What are the three different types of rocks mentioned?

• Igneous, Metamorphic, Sedimentary

• Granite, Marble, Slate

• Quartz, Feldspar, Mica

• Sandstone, Clay, Gravel

Which process involves large rocks breaking up into small pieces called sediment?

• Cementation

• Erosion

• Compaction

• Weathering

What is biological weathering?

• Weathering by water

• Weathering by chemical reactions

• Weathering by temperature changes

• Weathering by living organisms

What causes chemical weathering?

• Wind erosion

• Acidic rain

• Plant roots

• Ice formation

Which example is a type of physical weathering?

• Hydrolysis

• Root wedging

• Oxidation

• Freeze-thaw

What is the process called when sediments are moved from one place to another?

• Sedimentation

• Erosion

• Transportation

• Deposition

What happens during the compaction stage in forming sedimentary rocks?

• Sediments are moved by wind

• Sediments are broken down

• Sediments are squashed together

What is cementation in the context of sedimentary rock formation?

• The initial formation of sediments

• The layers of sediments sticking together

• The movement of sediments by water

• The process of breaking rocks into smaller pieces

Which rock is an example of sedimentary rock?

• Marble

• Limestone

• Granite

• Quartzite

Why do sedimentary rocks often contain fossils?

• Because they are formed from molten material

• Because they are the hardest type of rocks

• Because dead organisms settle among the layers

• Because they are formed under high pressure
