What makes objects to Float In The Air 

• Air pressure makes objects like aircraft to stay and float in the air during flight
• Hot air is lighter that cold air . That makes balloons filled with hot air to float .
• Some objects are very dried  , thin and light weight and that makes it very easy for them to float in the air .
• Birds and aircrafts have wings that help them to fly in the sky

 

Importance or Benefits of objects Floating in the air 

• Air transportation from one place to another is possible because some objects can float in the air
• Transfer of pollen grain or pollination is possible
• some sports are done by making use of air glider
