Clouds are an important part of the water cycle. The
water cycle is the movement of water from the Earth into the
sky and. Then back down to Earth again. Did you know that
over 70% of the Earth is covered in water? Water on Earth is in the form. Of salt
water (97%), the water that is found in the oceans and, saltwater lakes and fresh
water (3%), the water that is. Found in rivers ponds lakes,,,Streams and
underground. The sun heats water on the surface of the Earth and causes, it to
evaporate. Evaporation is the. Process when water moves from being a liquid to
being vapor. Water vapor is made up of tiny water droplets in the air. Water. Can
also move into the air through transpiration. Transpiration is the movement of
water out of plants, During photosynthesis.Plants make oxygen and water. Water
then moves out of tiny holes on the leaves and into the air. The water vapor rises
up. Into, the atmosphere and as it cools it, condenses. When the water vapor
condenses it forms clouds. Precipitation happens. When so much water vapor
condenses that the air cannot hold it anymore. The clouds get so heavy that
.Some of the water must fall back down to Earth, as rain snow sleet or, hail.
There are many different types of, clouds. The type of cloud depends on
how high up in the atmosphere the water condenses. The atmosphere is the
blanket of air that. Covers the Earth.
