Sedimentary Rocks and Fossil Fuels

Karen and Timothy are making a table to list the steps in the formation of fossil fuels. They have completed a part of their table. What processes should replace the question marks in the table?

• step 1: growth of organisms; step 3: compaction and heating

• step 1: erosion and weathering; step 3: deposition and heating

• step 1: growth of organisms; step 3: deposition and cementation

• step 1: erosion and weathering; step 3: compaction and cementation

Where do fossil fuels come from?

• soil that has been turned into liquid by large amounts of pressure

• water mixed with rock below the surface

• a kind of large mushroom that is now extinct

• both plant and animal remains

The image shows sediments at the bottom of a lake. Over time, layers of sediment at the bottom of the lake can form sedimentary rock. What process best explains how the layers of sediment turn into sedimentary rock?

• the pressure of the water forces the layers of sediment together

• the cold temperature of the water freezes the layers of sediment

• the pressure of the water melts the layers of sediment

• the cold temperature of the water dissolves the layers of sediment

Limestone usually forms from tiny pieces of sea shells that collect and are buried on the ocean floor. What type of rock is limestone?

• sedimentary

• igneous

• volcanic

• metamorphic

What process at the surface of the Earth is part of the formation of sedimentary rocks?

• water deposited sediment in layers

• magma rising from the Earth's mantle

• rain falling into the ocean

• the cycle of day and night

The picture shows a rock formation in Arizona. Which of the rocks' characteristics best shows that the rocks formed in layers over time?

Mia is making a model of one kind of rock. She makes her model by layering crackers and peanut butter. What does Mia's model show about how rocks are formed?

• rocks are always brown in color

• rocks can never contain any air

• rocks can be formed in layers

• rocks can be made of two materials at most
