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. Evidence of a history of landslide activity, the strength of material, etc. are investigated for evidence of mass wasting before developing land. Grading, drainage and vegetation can help make the land suitable for development.
