The document discusses the processes of rock weathering including physical, chemical, and biological weathering. It describes how different factors like climate, rock type, topography, vegetation, and human activities influence the rate of rock weathering. The main weathering processes gradually breakdown and decompose rocks at the surface, producing sediments and resulting in lower topography over long periods of time.
14. Products of Weathering Type of weathering Product of weathering and erosion Type of sediment ultimately deposited Mechanical weathering Fragments containing the same minerals as the original rock (e.g. grains of quartz from a granite) Clastic sediments and sedimentary rocks (e.g. sand and sandstone) Chemical weathering New solid mineral particles formed by chemical reactions during weathering (e.g. Clay minerals) Material dissolved in water (e.g. Calcium ions) Chemical and biological sediments (e.g. limestone and rock salt)
