Water cycle

Water cycle


Water is a big part of the day because it can decide what you are doing for the day or what you
are not doing for the day, so it is a big part of life. Did you know that it covers 70% of the world's
surface. It also creates other creations such as rivers, lakes, valleys, ice caps on mountains and
more.  There are 4 main steps to a water cycle evaporation, condensation, precipitation and collection.


Evaporation 
Evaporation is when water is found in lakes, oceans, swamps, and soil, as well as in all living
creatures and plants. Then the heat is applied from the sun and it sees the water rise into the air.
the water molecules become excited and spread out across the sky to form into a nice and big
vapor cloud. 


Condensation
Condensation is when the water vapor has risen into that sky cools then  it comes into contact
with the cooler air found up high. The vapor becomes a cloud, which is pushed around the world
by moving air currents and winds. If the water vapor cools to anything above zero degrees it will
condense as water. Then it will start to turn into droplets, These tiny droplets will start to fall into one another and merge, producing a larger droplet. When a droplet is large enough, gravity
will pull it down at a rate that exceeds the updraft in the cloud, leading to the droplet falling out of the cloud and onto the ground below.


Precipitation
Precipitation is when the water has fallen into rain and is absorbed into the ground. Soil and other
porous materials can absorb great deals of water this way, while rocks and other harder
substances will only retain a small amount of water. When the water infiltrates soil, it will move in
all directions until it either seeps into nearby streams or else sinks deeper into what is known as
groundwater storage. 


Collection
After the water has fallen and the soil has become saturated, or the snow has melted, the water
follows gravity and falls down any hills, mountains, or other inclines to form or join rivers. This
process is known as the runoff and it is how water comes to rest in lakes and returns to the ocean.
The water falls according to the incline of the place from which it is falling, and when several
threads of water meet they form a stream.

There is no start or end to the water cycle, but for explanation purposes we will start at the sun.
Solar radiation from the sun heats the ocean and causes evaporation. This water vapor then
enters the atmosphere.
