SpletWe define the asthenosphere viscosity as the lowest viscosity in the upper mantle in a specific region. Generally, the temperature profile is the dominant variable to define … Spletlithosphere, rigid, rocky outer layer of the Earth, consisting of the crust and the solid outermost layer of the upper mantle. It extends to a depth of about 60 miles (100 km). It is broken into about a dozen separate, rigid blocks, or plates (see plate tectonics). Slow convection currents deep within the mantle, generated by radioactive heating of the …

SpletThe asthenosphere is part of earth 's mantle. It is about 100 km to 350 km under the surface. [1] It is the lower part of the upper mantle, and behaves as a hot viscous liquid. It consists of hot, weak material that can be deformed like silly putty. That means it is capable of gradual flow. Splet05. avg. 2024 · The asthenosphere is a layer of rock beneath the Earth's crust, where the Earth's solid crust and rocky upper mantle, or lithosphere, meet the lower layers of the mantle. You might already know the Earth is made of layers, like an onion. On the outside is the crust, a thin layer of solid rock covering the Earth's surface.

A) A portion of the atmosphere that blocks UV radiation B) A soft, low-velocity layer in the Upper Mantle C) The transition zone between the Mantle and the Outer Core D) The portion of the Hydrologic Cycle that describes how plants contribute their respiration B
SpletWe define the asthenosphere viscosity as the lowest viscosity in the upper mantle in a specific region. Generally, the temperature profile is the dominant variable to define regional viscosity. We approximate the mantle temperature profile as adiabatic with a thermal boundary layer at the top. SpletIn the classic definition the plate is defined thermally, by the geotherm-adiabat intersection, where the plate is the conductively cooling part of the mantle convection system. ... At relatively short geologic timescales, the low-viscosity asthenosphere promotes rebound of the tectonic plates owing to lake level changes, deglaciation, and ...
