Explain the water cycle. What can cause ice to melt and water to freeze?
When the water vapor takes place, the precipitation that comes down is either rain snow sleet or hail. When the precipitation evaporate it’s a gas called water vapor. After the evaporation the water vapor goes back into the clouds and condenses. Heat causes ice to melt. Very cold air causes water to freeze and becomes ice.
