All About Water
Transcript of All About Water
What is the hydrologic cycle?
It describes the continuous movement of water on, above, and below the surface of Earth.
It is a cycle with no beginning or end and includes many different processes.
Water and energy are transferred through the hydrosphere, geosphere, and atmosphere.
The amount of water on Earth remains constant, but continuously changes forms as energy from the sun drives the cycle.
Liquid Water --> Water vapor (gas)
An INCREASE in energy from the sun creates heat which causes the water to rise into the atmosphere and becomes a gas (water vapor)
Similar to evaporation:
Liquid water --> water vapor (gas)
Process by which plants release water vapor into the atmosphere.
Water vapor (gas) --> liquid water
Clouds become visible when water particles combine with dust in the air
There is a LOSS of energy which creates cooling and condensing of water.
Occurs when no more water can be absorbed into the ground and gravity pulls it downhill.
Water flows over land, becomes rivers (which flow into the ocean) and the water cycle continues
Water vapor in the clouds condenses even more to form drops heavy enough that the clouds can no longer hold them.
It then either rains, hails, snows, sleets, etc.
Water fills the little spaces or holes in Earth
It then becomes groundwater
