Journey Through The Rock Cycle: From Magma To Metamorphosis

The video explains the rock cycle, highlighting the formation and transformation of igneous, sedimentary, and metamorphic rocks. It begins with igneous rocks formed from cooled magma or lava, using basalt as an example. The process of erosion and sediment transport by natural forces is described, leading to the formation of sedimentary rocks through accumulation and cementation. The video also covers metamorphic rocks, formed under heat and pressure, and the role of subduction zones in the rock cycle. The cycle concludes with the potential for rocks to melt and form new igneous rocks.

What are the three main types of rocks involved in the rock cycle?

• Metamorphic, igneous, and volcanic

• Sedimentary, metamorphic, and volcanic

• Igneous, volcanic, and sedimentary

• Igneous, sedimentary, and metamorphic

How does igneous rock form?

• By the transformation of existing rocks under pressure

• From the accumulation of sediments

• By the cooling and hardening of magma or lava

• Through the erosion of existing rocks

What natural processes can transport rocks?

• Gravity and magnetism

• Sunlight and rain

• Earthquakes and volcanoes

• Wind, water, and ice

What is a conglomerate rock?

• A rock formed from cooled lava

• A type of sedimentary rock with large rounded fragments

• A type of metamorphic rock with layered structure

• A rock formed from compacted clay

What role does cement play in the formation of sedimentary rocks?

• It melts the sediments together

• It fills spaces around sediments with minerals, binding them

• It erodes the sediments

• It cools the sediments into rock

What causes metamorphic rocks to form?

• Erosion by wind and water

• Cooling of magma

• Accumulation of sediments

• Temperature and pressure changes inside the Earth

Which rock can transform into marble under heat and pressure?

• Sandstone

• Limestone

• Granite

• Basalt

What is the parent rock of quartzite?

• Sandstone

• Limestone

• Granite

• Basalt

What happens to rocks at a subduction zone?

• They are eroded by water

• They are transported by wind

• They are compacted into sedimentary rocks

• They undergo metamorphism due to heat and pressure

What is the raw material for new igneous rocks?

• Sediments

• Magma

• Sand

• Clay
