Air-current cycles drive the Earth's water supply through a cycle of its own, called the hydrologic cycle. As the sun heats liquid water, the water evaporates into vapor in the air. The sun heats the air, causing the air to rise in the atmosphere. ... How Electricity Works...

The Hydrological Cycle; (also known as the water cycle) is the journey water takes as it circulates from the land to the sky and back again. The sun's heat provides energy to evaporate water from the earth's surface (oceans, lakes, ... A network of underground pipes, pumping stations and treatment works ensures that clean,

Water is essential to everyday life. If we didn't have water the biosphere wouldn't be possible. 93% of our water is in oceans and that is important. The hydrologic cycle is basically one of condensation, precipitation, and evaporation. The...

If you observed or performed Activity 7 from the last chapter, you saw how heat changed water from liquid to steam, and from solid to liquid. In the same way, water molecules in the atmosphere need the sun's power or energy to keep moving a...

Water's natural change of forms is called the Hydrologic Cycle. This cycle includes evaporation (water going into the air); condensation (forming clouds); precipitation (rain, snow, sleet, and hail); runoff (as rainwater flows into surface sources);

The hydrologic cycle begins with the evaporation of water from the surface of the ocean. As moist air is lifted, it cools and water vapor condenses to form clouds. Moisture is transported around the globe until it returns to the surface as precipitation.

Water moves continuously through a natural system called the hydrologic cycle. Powered by the heat of the sun, all the water that falls to the ground as precipitation sooner or later makes its way back into the clouds where it eventually becomes precipitation again.
