Key Ideas Geographers study the weather because weather conditions have an impact on people’s daily lives and their activities. Weather is the day to day changes in the atmosphere. Climate is the overall average pattern of weather Precipitation is water from the atmosphere. It can be in solid or liquid form. It rains because when warm air rise, with water vapour, it expands, condenses, & cools. The cooling forms clouds & mini water droplets that eventually become to heavy &fall back to the earth. There are three main types of rainfall – relief, convectional and frontal. In all three situations, rainfall occurs because air is forced to rise. 31 of 40 © Boardworks Ltd 2006
