5 True/False Questions

1. sediments = clastics = detritus → particles of other rocks that have been eroded from one place, transported to another, and deposited there

   True        False

2. nonrenewable → CAN BE USED UP

   True        False

3. biochemical non-clastic sedimentary rocks → A. biochemical depositions of calcite by organisms that take in sea water through life processes and extract the calcium carbonate thus secreting it as an exoskeleton, their shells are either compacted or lithified(cemented together) creating chalk, coral, copuina. B. COAL- compaction of plant materials from freshwater swamp (stages: peat-lignite-bituminous coal-anthracite coalmetamorphic)

   True        False

4. ripple marks → asymmetrical ripples are formed by WIND AND WATER that form in sands, symmetrical ripples are formed by WATER ONLY in sands produced by back and forth motion of water

   True        False

5. agents of weathering → water, wind, ice, and gravity

   True        False
