Wegener could not adequately define a process that could account for the observed movement. Petroleum, metals and groundwater often concentrated at these geologic structures. Rock originally laid down as horizontal layers due to settling of sediment. The youngest layers are therefore on top. This episode looks at the structure and formation of minerals that make up the Earth.
Minerals are natural inorganic solid materials of the Earth arranged in a crystalline structure.
3-D crystal lattice held by chemical bonds. Charged ion combines with opposite charge to neutralize. Crystal growth is accomplished by repeated pattern, results in shape and physical properties. Rare metallic minerals often precipitate from hydrothermal water. Revealed This episode gives an overview of the mechanisms and impact of landslides and other types of mass movement of earth.
