Rocks and Their Formation

What are the three main types of rocks?

• Sedimentary, Metamorphic, Igneous

• Magma, Lava, Sediment

• Granite, Basalt, Limestone

• Sandstone, Mudstone, Coal

How is sedimentary rock formed?

• By volcanic eruptions

• By cooling of molten rock

• By layers of rocks and dirt being squeezed together

• By chemical changes due to heat

What is magma?

• Molten rock underground

• A type of sedimentary rock

• Molten rock above ground

• Solidified lava

Which of the following is an example of sedimentary rock?

• Sandstone

• Basalt

• Granite

• Marble

What causes metamorphic rocks to form?

• Cooling of lava

• Pressure and heat from magma

• Erosion by wind and rain

• Deposition of sediments

What is the rock cycle?

• The mining of coal

• The layering of sediments

• The continuous transformation of rock types

• The process of rocks melting and cooling
