Saprolite is a particular example of a residual soil formed from the transformation of granite, metamorphic and other types of bedrock into clay minerals. Often called weathered granite, saprolite is the result of weathering processes that include: hydrolysis, chelation from organic compounds, hydration and physical processes that include ...
The rows formed slow surface water run-off during rainstorms to prevent soil erosion and allow the water time to infiltrate into the soil. Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination
Breaching levees to reconnect streams to their floodplains can be an effective form of restoration as well. On the Cosumnes River in central California, for example, the return of seasonal flooding to the floodplain as a result of levee breaching was found to result in the reestablishment of primarily native riparian plant communities.
Cheddar Gorge is a limestone gorge in the Mendip Hills, near the village of Cheddar, Somerset, England. The gorge is the site of the Cheddar show caves, where Britain's oldest complete human skeleton , Cheddar Man , estimated to be 9,000 years old, was found in 1903. [ 1 ]
The Olduvai Gorge Museum, located 5 km beyond the monument, is situated on the rim of the gorge at the junction of the main gorge and the side gorge. As one of the largest onsite museums in Africa, the museum provides educational exhibits related to the gorge and its long history.
Niagara Gorge is an 11 km (6.8 mi) long canyon carved by the Niagara River along the Canada–United States border, between the U.S. state of New York and the Canadian province of Ontario. [1] It begins at the base of Niagara Falls and ends downriver at the edge of the geological formation known as the Niagara Escarpment near Queenston, Ontario ...
If the initial impact of rain droplets dislodges soil, the phenomenon is called rainsplash erosion. If overland flow is directly responsible for sediment entrainment but does not form gullies, it is called "sheet erosion". If the flow and the substrate permit channelization, gullies may form; this is termed "gully erosion".
Letchworth State Park is a 14,427-acre (5,838 ha) New York State Park located in Livingston County and Wyoming County in the western part of the State of New York. [1] [5] The park is roughly 17 miles (27 km) long, following the course of the Genesee River as it flows north through a deep gorge and over several large waterfalls. [6]
