There are threemain types of rocks: sedimentary, metamorphic and igneous. Each are formed in a different ways. Sedimentary rocks contain rounded grains in layers. Chalk, shale and limestone are examples of sedimentary rocks. This activity is a very simple demonstration of how howsedimentary rocksar...
Differential erosion is erosion that occurs at varying speeds, due to differences in the resistance and hardness of materials; soft rocks erode faster than hard rocks. Niagara Falls formed this way when a hard, upper layer of limestone eroded more slowly than a lower, softer shale. ...
Shale:Shale is a sedimentary rock made up of fine-grained particles like clay and silt. Shale weathers relatively easily due to its fine-grained structure and high clay content. Physical weathering causes it to break down into thin flakes, and chemical weathering transforms its minerals into clay...
Cliffs of Moher are the most popular tourist attraction in Ireland. It draws around one million visitors each year. The Cliffs of Moher range from 120 to 214 meters in height above water level and lies along 8 kilometers. It is made ofsedimentary rock, especially shale and sandstone. ...
These are composed of fragments of rocks which were transported from the source by mechanical means, deposited and subsequently compacted,e.g.sandstone, conglomerate and shale. Chemical sedimentary rocks: These is formed when chemicals dissolved from the rocks are carried in solution to other areas ...
HARBIN, Sept. 5 (Xinhua) -- In the hills about 35 km southwest of Baoqing County in northeast China's Heilongjiang Province, there is a small lake sparkling vivid green in the sunshine, just like an emerald. It's hard to believe it was once an abandoned shale mine pit before seeing th...
In contrast, the in-situ formed veins and slip surface exhibit H = 0.4–0.5, which is deemed representative for in-situ fractures. These results are discussed in relation to the shale microstructure and linear elastic fracture mechanics theory. The data imply that the Hurst roughness ...
