Introduction Weathering Mechanical Biological Chemical Decomposed Granite Erosion Falls, Slides, and Flows Complex Movements Creep Introduction General Review: a regional view Earth has 2 levels Earth has 2 types of rock Earth has 2 processes Construction and Destruction Over the course of geologic time these 2 are in balance Tectonics: the study of earth processes which result in the creation and deformation of magma and rock This builds the earth as we know it (videodisc of mountains) The destructional processes are covered in &quot;The Hydrosphere&quot; This stuff can be mighty impressive Carve valleys (get videodisc - rivers and glaciers) Wash to sea (beach shots with sand/gravel) The basic idea: the earth takes what it builds and puts it in the ocean (overhead) But first the earth has to break it up because the mountains are too big to move in one piece Surface Weathering Mechanical (physical) weathering Smaller pieces / same stuff Fracturing and Abrasion Like the difference between a hammer and sandpaper Results in clastic sediments Sands to conglomerates Lots of methods Rocks in river Rocks falling Ice - the big one Cold areas with large daily temperature fluctuations Ice wedging: expands 10% upon freezing Can exert up to 4,900,000 lbs./in^2!!
