The Water Cycle

• What is the water cycle?

  • The continuous movement of water within the Earth and atmosphere
  • Involves processes like evaporation, condensation, precipitation, and infiltration
• What is an abiotic factor?

  Abiotic factors are non-living components that affect ecosystems.
• Why is water considered an abiotic factor in ecosystems?

  Because it is a non-living component that affects communities.
• Where is most of the water on Earth found?

  Most of the water on Earth is found in the oceans.
• What causes water to evaporate from the surface of the sea?

  Energy from the Sun causes the water to evaporate.
• What happens to water vapor when it cools down?

  It condenses to form clouds.
• What is precipitation?

  Precipitation includes rain, snow, hail, and sleet.
• What type of water is contained in precipitation?

  All forms of precipitation contain fresh water.
• What happens to water after it hits the ground?

  Some evaporates, some forms aquifers, and some becomes rivers or streams.
• Where does the water in rivers and streams eventually drain?

  The water in rivers and streams eventually drains back into the sea.
• How do plants contribute to the water cycle?

  • Plants take up water through their roots
  • Water moves up the plant in the xylem
  • Water vapor is released through stomata in leaves (transpiration)
• How do animals participate in the water cycle?

  Animals take in water by drinking and through food, and release it in urine and exhalation.
• What is transpiration in plants?

  • The process of water movement through a plant
  • Water is absorbed by roots, moves up through the xylem, and is released as vapor through stomata
