1) ? How does removing energy affect water a) If you have to change water vapor to liquid, you will have to remove energy or cool it. This process is called condensation. b) Water in the liquid form will freeze to solid when energy is removed. c) Water evaporates. Evaporation is the process by which a liquid, such as water, changes into a gas. 2) Explain water cycle a) : Water enters the atmosphere b) evaporation, thermal energy from the sun is absorbed. c) Water enters the atmosphere through the processes of evaporation, transpiration and respiration. During the process of evaporation, thermal energy from the sun is absorbed. 3) How does gravity contribute to the water cycle a) Precipitation is a part of water cycle where rain, snow, sleet or hail fall to the ground. With no gravity this would not be possible. With no precipitation water cycle will be incomplete. b) Gravity helps the water to flow downhill. Any form of precipitation falls down because of gravity. c) More than 75 percent of precipitation falls into the ocean. 4) Why do some clouds rain a) Some droplets move through warm layers of air, and they evaporate before they fall as precipitation. b) Some droplets move through moist layers of air, and they join and grow bigger till they fall to Earth as precipitation. c) The water droplets that make up clouds are pulled toward Earth’s surface by gravity. 5) Earth receives energy from the sun through ____________. a) Radiation b) convection c) condactition 6) What is the process of liquid changes to the gas at the surface ? a) boiling b) evaporation c) condensation
