How is Space Different from Earth?
Earth is the perfect place for life, but space is completely different and extremely hostile. Let’s compare
| Feature | Earth | Space |
| Gravity | Strong, holds everything in place | Weak or absent, causing weightlessness |
| Atmosphere | Oxygen-rich, protects from radiation | No air, unprotected from cosmic rays |
| Temperature | Ranges from -89°C to 56°C | Extreme heat and cold |
| Sound | Air allows sound waves to travel | No air, so sound cannot exist |
| Pressure | Keeps our bodies stable | Vacuum, causing fluids to boil instantly |
🔍 Key Takeaways:
✅ Gravity keeps us grounded, but in space, astronauts float.
✅ Space has no air, so sound cannot travel.
✅ Temperatures range from boiling to freezing within minutes!
