The Grade 6 Earth Science Unit focuses on plate tectonics and addresses the California Science Standards for 6th grade for the topic of plate tectonics and Investigation and Experimentation. By the end of the unit students will know: Plate tectonics accounts for important features of the Earth’s surface and major geological events. Evidence for plate tectonics is derived from the fit of continents; the location of earthquakes, and midocean ridges; and distribution of fossils, rock types, and ancient climatic zones. The Earth is composed of several layers: a cold, brittle lithosphere, a hot, convecting mantle; and a dense, metallic core. These layers have different densities, compositions and temperatures (energy). Lithospheric plates the size of continents and oceans move at rates of centimeters per year responding to convection currents in the mantle. Geologic events, such as earthquakes and mountain building, result from movement of the plates. Earthquakes are sudden motions along the breaks in the crust called faults and that volcanoes and fissures are locations where magma reaches the surface. Epicenters of earthquake can be determined. The effects of the earthquake on any region varies, depends on the size of the earthquake, the distance of the region from the epicenter, the local geology, and the type of construction in the region. Every plate boundary is a dynamic place resulting in changes to the earth’s surface. Mountains and sea floor trenches can be explained if you understand the possible combinations of crust movement at the boundaries. When two continental plates collide, large mountain ranges (like the Himilaya) are formed. Because an oceanic plate will subduct, deep sea trenches result. Even transform boundaries involve great pressure that can alter land formations and result in small mountain ranges. Major features of California geology, including the Channel Islands, are the result of plate tectonics.
