Unit 6: Geology: Plate Tectonics Tectonic Plate Movement
... How would the behavior of two plates that are said to be along a convergent boundary best be described? Can you visibly watch the motion of two plates colliding into one another. If so, how? If not, why? What are the three possible types of convergences that can occur when two tectonics plate collid ...

Towards a better understanding of hot spot volcanism
... upsurge of magma from the mantle is facilitated. When these magmatic uprisings occur at a subduction zone, where one tectonic plate plunges under another, they give rise to volcanic massifs such as the Andes cordillera. Other volcanic chains are formed along oceanic ridges, submarine regions of ocea ...

Intensity Scale
... The Mercalli Scale is a measure of the effects of an earthquake at a particular place and depends not only on strength (magnitude) of a quake, but also the distance from the place of origin and the local geology at the observation point. A given event will have only one magnitude, but many intensity ...

Melting of the mantle
... Further dehydration takes place at greater depths as other hydrous phases become unstable, including amphibole at about 3 GPa. The slab crust is successively converted to blueschist, amphibolite, and finally anhydrous eclogite as it reaches about 80-100 km depth. In most (mature) arcs, the temper ...

Geology
Geology (from the Greek γῆ, gē, i.e. ""earth"" and -λoγία, -logia, i.e. ""study of, discourse"") is an earth science comprising the study of solid Earth, the rocks of which it is composed, and the processes by which they change. Geology can also refer generally to the study of the solid features of any celestial body (such as the geology of the Moon or Mars).Geology gives insight into the history of the Earth by providing the primary evidence for plate tectonics, the evolutionary history of life, and past climates. Geology is important for mineral and hydrocarbon exploration and exploitation, evaluating water resources, understanding of natural hazards, the remediation of environmental problems, and for providing insights into past climate change. Geology also plays a role in geotechnical engineering and is a major academic discipline.
