  1. The Water Cycle

  2. What makes water so unique?

  3. Evaporation • Heat energy from the sun causes water in puddles, streams, rivers, seas or lakes to change from a liquid to a water vapor. • Evaporation –the process where a liquid, in this case water, changes from its liquid state to a gaseous state.

  4. Transpiration • Transpiration is the process by which plants lose water out of their leaves.  • Transpiration gives evaporation a bit of a hand in getting the water vapor back up into the air. • Transpiration –As plants absorb water from the soil, the water moves from the roots through the stems to the leaves. Once the water reaches the leaves, some of it evaporates from the leaves, adding to the amount of water vapor in the air. This process of evaporation through plant leaves is called transpiration.

  5. Condensation • Water vapor collects in clouds. As the clouds cool the water vapor condenses into water drops. • This is called condensation. • These drops fall to the earth as rain, snow or hail. • Condensation –the opposite of evaporation. Condensation occurs when a gas is changed into a liquid.

  6. Precipitation • Precipitation is when water falls to the earth from clouds. Mainly as rain, but sometimes as snow and hail. • Precipitation –when the temperature and atmospheric pressure are right small droplets of water form in clouds.

  7. Infiltration • Infiltration is where rain water soaks into the ground, through the soil and underlying rock layers.

  8. Accumulation • Accumulation –the build-up of water in one place over a course of time.

  9. Run-Off • Run-Off –Much of the water that returns to earth as precipitation runs off the surface of the land, and flows down hill into streams, rivers, ponds, and lakes.
