Which of the following statements best describes compaction AND cementation?

Select two correct answers.

• Compaction happens when layers of rock press together.

• Compaction happens when rocks are weathered and eroded.

• Cementation happens when minerals stick the rock sediments together.

• Cementation happens when water covers layers of rock.

What needs to be present in the peat for fossil fuels to form?

• Sand and small pieces of wood

• Mostly decaying plants

• Mostly lava and sedimentary rocks

• Mostly minerals

Answer explanation

peat. noun. ˈpēt. : a dark brown or blackish material that is the remains of plants partly decayed in water and is sometimes dug up and dried for use as fuel.

Peat is the science word for "dead organic matter" 👍

What process needs to occur over many years for sedimentary rocks to be completely formed?

• Evaporation and condensation from the water cycle

• Weathering of rock to break it apart

• Compaction and cementation to make sedimentary rock

• Heat and pressure to change the dead plants into coal

Fossil Fuels formed over long periods of time after particles in water settled to the sea floor and formed marine mud.  What kinds of particles needed to be present in the marine mud in order for fossil fuels to form.

• Mostly sand and a few small bits of wood

• Mostly decaying organisms

• Mostly lava and a few sedimentary rocks

• Mostly metal minerals

Some students made a model to show one of the first steps in the formation of sedimentary rock.  The students pour 2 cm of light-colored sand into a clear plastic box.  Then they add 1 cm of gravel.  Finally, they pour 2 cm of dark-colored sand on top of the gravel.  Which characteristic of sedimentary rock does this model best show?

• Sedimentary rock is made of layers.

• Sedimentary rock is cemented bits of rock.

• Sedimentary rock is often limestone.

• Sedimentary rock is common in Texas.

What characteristic of swamps is important to the formation of coal?

• High Temperature

• Abundant Plant Life

• Frequent Rains

• Reptile Predators

The formation of fossil fuels is a process that takes millions of years and starts with energy from the sun. The sun contributes to the formation of fossil fuels by - 

• heating up the Earth's core where fossil fuels form

• generating winds so humans use less fossil fuels

• give energy to the living things that become fossil fuels 

• giving off heat, similar to burning fossil fuels

How are Sedimentary Rocks formed?

• Cooling and Hardening

• Heat and Pressure

• Compacting and Cementing

• Melting
