this helps you learn more about the development of fronts and masses with the aid of the diagrams I still have to finfish it tho

key terms on the restless atmosphere
The maximum and minimum thermometer is a glass tube that is used to measure the temperature
*the glass tube contains alcohol and mercury
*as the temperature rises, mercury moves up the maximum tube. A piece of metal in the tube marks the highest point reached.
*as the temperature drops mercury moves up the minimum tube a piece of metal in the tube marks the lowest point reached.
Air Masses is a large body of air that has the same temperature, atmospheric pressure and humidity throughout. Air masses move around and bring certain weather conditions with them.
Fonts= as the properties of air masses are different they do not mix well. when two air masses meet an imaginary line of boundary develops between them. This is called a front. fronts can be cold or warm.
A cold front develops where a cold air mass advances on a cold air mass.
1. the cold air mass pushes against the warm air mass, which is lighter.
2.The warm air mass is forced to rise quickly .
3.the warm air cools as it rises. causing condensation to take place.
4.This results in heavy cloud and rain.
