materials in the hydrosphere

The hydrosphere is the layer of Earth that includes all waters of the planet, this includes oceans, seas, rivers, lakes and waters. This layer differentiates us from other planets. Scientists estimate that the hydrosphere contains about 1.36 billion cubic kilometers of water in its liquid state, which covers the topography of the Earth. In the hydrosphere can find water in three states: solid (ice), liquid and gas (clouds). The second most common form of water ice. Remember that water is a vital element for the existence of all living organisms, it also helps regulate the temperature of our planet. Hydrosphere was formed millions of years ago, the product of volcanic emissions, which were more frequent in these times. The vapor condenses into clouds, which then caused by torrential rains for millions of years
