Climate – A pattern of weather over a time period Climate zones – Geographers divide the Earth into climate zones to help the study of the Earth. Each zone has a pattern of temperature and precipitation
The patterns of weather are shown on a climagraph The Climagraph shows the average temperature and precipitation in a place over a year. Look at the labels on the sides and along the bottom.
5 main Climate Zones –look in your books pages 30-31 Tropical Dry Temperate Cold Polar
Location affects climate Things that affect Temperature Latitude is the most important – affects direct sunlight Elevation (Altitude) affects temperature – Places at higher elevations are cooler
Vegetation – Plants and tress that grow in an area – see pages 32-33 Climate has an effect on vegetation Colder Climate zones bushes and small plants grow Hot climates cacti grow Trees Coniferous trees – Needles and cones Deciduous Trees – Broad flat leaves that shed before winter
