Why is oceanic crust younger than the continental crust? What is the density of the lithosphere and asthenosphere? Why do earthquakes occur in the lithosphere? How do convection currents in the mantle drive plate tectonics? How does magma form over an active subduction zone?
How is continental crust different from oceanic crust? What are the characteristics of the Earth's crust, mantle, and core? What is the density of the lithosphere and asthenosphere? How does oceanic crust form? How dense is the upper mantle?
oceanic crust. To explain the remarkable differences in the morpho-structural setting of the western Pacific-Antarctic plate boundary, we propose that oceanic lithosphere responds in different ways as a function of the age of the crust involved in the tectonic reorganization and is conditioned by ...

How are ocean trenches formed? Learn how the movement of tectonic plates form the deep ocean trenches and see examples of some of the more famous trenches. Examine how life still thrives in the deep ocean trenches and how vital that life is to understanding human evolution. ...
Thermoelastic stress: How important as a cause of earthquakes in young oceanic lithosphere 9 - Bratt, Bergman, et al. - 1985 () Citation Context ...even if the motions do not, or change little. If thermal stresses play an important tectonic role, one should expect to see a time window ...
How does the strength of the continental crust vary with depth? Layers of the Earth: There are three layers of the Earth. There is the crust (the top level), the mantle in the middle, and the core at the very center of the Earth. The layers have different levels of pressure that inf...
Just as oceanic crust is formed at mid-ocean ridges, it is destroyedin subduction zones. Subduction is the important geologic process in which a tectonic plate made of dense lithospheric material melts or falls below a plate made of less-dense lithosphere at a convergent plate boundary. ...
1- Lithosphere or Crust The crust which is also known as the lithosphere is located in the outermost part of the earth. The average thickness of the crust is about 33 km; it is thicker under the land (35-40 km, under the Tibetan Plateau 70 km) and thinner on the ocean base (8-...
is considerably less dense than the asthenosphere. It gradually moves away from the divergent boundary and gets cooler (through conductive cooling) as well as denser. The higher density of oceanic lithosphere, compared to that of the asthenosphere, allows it to subside deep into the mantle at the...
