Presentation Transcript

  1. Ø describe and interpret climate maps, diagrams and graphs Ø construct and analyse climate graphs Ø describe and explain climate graphs comment on the accuracy of statements which describe climate patterns Ø shown on maps etc. GMTs

  2. THE ATMOSPHERE ATMOSPHERE VIDEO

  3. HIGHER GEOGRAPHY PHYSICAL ENVIRONMENT ATMOSPHERE

  4. Ø explain with the aid of an annotated diagram, why Tropical latitudes receive more of the sun’s energy than Polar regions Ø explain why there is a net gain of solar region in the Tropical latitudes and a net loss towards the poles Ø describe the role of atmospheric circulation in the redistribution of energy over the globe Ø describe and explain the earth’s energy exchanges shown on a diagram Ø describe the factors which affect the amount of sunlight reflected from the earth’s surface Ø describe and account for the generalised pattern of atmospheric circulation and global or winds, ocean currents shown on a world map Ø describe the variations in world temperature for the last 100 years (shown eg. on a graph) and suggest both physical and human reasons for these variations Ø describe and explain the origin, nature and weather characteristics of Tropical Maritime ( mT) and Tropical Continental ( cT) air masses which affect West Africa Ø with reference to the Inter-Tropical Convergence Zone and the movement of air masses, describe and account for the variations in West African rainfall. By the end of this topic you should be able to:

  5. ATMOSPHERIC GASES Nitrogen - 78% Oxygen - 21% Carbon dioxide - 0.036% …...and rising!! Water vapour - variable - up to 4% over tropical oceans. (as humidity increases the relative amounts of other gases decrease).

  6. Troposphere = main zone of weather and climate. lapse rate = decrease in temperature with altitude = 6.4ºC for every 1000metres

  7. ACTIVITIES PUT THE HEADING: ‘THE STRUCTURE OF EARTH’S ATMOSPHERE’ READ PAGE 4 AND 5 IN THE TEXTBOOK • COMPLETE QUESTION 1 AND 2 ON PAGE 32 • MAKE A COPY OF FIGURE 2.1 ON PAGE 5 http://www.bbc.co.uk/scotland/learning/learningzone/clips/4316/

  8. Mt Everest (8800metres) Calculate the difference in temperature between sea level and the summit of the mountain.
