| In the Science unit, "How Landforms Change", students employed a number of scientific processes: making models, interpreting and comparing data, observing, measuring, ordering, inferring and hypothesizing. The overall concept for this study is that as structures of Earth's crust break down, new structures form. One of the subconcepts to this is that the outermost of Earth's four layers is the crust, where all landforms are found. As part of this, we have looked at how the Earth's crust is made of layers of rock (sedimentary, igneous, metamorphic). We'll also look at how movement within Earth's crust builds and changes landforms. Some of the lessons around this topic will examine that: the crust is formed of separate plates that float on the mantle; the highest mountains on the planet have been formed by the collision and folding of crustal plates; as an oceanic plate slides under a continental plate, magma can be forced to the Earth's surface. |
