Answer this question for me?

1.) cool air takes up ___space is the answer.

As air gets warm, the air molecules have more energy and move around more, taking up more space. As the warm air expands, it becomes less dense than the cold air, so rises up and floats above the cold air.

2.) Without the wind there would be no weather.

Wind is moving air and is caused by differences in air pressure within our atmosphere. Air under high pressure moves toward areas of low pressure.

3.) Wind is moving air and makes weather

I think don't quote me on that one lol.

a and b because with the other three, they simplify to something else.
