Hot air balloons can fly from land to ocean during the day.
A hot air balloon is a balloon that uses hot air as a floating gas. There is a large opening and a hanging basket at the bottom of the airbag to heat the cold air. It can fly as long as there is air, so it can fly during the day.
Hot air balloons use heated air or certain gases such as hydrogen or helium that are less dense than the air outside the balloon to create buoyancy.
Although flying animals such as birds can fly through the air, they must use land or water as their habitat. For example, they want to drink water and lay eggs on land; some flying insects live as adults. On land, the larvae live in water.
