Water on Earth
INFORMATION ABOUT THE SMALL IDEA
Earth > Earth materials and structure > Water on Earth
Most of the Earth’s surface is covered with water. It moves through Earth's hydrosphere, geosphere and atmosphere in different ways (e.g. evaporation or transpiration) and shapes Earth's weather and surface. Water is the largest energy reservoir on Earth.
Connection to Big Idea about energy: Water is a great reservoir of energy. It can absorb, store and release huge amounts of energy. Mankind is yet to take full advantage of this reservoir.
Connection to Big Idea about the cell: Water was the medium where the first cells appeared and later combined into multicellular organisms, thus starting life on Earth.
Connection to Big Idea about evolution: Water's unique properties, like expanding upon freezing, are among the key factors for the existence of life on the planet. Ice floats on top of liquid water as a result of its hexagonal packing within its crystalline structure. This makes seas, lakes and rivers freeze from top to bottom, allowing underwater organisms to survive even when the surface is frozen.
