1. The sedimentary rock known as conglomerate typically forms in environments in which particles can become rounded, such as fast-flowing rivers. 2. An example of is when moving water slows down and particles being transported in the water begin to settle out (sediment) in a new location. 3. is a type of sediment that feels smooth to your fingers but gritty in your mouth. 4. The most common chemical sedimentary rock is . 5. Limestone typically doesn't accumulate in the ocean at depths below 4,000 meters because below that depth, calcite is . 6. Based on the principle of original horizontality, geologists conclude that layers of sedimentary rock that have been tilted must have been subjected to . 7. Based on the principle of inclusions, the cobbles in conglomerate must have been formed the conglomerate. 8. Geologists use the principle of to justify using fossils in a sample of sedimentary rock to determine the rock’s age. 9. Partings between adjacent beds of sedimentary rock may represent periods of , which could range from a few decades to a few centuries. 10. Some graded beds, especially those resulting from deposition by a fast-moving debris flow, are reversed, which means material is at the top instead of at the bottom.
