Chemical – rock dissolved (in water) into individual molecules, especially effective if the water is acidic or hot Mechanical – rock is physically broken into smaller pieces, happens from impact, thermal explosion, or frost wedging 3) What are the four agents of erosion, and which is most important? Water (most important), wind, gravity, ice 4) Know the three ways of transporting (=eroding) weathered material in water.
