This hard, round mass of sedimentary rock cement is carried into place by ground water.

Sedimentary Rock Formation

Sedimentary rock formation begins with igneous, metamorphic, or other sedimentary rocks. When these rocks are exposed at the earth's surface they begin the long slow but relentless process of becoming sedimentary rock. Weathering All rocks are subject to weathering. Weathering is anything that breaks the rocks into smaller pieces or sediments.

7.4 Regional Metamorphism – Physical Geology

7.4 Regional Metamorphism. As described above, regional metamorphism occurs when rocks are buried deep in the crust. This is commonly associated with convergent plate boundaries and the formation of mountain ranges. Because burial to 10 km to 20 km is required, the areas affected tend to be large. Rather than focusing on metamorphic rock

Metamorphic rocks. Metamorphic rocks are named for the process of metamorphism, or change, that affects rocks.The changes that form metamorphic rocks usually include increases in the temperature (generally to at least 392F [200C]) and the pressure of a precursor rock, which can be igneous, sedimentary, or metamorphic, to a degree that the minerals in the rock are no longer stable.
