The video tutorial explores the formation and characteristics of the three main types of rocks: igneous, sedimentary, and metamorphic. It begins with the creation of igneous rocks from magma, highlighting their ancient origins and ongoing formation. The process of sedimentary rock formation is explained through weathering, erosion, and lithification. Metamorphic rocks are discussed in terms of their transformation under heat and pressure. The video concludes with an overview of the rock cycle, illustrating how rocks can change from one type to another over time.

What does the term 'igneous' mean?

• Fire

• Water

• Earth

• Air

How is granite formed?

• Quickly on the Earth's surface

• Slowly underground over thousands of years

• By the accumulation of sediments

• Through biological weathering

What process turns sediments into stone?

• Weathering

• Erosion

• Metamorphosis

• Lithification

Which type of weathering involves plant roots?

• Thermal weathering

• Biological weathering

• Chemical weathering

• Mechanical weathering

What is the main characteristic of metamorphic rocks?

• They are formed from magma

• They are formed by the accumulation of sediments

• They are changed by heat and pressure

• They are formed by biological processes

What does limestone metamorphose into?

• Granite

• Obsidian

• Pumice

• Marble

What is the rock cycle?

• The process of forming metamorphic rocks

• The process through which rocks transform into different types

• The process of forming sedimentary rocks

• The process of forming igneous rocks

What happens to rocks when they are exposed to high enough heat?

• They turn into metamorphic rocks

• They turn into biological rocks

• They turn into sedimentary rocks

• They melt into magma

What can sedimentary rocks break down into through weathering?

• New biological rocks
