Chapter 8: Earth’s Climate System and Natural Changes 8.1 Weather and Climate Weather: atmospheric conditions in a particular location over a short period of time Information to provide when describing the weather: · Temperature · Type and amount of precipitation · Wind speed · Relative humidity (the amount of water vapour in the air relative to the maximum amount of water that it is possible for the air to hold at that temperature) Atmospheric pressure (the fore exerted on a surface by the weight of the air above it) o Presence of fog, mist or cloud cover Weather is caused by interactions between water and air on Earth and energy from the Sun. Air movement and water movement create weather. Climate: the average of the weather in a region over a long period of time. Information to provide when describing the climate: · Range of temperatures you might expect at a certain time of year · Whether to expect rain, snow, or high winds in certain seasons The climate of a region determines the types of plants and animals that live there. 8.2 Classifying Climate Climate zones: regions of similar temperature, precipitation and plant communities. Ecoregions: climate zones which focus on the ecology of the region. Bioclimate Profiles: a graphical representation of current and future climate data from a specific location. Factors affecting climate: · The distance from the equator (latitude) · The presence of large bodies of water · The presence of ocean or air currents · Land formations · The height above sea level (altitude) 8.3 The Sun Powers Earth’s Climate System Climate System: the complex set of components that interact with each other to produce Earth’s climate. Ultraviolet radiation: a form of invisible higher-energy radiation Infrared radiation: a form of invisible
