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 a layer of plastic-like rock that makes up one of the three major parts of the Earth's interior. It is found roughly 40 miles (70 km) under the surface of the Earth.The radius of the Earth itself is about 3950 miles (6370 km) from the surface to the center of the planet. The asthenosphere extends from roughly 40 miles under the surface to somewhere around 155 miles under the surface.This means that the asthenosphere makes up about 110 miles of the 3950 mile radius of the Earth.t is found roughly 40 miles (70 km) under the surface of the Earth. The radius of the Earth itself is about 3950 miles (6370 km) from the surface to the center of the planet.
