The Rock Cycle

Professor Dave explains the rock cycle, detailing how igneous, sedimentary, and metamorphic rocks transform through geological processes. The cycle involves the formation and destruction of rocks, with examples from Earth's history. Ancient rocks like the Jack Hills Conglomerate contain minerals over 4.4 billion years old. The video also introduces weathering and erosion, setting the stage for further exploration of these processes.

What are the three main types of rocks discussed in the introduction?

• Igneous, Sedimentary, Metamorphic

• Igneous, Volcanic, Metamorphic

• Sedimentary, Volcanic, Igneous

• Metamorphic, Volcanic, Sedimentary

Which process is responsible for the transformation of igneous rocks into sedimentary rocks?

• Metamorphism

• Subduction and uplift

• Weathering and erosion

• Melting and cooling

What geological process involves the return of rocks to the mantle?

• Lithification
