The video explains the rock cycle, detailing how igneous, sedimentary, and metamorphic rocks form and transform. It covers the processes of weathering, erosion, and the effects of heat and pressure. The cycle is continuous, with rocks changing forms over time. The video also highlights the Grand Canyon as an example of erosion and sedimentary rock formation. Viewers are encouraged to engage with additional learning resources.

Which process involves the breaking down of rocks due to weather elements?

• Compaction

• Weathering

• Melting

What are the examples of sedimentary rocks?

• Sandstone, Limestone, Shale

• Granite, Obsidian, Basalt

• Slate, Marble, Quartzite

• Diamond, Ruby, Sapphire

Which rock type is formed by the compaction and cementation of sediments?

• Metamorphic rock

• Granite

• Igneous rock

• Sedimentary rock

What is the role of heat in the formation of metamorphic rocks?

• It melts the rocks completely

• It breaks the rocks into sediments

• It has no role

• It changes the minerals without melting the rocks

How are metamorphic rocks formed?

• Erosion of mountains

• Cooling of magma

• Compaction of sediments

• Heat and pressure altering existing rocks

Which rocks can metamorphic rocks transform into in the rock cycle?

• None, they do not change

• Igneous or sedimentary

• Only igneous

• Only sedimentary

What happens to rocks in the rock cycle?

• They turn into magma only

• They disappear over time

• They can transform between igneous, sedimentary, and metamorphic

• They only form once and do not change
