Wind and water carry sand, debris, and small pieces of rocks and deposit them in layers. These layers pile up and after many years form a single rock called Rock A. The movement of tectonic plates buries Rock A deep inside Earth. Heat and pressure change the mineral composition of Rock A and transform it into Rock B. Rock B comes out to the surface of Earth due to plate movements. Which statement is most likely correct? Rock B may have fossils. Rock A may have gas bubbles. Rock B may have flattened crystals. Rock A may have shiny, glassy surface.
