2 Student ExpectationAnalyze the effects of weathering, erosion, and deposition on the environment in ecoregions of Texas.
3 WeatheringThe breakdown of the materials of Earth’s crust into smaller and smaller pieces.
4 Physical WeatheringProcess by which rocks are broken down into smaller pieces by external conditions.Types of Physical weatheringFrost heaving and ice wedgingPlant rootsFriction and impactBurrowing of animalsTemperature changes
23 Mass Movements Landslides, mudslides, slump and creep landslide clip.mpeg
24 DepositionThe dropping of sediment when an agent of erosion, such as gravity, a glacier, wind, or water, loses its energyHorizontal sorting – the sediments that were once carried down the stream are dropped off from largest to smallest.Graded bedding – the smallest sediments are also dropped to the bottom last
