This unit explores Earth systems and its resources that support life. Geological changes that occur to Earth systems at convergent and divergent boundaries can result in the creation of mountains, island arcs, earthquakes, volcanoes and seafloor spreading. Soils are a resource, formed when parent material is weathered, transported and deposited. The atmosphere is another resources, composed of certain percentages of major gases. Climate is influenced by the Sun's energy, Earth's geography and the movement of air and water. In subsequent units, we will examine how humans use natural resources and the impact on the environment.
Big Ideas: Interactions Between Earth Systems: Earth's systems interact, resulting in a state of balance over time. Energy Transfer: Most of the Earth's atmospheric processes are driven by input of energy from the Sun. |
