The astenosphere plays a key role in the plate tectonics theory because it is the one that provides the high temperatures, high pressure, and magma, that are the ones responsible for cracking up the crust on the surface.
The astenosphere, with the ability to crack the crust on the surface of the planet is creating the continental and oceanic tectonic plates, and it also provides the push force from bellow so that they can move across the globe and thus be creating the landscape on the planet.
Acid rain is found in Sweden and is caused by air pollution in Britain and other countries of Europe. The pollution produced in Britain ends up mostly in Scandinavian countries- countries of northern Europe including Sweden, Norway and Denmark. In the USA, the winds blow air pollution to certain areas in Canada.
Acid rain has terrible effects on water life. Thousands of lakes in Scandinavia have no more life in them. They have received so much acid rain for so many years that life has been snuffed out and nothing can survive in these waters.
