<span>A head-on shot rarely results in a clean kill, ruins meat, and provides a means for the animal to best detect the hunter. It is difficult to achieve this shot, which often results in the deer hearing the gun and running away (thus, detecting the hunter).

The asthenosphere lies 80-200km below the surface under the lithosphere. Convection also occurs in the asthenosphere. The asthenosphere is mostly made of up rock material (magnesium and iron silicates). The asthenosphere makes up 6% of the mantle and lets the lithosphere move.
Best of Luck!
You would add H+ ions if you added an acid. Thus lowering the pH.
