6 Water Cycle The water on Earth now is the same water that s been on Earth since the beginning. The rain that falls on us is the same water that rained on the dinosaurs, King Tut, and George Washington. What makes that awesome feat possible? The water cycle. The water cycle is the process that re-circulates water so we can have bodies of water as well as clouds and precipitation. The first step of the water cycle is evaporation. About 85% of the water vapor in the air comes from water that evaporated from the oceans. The other 15% comes from evapotranspiration, which is a catch-all term for water that evaporates from over land. This includes water vapor produced by plants during transpiration, water from lakes, streams, puddles and soil moisture, direct evaporation of snow and even water vapor from the breath of animals. The second step of the water cycle is condensation. Now that the atmosphere is full of water vapor, that water vapor condenses into water droplets. Sometimes, like early in the morning, the water vapor condenses on the grass as dew and seeps back into the soil, ready to be evaporated again. But most of the water vapor condenses higher up in the air and forms clouds. Once the water droplets are in a cloud, two things can happen. Either the cloud will dissipate and the water droplets will become vapor again, or the cloud will grow and it will begin to precipitate. The third and final step of the water cycle is precipitation. Precipitation includes all water that falls from the sky, both in liquid and frozen form, which reaches the ground. Once the precipitation makes its way to the ground it can end up soaking into the ground, run off into streams and lakes, become snow cover, be used by plants, be inhaled by animals or fall directly back into the ocean. Then the water cycle can begin again and continue for millions of years to come. Aside from the above steps of the water cycle, there are also ways that water can be stored on Earth that play a role in the water cycle at various times throughout the year. Water can be stored in lakes, streams, glaciers, icebergs, and the ground. As precipitation falls towards the earth, some of the water seeps into the ground, a process known as infiltration. The amount of water that seeps into the ground varies with several factors such as duration, type, and strength of precipitation, type of soil, slope of the land, and land cover. The factors that impact infiltration also impact surface runoff. Runoff occurs when water flows across the ground surface. If no water is able to seep into the ground, the water will flow across the ground surface. This occurs many times near mountains as water flowing quickly down a mountainside is unable to be absorbed by the ground. If a certain type of soil does not absorb water very well or if the soil is already saturated, then the water remains on the surface. Clay is an example of a soil that absorbs water slowly in comparison to sandy soils. More runoff will occur over land with clay soil rather than land with sandy soil. Runoff can also occur during snowmelts from mountainsides.

7 Which water feature is often associated with condensation? A. Frozen lakes B. The ocean C. Clouds and fog D. Water vapor rising from plants Which series of processes cannot happen in the water cycle? A. Evaporation > condensation > precipitation B. Precipitation > runoff > evaporation C. Precipitation > infiltration > evaporation D. Runoff > precipitation > condensation Infiltration happens when. A. it rains and water runs along the surface to a nearby river B. water seeps into the ground C. there is too much condensation and it rains D. water is frozen on the surface After water is evaporated into the air, what is most likely to happen next? A. Water will eventually condense in the form of clouds or fog. B. Water will runoff into oceans and streams. C. It will rain, sleet, or snow. D. Water will used by the roots of plants.
