Erosion
When the smaller pieces are moved by wind or water it is called erosion. Erosion is a visible process that may happen quickly or slowly. So, weathering is making smaller pieces and erosion is moving the pieces. Both weathering and erosion happen continuously.
Mountains are built through a general process called “deformation” of the crust of the Earth. Deformation is a fancy word which could also mean “folding”. An example of this kind of folding comes from the process described below.
When two sections of the Earth’s lithosphere collide, rather than being subducted, where one slab of
lithosphere is forced down to deeper regions of the Earth, the slabs pile into each other, causing one or both slabs to fold up like an accordion. This process elevates the crust, folds and deforms it heavily, and produces a mountain range. Mountain building and mantle subduction usually occur together.

Classroom Implementation
he following videos were filmed during lesson implementation by teachers in the Orange County Cohort. Please feel free to use these videos to better visualize how the lessons can look in an actual classroom setting. Note that we do not intend for you to try to recreate the lessons exactly as you see them here.
