Exploring the Rock Cycle Dynamics

The video explains the rock cycle, highlighting how igneous, sedimentary, and metamorphic rocks transform through processes like weathering, erosion, heat, and pressure. It uses granite as an example to illustrate these transformations, showing how it can become sedimentary sandstone or metamorphic gneiss. The cycle is dynamic, allowing any rock type to change into another over time.

What does the rock cycle diagram show?

• The different types of rocks and how they change over time

• The different layers of the Earth

• The different types of minerals

• The different types of fossils

What type of rock is granite?

• Sedimentary

• Metamorphic

• Igneous

• Fossil

Tags

NGSS.MS-ESS2-1

What process forms igneous rocks?

• Weathering and erosion

• Compaction and cementation

• Solidification of magma or lava

• Metamorphosis

What happens to granite when it is exposed to weathering and erosion?

• It breaks down into small pieces called sediments

• It melts into magma

• It turns into a metamorphic rock

• It remains unchanged

What type of rock is formed when sediments are compacted and cemented together?

• Fossil

• Sedimentary

• Metamorphic

• Igneous

What can cause an igneous rock to transform into a metamorphic rock?

• Cooling quickly

• Intense heat and pressure

• Compaction and cementation

• Weathering and erosion

What happens to an igneous rock when it is exposed to intense heat and melts?

• It remains unchanged

• It returns to a liquid state of magma

• It turns into a metamorphic rock

• It turns into a sedimentary rock

What is the key idea behind the rock cycle?

• Rocks cannot change once they are formed

• Rocks can transform into any other type of rock

• Rocks can only transform into sedimentary rocks

• Rocks can only transform into one other type of rock

How do sedimentary rocks form?

• From the solidification of magma

• From the compaction and cementation of sediments

• From intense heat and pressure

• From melting into magma

What can happen to any type of rock in the rock cycle?

• It can transform into any other type of rock

• It can only become an igneous rock

• It can only become a sedimentary rock

• It cannot change
