Essay Questions: Marking Guide for Teachers and Parents
- (a) The continuous movement of water between the Earth’s surface and the air (2). (b) The same changes repeat again and again and never end (2). (c) The Sun (1).
- Evaporation: Sun heats water and it turns to vapour (2). Transpiration: plants lose water vapour through leaves (2). Condensation: vapour cools and forms clouds (2). Precipitation: water falls as rain (2). Collection or runoff: water flows into rivers, lakes, the sea or soaks into the ground (2).
- A neat labelled diagram: sea or river and Sun, arrows for evaporation going up, clouds for condensation, rain for precipitation and arrows showing water flowing back into rivers and the sea (1 mark for each stage correctly drawn and labelled, 1 mark for neatness).
- Any four: gives fresh water for drinking, rain for crops, fills rivers and dams for electricity, supports plants and animals, controls climate, cleans water through evaporation (1 mark each).
- Any four: cutting down forests, galamsey, polluting rivers with refuse, burning bushes, climate change (1 mark each). Protection: planting trees, keeping rivers clean, saving water (2 marks).
