What kind of sedimentary rock is formed from compacted sand?

• marble

• limestone

• sandstone

• conglomerate

The image shows a forest in a bog, a type of wetland. What process best explains how the trees in the forest might form fossil fuels?

• the trees produce carbon dioxide that is released to the atmosphere

• a forest fire converts all the trees to ash, which forms fossils

• the dead trees fall to the forest floor and are buried by sediment for millions of years

• the dead trees fall to the forest floor and are broken down by decomposers

Gary is making a list of the processes in the formation of shale, a type of sedimentary rock. Gary looks at step 1 and thinks about where the sediment that was deposited came from. How is this sediment formed?

• by plant and animal fossils turning into rocks

• by plant and animal fossils getting buried for millions of years

• by rocks melting down because of elements like heat and pressure

• by rocks breaking down because of elements like wind and rain
