It explains the classification of clastic sedimentary rocks based on clast size, roundness, and sorting. The page also touches on other types of sedimentary rocks, including chemical and biochemical sedimentary rocks like limestone and chert.
This page highlights the importance of freshwater in ecosystems and the water cycle. It describes streams and rivers as vital transporters of eroded materials, with streams varying in size and speed. ...This page highlights the importance of freshwater in ecosystems and the water cycle. It describes streams and rivers as vital transporters of eroded materials, with streams varying in size and speed. The page details how streams carry materials through different loads and create floodplains and levees, while rivers deposit sediments forming deltas and alluvial fans. Deltas occur where river velocity decreases at ocean edges, and alluvial fans develop in flat, arid areas.
