Using the principle of Uniformitarianism, what can you infer about sandstone found on a beach?
What will be an ideal response?
Answer: The grains in the stone resemble the loose grains of quartz (sand) that cover the beach. So, it makes sense that these grains were formed in the same manner as the sand (processes of weathering) but then cemented together somehow. When closer examining the stone, a white film is seen between the grains, as if it was holding the grains together. It resembles calcite, and to test this idea, dilute acid is applied to the rock and the film fizzes and dissolves, suggesting it is in fact calcite.
