The earth has limited amount of water so we need to reuse it, the water keeps going around and around in “The Water Cycle” What do we know about the water cycle? Precipitation Transpiration Evaporation Condensation Run Off
Water droplets in clouds eventually become too heavy for the air to support and fall to the ground as rain, snow or sleet
Water evaporates from oceans, lakes, rivers, the upper layers of the soil, and from the leaves of the plants and bodies of animals.
Water vapor is released into the air by the leaves of plants. Plants transpire more on hot, sunny days.
Water vapor in the air gets cold and changes back into liquid, forming clouds. This is called condensation.
When water falls back to earth as precipitation, it may fall back in the oceans, lakes or rivers or it may end up on land. Ground water- When it ends up on land, it will either soak into the earth and plants and animals use to drink Surface water-Run over the soil and collect in the oceans, lakes or rivers where the cycle starts
As water seeps downward it carries dissolved chemicals deeper into the soil The chemicals may be required for growth and development of the plant
