Air currents move objects in the air. Explain how a convection current might affect the flight of a hot air balloon

Chemistry

Hot/ warm air is less dense than cold/cool air. Therefore warm/ hot air rises and cool/cold air falls in the atmosphere to create convection currents. The hot air balloon also uses this concept to fly. The air in the balloon is heated by the inbuilt flamer and when the air rises in temperatures (in comparison to ambient air temperatures) it becomes less dense and begins to rise. This raises the balloon into the atmosphere.

Is there a solution for the impacts overfishing?
Lera25 [3.4K]

Answer:

The world’s oceans are so big we thought for a long time that there was nothing humans could do to hurt them. Now we’re facing an imminent and global collapse of our fisheries, projected to happen as early as 2048, thanks to overfishing, wasteful fishing practices and massive overconsumption. But, there are a few key tried-and-tested solutions to overfishing that have been successfully implemented around the world. The trick is to scale these solutions up to a global scale, encouraging countries that have originally been resistant to helping and get them onboard, and supporting countries that don’t have the means to update their fishing policies themselves.

Hope it will help you
