WA.4. Earth and Space Science
ES2. Earth Systems, Structures, and Processes
6-8.ES2. Cycles in Earth Systems: In prior grades students learned how Earth materials change and how they can be used for various purposes. In grades 6-8 students learn about planet Earth as an interacting system of solids, liquids, and gases. Solar energy powers the water cycle and drives the weather system and ocean currents. Energy from within the planet drives the rock cycle and moves huge plates on the Earth's surface, causing earthquakes and volcanoes. The landforms we see today result from processes that build up and break down Earth structures. These fundamental ideas will enable students to understand the history of their planet, Earth processes occurring today, and future geologic events.
6-8.ES2B. The Sun is the major source of energy for phenomena on Earth's surface, such as winds, ocean currents, and the water cycle.
6-8.ES2B.2. Students are expected to describe the role of the Sun in the water cycle.
6-8.ES2C. In the water cycle, water evaporates from Earth's surface, rises and cools, condenses to form clouds and falls as rain or snow and collects in bodies of water.
6-8.ES2C.1. Students are expected to describe the water cycle and give local examples of where parts of the water cycle can be seen.
