Practice sheet systmes & models 1

  1. 1. Guru charan kumar IB ESS 2013 SYSTEMS & MODELS WORKSHEET The figure below shows a model of the climatic system. Radiation outputs from Earth-atmosphere Atmosphere Solar inputs to Earth-atmosphere Ocean Oceanic circulation Atmospheric circulation and composition Ice CLIMATE Land and terrestrial features Human activity Earth-atmosphere system External inputs and outputs of the climatic system Internal interactions of the climatic system [Source: O’Hare and Sweeney, The Atmospheric System, (1986), Oliver and Boyd, page 189] (a) Define the term model. ...................................................................................................................................... ...................................................................................................................................... ...................................................................................................................................... (2) (b) Identify two internal interactions in the figure above which affect the climate. ...................................................................................................................................... ...................................................................................................................................... (1) (c) List four gases which are part of the atmosphere.
