Prithvi Ki Utpatti Aur Vikas

Prithvi ki utpatti kareeb 4.6 billion saal pehle hui. Yah Big Bang theory aur nebular hypothesis par aadharit hai. Shuruaat mein prithvi ek garma-garam gola tha, jo dheere-dheere thanda hua aur iski paratan (layers) bani.

Prithvi Ke Aandrik Bhag

• Bhupatal (Crust): Sabse upar ki parat, jiska motai 5-70 km tak hai.
• Bhupatal ke neeche (Mantle): 2900 km motai, yahan silicates aur magnesium paid hai.
• Core: Andar ka gola, jismein nickel aur loha hai. Bahari core drav hai, andari core thos.

Jalvayu Aur Mausam

Jalvayu ka matlab hai kisi sthaan ka lambe samay ka mausam pattern. Mausam (weather) har roz badalta hai, jabki jalvayu (climate) salo-salo mein badalta hai. Jalvayu ko prabhavit karne wale karan: latitude, altitude, samundra se doori, aur vayu dharayein (wind currents).

Jalvayu Ke Pramukh Prakar

• Ushan Kshetra (Tropical): Garam aur barish wala.
• Temperate: Samrit jos.
• Thandi (Polar): Baraf aur thand.

Samundra Aur Mahasagar

Prithvi par 71% bhaag paani se dhaka hai. Samundra ki gahrai aur jal dharayein (currents) jalvayu ko prabhavit karti hain. Major oceans: Pacific, Atlantic, Indian, Arctic.

Samundra Ke Hisse

• Continental Shelf: Kinaray ka chhala, gambhir 200 m tak.
• Continental Slope: Dhawan, jaha gambhir 2000-4000 m ho jati hai.
• Abyssal Plain: Samundra ka flat hissa, gambhir 4000-6000 m.

Bhoogolik Prakriyayein (Geomorphic Processes)

Zameen ki satah par badlav laane wale karan: weathering, erosion, deposition. Weathering chattanon ko todti hai, erosion unhe udati hai, aur deposition naye sthaan par bithata hai. Inke karan hi parvat, nadiyaan, aur ghaatiyaan banti hain.

Erosion Ke Mukhya Karan

• Nadiyaan (Fluvial): Paani ke bahao se ghaatiyaan aur delta.
• Hawa (Aeolian): Registan mein rukhsar aur sand dunes.
• Glaciers: Baraf ke bahao se U-shaped valleys.
