Decomposition Reactions 1. Place approximately half a spatula full (roughly pea-sized) of copper(II) carbonate in a dry test tube. If you do not have a clean, dry test tube, ask your instructor for one. Do not try to dry a test tube during the laboratory period.
What Is the Asthenosphere? The asthenosphere is part of the upper mantle located below the crust of the earth. The asthenosphere boundary is primarily defined by temperature, and it starts when the crust heats up to 1300Â° C. At this temperature the crust begins to melt and move more as a liquid. The asthenosphere is important in plate tectonics, as convection currents slowly move the tectonic plates that lie above.
The asthenosphere is that part of the Earth which is viscous and undergoes ductile deformation and convection on a geological time scale. It is part of the upper mantle and is â¦ approximately 600 km thick laying below the lithosphere at a depth of around 100 to 200 km and it's base is around 700 km deep.he asthenosphere consists of many varieties of rock which is mostly in a semi molten condition. The temperatures in the asthenosphere reach levels high enough for most of the rock to become soft and plastic, capable of slowly moving while remaining in a solid state, while only about 10 percent is totally molten.
