What is the The density of the asthenosphere?
The density of the Earth's asthenosphere is 4 gm/cm^3.
What is the consistency of the asthenosphere?
The viscosity of the mantle is estimated to be about 10^21 poise (10^19 Pascal seconds).
What causes hot plasticlike rocks in the asthenosphere to rise toward the earths surface?
The rock in a rising convection current is hotter and more buoyant than the surrounding rock, causing it to rise.
Why does ocean crust far from a mid-ocean ridge subside?
It becomes more dense as it cools, until its density is greater than the asthenosphere below it.
What is the partially melted part of earth that carries the crust?
It is called the asthenosphere.
What is the The density of the asthenosphere?
The density of the Earth's asthenosphere is 4 gm/cm^3.
What are the main causes of convection in the asthenosphere?
Density and tempurature.
What kind of energy changes density in the asthenosphere?
thermal energy !
What is the consistency of the asthenosphere?
The viscosity of the mantle is estimated to be about 10^21 poise (10^19 Pascal seconds).
What do scientists believe in that cause hot plasticlike rock in the asthenosphere to rise toward Earth's surface?
density
What is the general term of the up and down forces between the crust and the mantle?
Isostasy is the balance and buoyancy of the Earth's crust floating on the asthenosphere, the top layer of the mantle. The asthenosphere, like Silly Putty, adjusts to the different densities and thicknesses of the crust. For instance, glaciers add weight (density, really) to the surface of the Earth. The added density depresses the flexible crust down into the asthenosphere, which, in turn, responds by slowly flowing away from the added burden. As the glaciers melt, the crust under them rebounds (rises), and the asthenosphere flows back, returning to its normal level.
Is it true or false that the asthenosphere floats on the lithosphere?
Because of something called Isostacy-the gravitational equilibrium between lithosphere and asthenosphere, such that plates "float" at an elevation that dependes on the thickness and density. EX. Think floating ice cubes
Why does ocean crust from a mid-ocean ridge subside?
It becomes more dense as it cools, until its density is greater than the asthenosphere below it.
Most deformable layer of the Earth?
