What are high and low pressure weather systems? What causes them and what makes them move?

The Earth be is not heated evenly. At the bare basics you have the night side, and then the poles compared to the equator.

This causes zones of hot air that tends to be lighter, and cold sir that tends to be heavier.

Heavy air presses down on the material beneath it more, creating a high pressure done. By this pushes surrounding air away. You can feel this every time you open a refrigerator as the cold sir spills down to chill your feet.

Low pressure zones are where the air is getting pushed towards. As air is headed this way all the water in the air is drawn there too. One it arrives it collide with air coming from the other direction. This causes some of it to move up, cool and condense into clouds.

Larger differences in air pressure (usually referred to as lower pressure) mean this happens faster, with more energy. Regaining in higher winds, more clouds and worse weather.
