The question it poses is just one of a series of eight questions which are examined in detail in an on-line resource called 'Earth Guide' produced by the Japan Science and Technology Agency. (Click the image above to link). From the home page, you progress to a 'question map' containing eight questions. (Incidentally, there is a octave of sound attached to the questions as you roll the mouse over them and if you are very clever and have nothing better to do, I have discovered that you can even make a tune! !)The question shown above (4) and the one relating to the water cycle (5) are very relevant to the Atmosphere and Hydrosphere units respectively. You might like to explore them while you are revising.
Don't forget that we are expecting you here in the department tomorrow afternoon. We will start the 'swot shop' at 2. The plan is to divide you into two groups and to devote an hour to Physical and an hour to Human, swapping groups round halfway through the afternoon.
