Quarter 1 Concepts Cycle 1 Identify the components of earth's crust Compare and contrast the components of earth's inner and outer cores Identify the location of convection currents that result in movement of tectonic plates Explain why similar fossils are found on different continents Cycle 2 Determine how the direction of a convection current effects tectonic plate movement Sequence the steps of new land formation through seafloor spreading (3) Identify the effects of different types of plate boundaries on earth's crust Relate plate boundary movements to their resulting landforms, including: mountains, faults, rift valleys, trenches, volcanoes (6) Sequence the stages of erosion and deposition Identify the stage of sediment based on its shape, e.g., round, jagged edges (2) Identify causes for earthquakes Cycle 3 Determine the environmental changes that took place over time based on a diagram of fossil and rock layers Identify changes in the fossil record due to earth's processes, e.g., volcanism, erosion Identify the conditions that resulted in coal beds Identify a type of volcano based on its formation and composition
