Answer:
If you mean by air pressure, High air pressure is how much air there is upon you. IF you were on the death valley, you would have lots of air pressure. If you were on a mountain, there would be little air pressure. If there is high pressure, there is good weather
If you mean the other pressure, then it is this. If there is a lot of pressure, then you are intimidated, and there is lots of people looking at you. Visa Versa for low pressure.
