The graham cracker was inspired by the preaching of Sylvester Graham, who was part of the 19th-century temperance movement.He believed that minimizing pleasure and stimulation of all kinds, including the prevention of masturbation, coupled with a vegetarian diet anchored by bread made from wheat coarsely ground at home, was how God intended people to live, and that following this natural law ...
Earth's crust and mantle, Moho discontinuity between bottom of crust and solid uppermost mantle. The Mohorovičić discontinuity (/ ˌ m oʊ h ə ˈ r oʊ v ɪ tʃ ɪ tʃ / MOH-hə-ROH-vih-chitch; Croatian: [moxorôʋiːtʃitɕ]) [1] – usually called the Moho discontinuity, Moho boundary, or just Moho – is the boundary between the crust and the mantle of Earth.
Volcano tectonics is a scientific field that uses the techniques and methods of structural geology, tectonics, and physics to analyse and interpret physical processes and the associated deformation in volcanic areas, at any scale. [1] These processes may be 1) magma-induced or, conversely, 2) control magma propagation and emplacement. In the ...
The alpine geology with its theory of thrusting (as geosyncline hypothesis; today's thrust tectonics) accepted horizontal movements. ( Suess 1875 ) cited in ( Holmes 1929a ) 1848 Arnold Escher shows Roderick Murchison the Glarus thrust at the Pass dil Segnas.
Surface map of oceanic crust showing the generation of younger (red) crust and eventual destruction of older (blue) crust. This demonstrates the crustal spatial evolution at the Earth's surface dictated by plate tectonics. Earth's crustal evolution involves the formation, destruction and renewal of the rocky outer shell at that planet's surface.
This understanding of the dynamics of the stress field can be linked to important events in the geologic past; a common goal is to understand the structural evolution of a particular area with respect to regionally widespread patterns of rock deformation (e.g., mountain building, rifting) due to plate tectonics.
Seismotectonics is the study of the relationship between the earthquakes, active tectonics and individual faults of a region. It seeks to understand which faults are responsible for seismic activity in an area by analysing a combination of regional tectonics, recent instrumentally recorded events, accounts of historical earthquakes and geomorphological evidence.
"Neotectonics is the study of young tectonic events which have occurred or are still occurring in a given region after its orogeny or after its last significant tectonic set-up [...] The tectonic events are recent enough to permit a detailed analysis by differentiated and specific methods, while their results are directly compatible with ...
