Answer:
Table 13.1 Interesting features about the Earth
| S.No | Interesting features of the Earth |
| 1. | The air we breathe doesn't fly off and disappear into space. (We learnt in Chapter 7 that the particles of a gas move freely, and gases do not have a fixed volume) |
| 2. | We can stand on the ground held by gravity (as we learnt in Chapter 5), but our heart can pump blood up to our head. |
| 3. | Water stays on Earth's surface and doesn't float away - thanks to gravity. This allows rivers, lakes, and oceans to exist and support life. |
| 4. | Earth's temperature is just right - not too hot or cold - so water remains liquid and life can survive. This is because of its perfect distance from the Sun and protective atmosphere. |
