What more should you know about the placement of rock material?
10. Marble most likely would be found in a location where there is contact metamorphism since marble is a metamorphic rock formed from the metamorphism of limestone under heat and pressure.
11. A felsic igneous rock most likely would be found at a location where you might expect to see lighter-colored minerals and possibly granite, which is a common felsic rock.
12. A rock that would fizz upon contact with dilute hydrochloric acid is typically a limestone, which is composed mainly of calcite (calcium carbonate) that reacts with the acid to release carbon dioxide gas.
13. Fossil corals and clams found in Devonian age limestones of western New York State would most likely lead to the inference that this region was once covered by water, as corals and clams are marine organisms and their presence in the rock record indicates the past presence of a marine environment.
14. The size of the crystals present in a rock is primarily a result of the time necessary for the rock material to cool and solidify. Larger crystals usually indicate slower cooling, which allows more time for crystals to grow.
14. Bedrock most likely to contain fossils would be sedimentary layers, as sedimentary rocks are formed from sediments that can include the remains of organisms, which may then become fossils.
