The water cycle

The water cycle is a process that goes through land, sea and the atmosphere. The water gets recycled as the process continues changing between liquid, gas and solid. The different stages of the water cycle are evaporation, condensation, precipitation and runoff/ groundwater.

Evaporation happens when the sun heats heats the water and it changes to gas/water vapor. On hot days evaporation happens a lot faster because the sun is hotter so the water heats faster. Salt does not rise with the water vapour because it’s too dense and heavy to rise and that’s why rivers and lakes are freshwater.  After evaporation has happened the water vapour rises until it cools down enough to become condensation.

Condensation happens when the water vapour gets too cold. If the water vapour gets too cold on a cold day it comes down as snow. Water vapours merge to create droplets in the clouds. Clouds hold condensation as droplets until they get too heavy and falls  down as precipitation/rain. Runoff/groundwater happens when the precipitation seeps into the ground/ rivers and lakes.

Runoff/groundwater is the water when the precipitation seeps into the ground. Groundwater, goes into the aquifers via underground streams. Runoff happens when the water from precipitation runs down the mountain. Groundwater is fresh h2o.

The water cycle is a process that is very important for people to survive.
