The Water Cycle Exam Questions And Answers

The Water Cycle Exam Questions And Answers What is the driving force behind the water cycle? - CORRECT ANSWER he sun Which stage of the water cycle are clouds formed? - CORRECT ANSWER condensation Describe a water drop in the water cycle that involves evaporation. - CORRECT ANSWER Water heats up, changes to water vapor and evaporates, rises into the sky. It cools, condenses, turns back into liquid water forming clouds. Then it falls back to earth as precipitation and runs down hills or mountains during runoff and returns to lakes and oceans. *precipitation - CORRECT ANSWER water that falls to the ground in the form of rain, sleet, snow, hail, or freezing rain Describe a water drop as it goes through the water cycle that involves transpiration. - CORRECT ANSWER Plants heat up due to sun's energy. Water heats up changes to water vapor and leaves the plants and rises into the sky. Then it follows the rest of the water cycle. Explain the process of evaporation. - CORRECT ANSWER Liquid water gains energy from heat and changes states of matter into a vapor. Because vapor is less dense it rises into the sky. Explain the process of transpiration. - CORRECT ANSWER As the plant heats up, it gains heat energy from the sun, water that is absorbed changes states of matter into water vapor and is released from the plant and rises into the sky. Explain the process of condensation. - CORRECT ANSWER Water vapor cools as it rises higher into the atmosphere and turns back into liquid water. Water droplets come together to form clouds. Explain run off. - CORRECT ANSWER As precipitation falls, due to the force of gravity, it runs down hills and mountains back into other bodies of water. It can also seep into cracks in the ground and collects in aquifers under the ground. What force cause run off? - CORRECT ANSWER gravity Compare and contrast evaporation and transpiration. - CORRECT ANSWER Evaporation and transpiration are both examples of water changing states from a liquid to a gas and rising into the atmosphere. Evaporation happens from bodies of water and transpiration happens from plants. What role does changing temperature play in the water cycle? - CORRECT ANSWER Water cooling or losing heat energy causes condensation and water gaining heat energy or heating up causes evaporation. How is the water cycle an example of matter changing states. - CORRECT ANSWER Due to gaining or losing heat energy from the sun, water changes from liquid water into gas (evaporation) and from water vapor, gas, into liquid water (condensation) Explain how water is recycled on earth. - CORRECT ANSWER The Water Cycle Explain 2 things that can happen to water after the precipitation stage. - CORRECT ANSWER Water can return to bodies of water like lakes and oceans or it can seep into the ground and return to aquifers. List 4 types of precipitation. - CORRECT ANSWER rain, sleet, snow or hail *condensation - CORRECT ANSWER Water vapor cools as it rises higher into the atmosphere and turns back into liquid water because it loses heat energy; Water droplets come together to form clouds
