Wind and lift

What causes the wind?

We saw in our experiment that heat cause air, or water, to move. This is the same force that make the wind. The sun heats up the earth, and that causes the air to heat up. That hot air then moves upwards, and other cold air has to move in to place. This movement of the air is the wind

                            The picture above shows how it works with the sun causing the warm air



Effects of the wind

If we had no wind the weather wouldn't change it would always rain and be sunny outside so that's why we have wind so the weather can change.


how wind helps us   

if we go sailing it can help us go the way we want and it will make us more so we do not stay in one place and we can go to were we want to go. And it can help us with so much more in stuff that we need to do.
