ACTIVITY 3: Knowledge Check!Directions: List at least 5 importance of gravity in our daily lives1______2______3______4______5______​

Answer:

Gravity is very important to us. We could not live on Earth without it. The sun's gravity keeps Earth in orbit around it, keeping us at a comfortable distance to enjoy the sun's light and warmth. It holds down our atmosphere and the air we need to breathe.

1. Gravity is very important to our everyday lives. Without Earth’s gravity we would fly right off it. It is the Sun’s gravity that keeps Earth in orbit around the Sun. Life on Earth needs the Sun’s light and warmth to survive.2. Gravity keeps everything on Earth from floating away.3. Gravity is the force that pulls objects to Earth.4. Without gravity, we would have no atmosphere. This means that there would be no air to breathe.5. Lastly, gravity helps the Earth to stay just the right distance from the Sun, so it’s not too hot or too cold.
