Question

what happens when the humidity is low or high? give examples of each

Answer 1

Think of the air as a glass and you want to know how much water it can hold. If you add more water to the glass, then the relative humidity will go up. The air acts in the same way.

When the humidity is high, there is enough water in the air to make rain or snow. Humidity can change a lot during the day. Why? A change in temperature causes a change in pressure. If the humidity was 100% and the temperature goes down, the air pushes together and squeezes out water. This is our rain and snow!

Humidity is important for clouds too because they are made of water and ice. If the humidity is high, there is a lot of water that can be used to make clouds. The larger the amount of water, the more clouds we can have.

Answer 2

When relative humidity reaches a high enough level, the body natural cooling system simly cannot work Sweat evaporate very slowly if all the body heats up.
Low humidity causes static electricity, dry skin, lips and hair, scratchy throats and noses are itching and chapping .
