2 Water Cycle - in pairs Use the pens and pencils to draw your version of the water cycle. Make sure you include the following terms: 1. Water vapour in atmosphere (13,000 km 3 ) 2. Precipitation over land (110,000 km 3 ) 3. Precipitation over ocean (390,000 km 3 ) 4. Evaporation from ocean (430,000 km 3 ) 5. Evaporation from land (70,000 km 3 ) 6. Snow and ice (29 million km 3 ) 7. Lakes and rivers (200,000 km 3 ) 8. Run-off from land (40,000 km 3 ) 9. Groundwater (8 million km 3 ) 10. Ocean (1,348 million km 3 )
