Because CaSO4 is somewhat soluble in water, significant damage to the structure can result. The biological effects of acid rain are more complex. As indicated in Figure 4.8.2 4.8. 2, biological fluids, such as blood, have a pH of 7–8. Organisms such as fish can maintain their internal pH in water that has a pH in the range of 6.5–8.5.

Weathering is the process that changes solid rock into sediments. With weathering, rock is disintegrated into smaller pieces. Once these sediments are separated from the rocks, erosion is the process that moves the sediments away from it’s original position. The four forces of erosion are water, wind, glaciers, and gravity.
