Sedimentary Rock Formation Concepts

Where are most sedimentary rocks found?

• Deep underground

• At Earth's surface

• Near volcanic activity

• Inside metamorphic rock formations

What is the process called when tiny pieces of rock break off?

• Erosion

• Deposition

• Weathering

• Compaction

Which of these natural elements can cause rocks to break apart through weathering?

• Moving water and temperature changes

• Plant roots and animal digging

• Wind and gravity

• All of the above

What two processes work together to press and glue sediment into sedimentary rock?

• Erosion and deposition

• Weathering and cementation

• Compaction and cementation

• Deposition and weathering

What type of sedimentary rock is formed from the shells of sea creatures?

• Conglomerate

• Sandstone

• Shale

• Limestone

Fossils are most often formed when

• lava covers dead organisms

• dead organisms are able to dry out in the sun

• dead organisms are buried by sediment

• dead organisms are exposed to heat and pressure

Fossils help us

• learn about ancient plants

• learn about ancient animals

• learn about how Earth's environment has changed over time
