We learned that the water cycle is a process that moves water between Earth’s surface and the atmosphere. The energy from the sun changes the liquid water on Earth to a gas in a process called evaporation. We also reviewed the processes of condensation and precipitation. We learned that water that cannot soak into the ground and flows across Earth’s surface is runoff. We learned that an aquifer is a body of rock that stores groundwater. We made a model of the water cycle and studied the process. We saw that landform used only one quarter of the area. We saw that runoff collects rock and sand from mountains moving it to the ocean. We created a book on the water cycle. We learned that water covers about 75% of the Earth and the Sun is the energy that drives the water cycle. We labeled each step in the water cycle including evaporation, condensation, and precipitation. Then we learned that transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released in the atmosphere. Transpiration is essentially evaporation of water from plant leaves.
