Across
- 1. the process of turning from liquid into vapor.
- 5. a biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth.
- 7. a cavity in the ground, especially in limestone bedrock, caused by water erosion and providing a route for surface water to disappear underground.
- 8. a severe snowstorm with high winds and low visibility.
- 10. bodies of ice that are found in the mountains.
- 12. the transition of a substance directly from the solid to the gas state, without passing through the liquid state.
- 13. a shaft sunk into the ground to obtain water, oil, or gas.
- 15. permeation of a liquid into something by filtration.
- 17. a large natural stream of water flowing in a channel to the sea, a lake, or another such stream.
- 19. water which collects as droplets on a cold surface when humid air is in contact with it.
- 23. transformation of gas into solid without an intermediate liquid phase
- 26. the amount of salt in a liquid.
- 28. a quantity representing the amount of water vapor in the atmosphere or in a gas.
- 29. a very large expanse of sea, in particular each of the main areas into which the sea is divided geographically.
- 30. a glacial episode during a past geological period.
- 32. one that is below the freezing temperature throughout its mass for the entire year; a subpolar (or polythermal) glacier contains ice below the freezing temperature.
- 33. a high-latitude region of a planet, dwarf planet, or natural satellite that is covered in ice.
- 36. found in Lakes and rivers; not of the sea.
Down
- 2. a geological interval of warmer global average temperature lasting thousands of years that separates consecutive glacial periods within an ice age.
- 3. a spring of naturally hot water, typically heated by subterranean volcanic activity.
- 4. a hot spring in which water intermittently boils, sending a tall column of water and steam into the air.
- 6. an all-encompassing term for those portions of Earth's surface where water is in solid form, including sea ice, lake ice, river ice, snow cover, glaciers, ice caps, ice sheets, and frozen ground.
- 9. a high-latitude region of a planet, dwarf planet, or natural satellite that is covered in ice.
- 11. a rising of seawater, magma, or other liquid.
- 14. purifying water for human use.
- 16. an overflowing of a large amount of water beyond its normal confines, especially over what is normally dry land.
- 18. the draining away of water (or substances carried in it) from the surface of an area of land, a building or structure, etc.
- 20. a large body of water surrounded by land.
- 21. the weather conditions prevailing in an area in general or over a long period.
- 22. the action or process of precipitating a substance from a solution. Rain, snow, sleet, or hail that falls to the ground.
- 24. the envelope of gases surrounding the earth or another planet.
- 25. a body of permeable rock which can contain or transmit groundwater.
- 27. the branch of science concerned with the properties of the earth's water, and especially its movement in relation to land.
- 29. a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences.
- 31. a prolonged period of abnormally low rainfall, leading to a shortage of water.
- 34. a cave, or a chamber in a cave, typically a large one.
- 35. the tidal mouth of a large river, where the tide meets the stream.
