Hi! My name is Nancy and we're going to learn about the Hydrological cycle today! This is a process in which water transforms states and is recycled throughout Earth.
It begins with the evaporation of water which is the process in which liquid turns into vapor. Water can evaporate from oceans, rivers, or any collection of water.
This water vapor also comes from transpiration which is when leaves exhale water vapor.
This evaporated water is lifted by the air into the atmosphere and cools down and condenses into clouds.
As the clouds grow heavier and heavier, they eventually release the water as precipitation, which can be rain , snow which is frozen ice crystals, sleet which is a mix rain and snow, or hail which is pellets of ice.
The rain causes the water to return back to Earth. It can create runoff which is just when water drains from surfaces on Earth and can find its way back into the oceans, lakes and streams. It can also get absorbed into the ground and can become groundwater which is water held underground.
The water can be stored in things called reservoirs which include the atmosphere. the oceans, and snow and ice.
And then this cycle starts all over again, continuously circling the water from the Earth to the atmosphere and will never stop!
