WHERE ARE SEDIMENTARY ROCKS FORMED?
This figure shows that heavy and/or large particles, moved by a river to the ocean, drop out first to the ocean bottom. The smaller the particles the longer it takes to settle out of the water. Sedimentary rocks form when particles (broken down rocks) are cemented together by minerals like calcite or quartz. Place a number on the diagram where you would find these sedimentary rocks:
2. CLAYSTONE3. SANDSTONE
4. CONGLOMERATE (hint: cemented together gravel)
