Rock Types and Formation

Which type of rock is formed from cooled magma or lava?

• Sedimentary

• Metamorphic

• Igneous

• Fossilized

What does the term 'intrusive igneous rock' refer to?

• Rock formed from lava cooling on the surface

• Rock formed from magma cooling slowly underground

• Rock that contains fossils

• Rock formed from sediment layers

Which of the following is an example of extrusive igneous rock?

• Granite

• Obsidian

• Limestone

• Slate

How are sedimentary rocks primarily formed?

• By cooling of magma

• By the accumulation and compression of sediments

• By exposure to high heat and pressure

• By crystallization from molten rock

What type of material can be found in sedimentary rocks?

• Only inorganic minerals

• Fossils and organic material

• Only igneous fragments

• Pure magma

What is the primary process that leads to the formation of metamorphic rocks?

• Erosion

• Cooling

• Heat and pressure

• Sedimentation

In the rock cycle, what happens to sedimentary rocks that are pushed below the Earth's surface?

• They become igneous rocks

• They are eroded into sediment

• They transform into metamorphic rocks

• They melt into magma

Which of the following best describes the formation of granite?

• It is formed from volcanic activity on the surface.

• It is an intrusive igneous rock formed from slowly cooled magma.

• It is a sedimentary rock formed from compressed sediments.

• It is a metamorphic rock formed from limestone.

What is the main difference between intrusive and extrusive igneous rocks?

• Intrusive rocks are formed from sediments, while extrusive rocks are not.

• Intrusive rocks cool slowly underground, while extrusive rocks cool quickly on the surface.

• Intrusive rocks contain fossils, while extrusive rocks do not.

• There is no difference; they are the same.
