In the 1960s, scientists developed a revolutionary theory called plate tectonics. Plate tectonics holds that the lithosphere, a layer of rigid material composed of the outer crust and the very top of the mantle, is divided into seven large plates and several more smaller plates. This sort of magma production is called subduction zone volcanism. 2  If the plates collide and neither plate can subduct under the other, the crust material will just crumple, pushing up mountains. 3  This process does not produce volcanoes.
Now, we have known the symptoms and causes of atrophic kidney, and then the last but most important thing is to find the treatment. Since poor blood supply and nephron loss is the root cause of atrophic kidney, the most effective treatment is to increase the blood flow in the kidney and repair kidney function. You can learn more about this treatment from âAn Effective Treatment for Atrophic Kidneyâ.
