Across
- 5. the form of water falling from the sky, such as rain, snow or hail
- 6. radioactive metal used as a fuel in nuclear reactors
- 10. a body of permeable rock below the Earth’s surface which contains water, known as groundwater
- 11. the area of land next to the river, usually reaching to the base of the mountains surrounding the catchment. It experiences flooding during peak rainfall periods.
- 14. lines on a map that join places with the same air pressure
- 15. the layer of the atmosphere closest to the Earth. It extends about 17 kilometres above the Earth’s surface, but is thicker at the tropics and thinner at the poles, and is where weather occurs.
Down
- 1. a scientist who studies the weather
- 2. to change liquid, such as water, into a vapour (gas) through heat
- 3. vapour water in its gaseous form, formed as a result of evaporation
- 4. precipitation not absorbed by soil, and which runs over the land and into streams
- 7. a landform at the mouth of the river where a river splits into smaller streams and sediment is deposited to create an arch of land reaching out into the sea.
- 8. an instrument used to measure air pressure
- 9. a curve in a river caused by fast-flowing water eroding the bank of one side of the river and slow-flowing water depositing sediment on the other side of the river
- 12. also known as an embankment, it is a built-up part of the river bank
- 13. recharge a process in which water moves down from the Earth’s surface into the groundwater
