-chauthaai aur zameen ek-chauthaai se thoda zyaada hissa dhakti hai. Paanch oceans hain, Pacific, Atlantic, Indian, Southern aur Arctic, sab jude hue. Continents aksar saat gine jaate hain: Asia, Africa, North America, South America, Antarctica, Europe aur Australia. Ye barabar nahi faile: Northern Hemisphere mein zyaada zameen hai, aur Southern mein kahin zyaada paani.

2. Oceans aur continents Prithvi par jeevan, insaani jeevan samet, ko kaise prabhaavit karte hain?

Ye mausam banaate hain. Oceans continents par baarish bhejte hain, jaise India ka monsoon; inke paudhe duniya ki aadhi se zyaada oxygen banaate hain; aur ye anginat samudri paudhon aur jaanwaron ka ghar hain. Logon ne samudron se pravaas, vyapaar, yuddh aur machhli pakadne ka kaam kiya hai, aur tateey sanskritiyon mein samudr ki kai kahaaniyan hain. Oceans cyclone aur tsunami jaise khatre bhi laate hain. Badle mein insaani gatividhiyan plastic, doosre pradooshan aur zaroorat se zyaada machhli pakadkar oceans ko nuksaan pahunchaati hain.

In-text sawaal (pages 28 aur 33)

Globe par sabse zyaada faila rang neela hai, jo paani dikhaata hai; Prithvi zyaadatar paani se dhaki hai. Prithvi ki photo mein safed aakaar baadalon ke bade samooh hain, jo continents par baarish laate hain.

Let’s Explore: polar maps (page 29)

• Har pole ke chaaron or gol lines parallels of latitude hain, aur poles se nikalti lines meridians of longitude hain, poles ke upar se dekhi hui.
• Southern Hemisphere mein zyaada paani hai.
• Anupaat: Northern Hemisphere mein mote taur par 3 hisse paani aur 2 hisse zameen, aur Southern mein mote taur par 4 hisse paani aur 1 hissa zameen hai. (Extra: lagbhag 61 pratishat aur 81 pratishat paani.)
• Kya oceans jude hain? Haan. Ye ek juda hua jal-bhandaar hain; inke beech ke bantwaare sirf maanyata se kheenchi lines hain.

Think About It: paani ki kami (page 31)

Itna paani hone par bhi paani ki kami ki baat kyun? Lagbhag saara paani khaara samudri paani hai jise hum na pee sakte hain na kheti mein laga sakte hain. Meetha paani bahut thoda hai, aur uska bada hissa glaciers mein jama ya zameen ke bahut neeche hai. Nadiyon, jheelon aur groundwater mein jo bachta hai wo asamaan roop se faila hai, aksar pradooshit hai, aur badhte shehron, kheton aur udyogon dwaara tezi se khatam ho raha hai.

Paani bachaane ke tareeke: brush karte waqt nal band karna, tapakte nal aur pipe theek karna, shower ya pipe ki jagah baalti use karna, paani dobaara use karna (jaise sabzi dhone ka paani paudhon ke liye), baarish ka paani ikattha karna (rainwater harvesting), aur kheton mein drip irrigation. Jawab is pe nirbhar honge ki tumne ghar, school aur apne gaon, kasbe ya shehar mein kya dekha hai.

Let’s Explore: continents ka diagram (page 36)

• Sabse bada: Asia. Sabse chhota: Australia.
• North America ya South America? North America bada hai. Africa ya North America? Africa. Antarctica ya Australia? Antarctica.
• Eurasia: Europe aur Asia ko ek rang dene se Eurasia banta hai, jo South America se teen guna se bhi zyaada bada hai.
• Sabse chhote se sabse bade tak: Australia, Europe, Antarctica, South America, North America, Africa, Asia.

Questions, activities and projects (pages 39–40)

1. In shabdon ko samjhao

• (a) Continent: Prithvi par zameen ka bada, lagaataar hissa, jaise Asia ya Africa. Aksar saat continents gine jaate hain.
• (b) Ocean: Prithvi ke sabse bade jal-bhandaaron mein se ek, jisme khaara paani hai. Paanch hain, sab jude hue: Pacific, Atlantic, Indian, Southern aur Arctic.
• (c) Island: continent se chhota zameen ka tukda, jo chaaron taraf paani se ghira ho, jaise Greenland ya Andaman Islands.

2. Continents haath se banao

Map dekhe bina saat kachche aakaar mote taur par sahi jagah banao: baayein taraf dono America (upar North, neeche South), beech mein Europe aur Africa, upar-daayein Asia, neeche-daayein Australia aur neeche Antarctica. Har ek mein rang bharo, phir book ke map se milaao. Dekho tumhaare aakaar ya size kahan alag hain, jaise kya tumne Asia kaafi bada banaaya ya Africa kaafi neeche tak.

3. Outline map par continents aur oceans ke naam likho

Saat continents aur paanch oceans ke naam in jagahon par likho:

• Pacific Ocean: sabse bada, dono America ke paschim aur Asia aur Australia ke poorv (world map ke dono kinaaron par dikhta hai).
• Atlantic Ocean: ek taraf dono America aur doosri taraf Europe aur Africa ke beech.
• Indian Ocean: Asia ke dakshin mein, Africa aur Australia ke beech.
• Arctic Ocean: North Pole ke chaaron or, sabse upar.
• Southern Ocean: Antarctica ke chaaron or, sabse neeche.

4. Crossword

Across

Clue	Answer
1. Oceans bahut banaate hain	OXYGEN
3. Zameen ka bada failaav	CONTINENT
6. Bada continent jiska India hissa hai	EURASIA
8. Oceans ke pradooshan ka bada srot	PLASTIC
10. Sabse thanda continent	ANTARCTICA

Down

Clue	Answer
2. Prithvi ka sabse bada island	GREENLAND
4. Ocean ki vishaal vinaashkaari leher	TSUNAMI
5. Sabse chhota continent	AUSTRALIA
7. Prithvi ka sabse bada jal-bhandaar	PACIFIC
9. Samudr se ghira bhoo-bhaag (continent nahi)	ISLAND

6 Across mein saat khaane hain, isliye jawab ASIA nahi, EURASIA hai; iske akshar GREENLAND, TSUNAMI aur AUSTRALIA se milte hain.

Aur practice ke liye padho: duniya ke oceans aur duniya ke continents.
