Carefully read the the table below about specific rocks and their formation and characteristics. Out of the options, which rock(s) would be considered sedimentary?
Rock Formation Characteristics
Basalt Crystallization of magma on Earth's surface Dark-colored, fine-grained, often appears porous
Coal Deposition of material, including organic remains, that cement together over time Blackish or brownish color, combustible solid
Granite Crystallization of magma at depths under Earth's surface Multicolored, granular with large grains
Gneiss Exposure of materials to high heat and pressure Has alternating dark and light bands that appear in layers
Limestone Deposition of material, including organic remains, that cement together over time Lighter in color, contains fragmented skeletal remains of marine organisms
Slate Exposure of materials to high heat and pressure Multicolored, fine-grained, and layered
