उपलब्ध है।
Rotation of the Earth
English
The Earth spins on its own axis.
This movement is called rotation.
- One rotation takes 24 hours (1 day).

Day and Night
English
Day and night occur because the Earth rotates.
- The side facing the Sun has day.
- The side away from the Sun has night.
हिन्दी
दिन और रात पृथ्वी के घूर्णन के कारण होते हैं।
- सूर्य की ओर वाला भाग — दिन
- सूर्य से दूर वाला भाग — रात
Seasons
The Earth experiences four main seasons:
- Summer
- Rainy (Monsoon)
- Autumn (where applicable)
- Winter
The change of seasons is due to the Earth's revolution around the Sun and the tilt of its axis.
हिन्दी
मुख्य ऋतुएँ—
- ग्रीष्म
- वर्षा
- शरद (जहाँ लागू)
- शीत
ऋतुओं का परिवर्तन पृथ्वी के परिक्रमण और उसकी धुरी के झुकाव के कारण होता है।
