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.
Introduction. The asthenosphere is the layer of the Earth that lies below the lithosphere. It is a layer of solid rock that has so much pressure and heat the rocks can flow like a liquid.The rocks are less dense than the rocks in the lithosphere.ocks in upper mantle. The rocks in the upper mantle can be part of the lithosphere or the asthenosphere. Lithosphere rocks are solid and rigid. Rocks below the lithosphere flow and break apart.
