Understanding Rocks and the Rock Cycle

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

• Sedimentary, Metamorphic, Volcanic

• Igneous, Volcanic, Sedimentary

• Igneous, Sedimentary, Metamorphic

• Metamorphic, Igneous, Volcanic

How are intrusive igneous rocks formed?

• By the accumulation of sediments

• By slow cooling of magma beneath the Earth's surface

• By rapid cooling of lava on the Earth's surface

• By the transformation of existing rocks under pressure

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

• Basalt

• Slate

• Granite

• Marble

What is the primary process involved in the formation of sedimentary rocks?

• Cooling of magma

• Recrystallization of minerals

• Compaction and cementation of sediments

• Melting of rocks

Which sedimentary rock is formed from the compression of seashells and marine skeletons?

• Conglomerate

• Limestone

• Shale

• Sandstone

What does the term 'metamorph' mean in the context of metamorphic rocks?

• To solidify

• To change form

• To erode

• To melt

Which rock is formed when limestone is subjected to intense heat and pressure?

• Basalt

• Slate

• Quartzite

• Marble

What initiates the rock cycle?

• Metamorphism

• Erosion of rocks

• Crystallization of magma

• Sedimentation

In the rock cycle, what can sedimentary rocks transform into under heat and pressure?

• Magma

• Metamorphic rocks

• Igneous rocks

• Sediments

Which process can transform metamorphic rocks back into magma?

• Erosion

• Cementation

• Melting

• Compaction
