| Question |
Answer |
| differential erosion |
occurs where a mountain or a plateau is made of both soft, weak rocks, and harder more resistant rocks; the weaker rocks wear away faster, leaving behind knobs and cliffs of more resistant rocks |
| formation |
rock layer composed of more than one kind of rock; the kinds and sequences of the rock can be recognized from one place to another |
| elevation |
vertical distance measure above sea level |
| rock column |
sequence of rocks |
| plateau |
large, nearly level area of land that is lifted or elevated above the surrounding area |
| limestone |
mostly smooth rocks, with fine-grain texture that contain calcite (and react to hydrochloric acid by fizzing to release carbon dioxide) |
| sandstone |
rocks with sandy, rough texture that do NOT react to hydrochloric acid |
| correlation (correlate) |
the relationship or connection between rock layers from two or more locations (rocks that are connected or RELATE) |
| calcite |
mineral compased of calcium, carbon and oxygen; this is the material in rocks that reacts to acid |
| shale |
smooth-textured rock that contains fossils |
| sample |
small, representative pieces |
| layers |
flat deposits of rock that can be thick or thin and extend over a large area |
