Rock Types and Their Transformations in the Earth's Cycle

The video tutorial introduces the types of rocks: igneous, sedimentary, and metamorphic. It explains how each type forms, with igneous rocks originating from cooled magma or lava, sedimentary rocks forming from compacted sediment, and metamorphic rocks resulting from heat and pressure on existing rocks. The rock cycle is described as the process of transformation between these types. The tutorial concludes with a summary and encourages viewer interaction.

What are the three main types of rocks?

• Sedimentary, Volcanic, Crystalline

• Metamorphic, Crystalline, Igneous

• Igneous, Volcanic, Metamorphic

• Igneous, Sedimentary, Metamorphic

What is the name of the rock formed when lava cools?

• Limestone

• Granite

• Sandstone

• Basalt

Which type of rock is granite?

• Sedimentary

• Volcanic

• Metamorphic

• Igneous

How are sedimentary rocks formed?

• By crystallization of minerals

• By melting of other rocks

• By compression of sediment

• By cooling of lava

Which of the following is an example of a sedimentary rock?

• Sandstone

• Marble

• Slate

• Granite

What causes metamorphic rocks to form?

• Cooling of magma

• Heat and pressure

• Sediment deposition

• Erosion by water

Which rock changes into marble under heat and pressure?

• Granite

• Limestone

• Basalt

• Sandstone

What is the rock cycle?

• The deposition of sediment

• The cooling of magma into rock

• The transformation of rocks from one type to another

• The process of rock erosion

What happens to sedimentary rock under high heat and pressure?

• It metamorphoses into metamorphic rock

• It becomes igneous rock

• It erodes into sediment

• It melts into magma

Which process is NOT part of the rock cycle?

• Rock erosion

• Magma cooling

• Sediment compaction

• Photosynthesis
