Water in the World: The Water Cycle

Water doesn't stay in the same place. Rivers flow. Clouds blow. Ice melts. Ocean currents move. Environmental factors affect the movement of water and this is described as the water cycle. Read through this website to learn more.

The natural water cycle shows the constant movement of water around the world. Water moves through the processes of evaporation, transpiration, condensation, precipitation, run-off, infiltration and percolation. Read through this website to learn more.

The water cycle describes how water is exchanged (cycled) through Earth's land, ocean, and atmosphere. Read through this article to learn more.

All of the earth's water already exists, captured in the ground, oceans, lakes, ice, snow and the atmosphere. Through the natural water cycle, water is used over and over again. Read through this website to learn more.

The water cycle is a way that water moves all around the Earth. It never stops and doesn't really have a beginning or an end. It's like a big circle. Read through this website to learn more.

Viewed from space, one of the most striking features of our home planet is the water, in both liquid and frozen forms, that covers approximately 75% of the Earth’s surface. Geologic evidence suggests that large amounts of water have likely flowed on Earth for the past 3.8 billion years—most of its existence. Believed to have initially arrived on the surface through the emissions of ancient volcanoes, water is a vital substance that sets the Earth apart from the rest of the planets in our solar system. In particular, water appears to be a necessary ingredient for the development and nourishment of life. Read through this website to learn more.

The water cycle describes how Earth's water is not only always changing forms, between liquid (rain), solid (ice), and gas (vapour), but also moving on, above, and in the Earth. This process is always happening everywhere. Click through this interactive diagram for more information.
