The Alaskan way Viaduct will collapse if an earthquake happens, but that earthquake will take many steps. These steps will got through the layers of the earth. The layers are stacked on top of eachother, like the liquids in the “Density Column lab”. The layers are inner core, outer core, mesosphere, asthenosphere, and lithosphere(upper rigid mantle, continental crust, and oceanic crust). The earth's compositional layers are inner core, outer core, mantle, and crust. The inner core radiates heat, the inner core is always giving out heat. the heat goes through the outer core and mesosphere and asthenosphere, asthenosphere is where convection currents happen. the temperature from the heat coming from the inner core makes the convection currents
