The video tutorial explains the rock cycle, highlighting how rocks transform over time. It begins with an introduction to the concept of rock changes, likening them to caterpillars becoming butterflies. The tutorial then delves into the formation of igneous rocks from magma and lava, followed by the creation of sedimentary rocks through sediment accumulation and pressure. Finally, it covers the formation of metamorphic rocks through heat and pressure, emphasizing the continuous and dynamic nature of the rock cycle.

What is the main reason why rock changes are difficult to observe?

• Rocks do not change at all

• Rocks are hidden underground

• Rocks change over long periods of time

• Rocks are too small to see

What is magma called when it reaches the Earth's surface?

• Metamorphic rock

• Sediment

• Igneous rock

• Lava

What type of rock is formed when magma cools down?

• Igneous

• Metamorphic

• Lava

• Sedimentary

What natural forces act like jackhammers to break down rocks into sediments?

• Plants and animals

• Earthquakes and volcanoes

• Water and wind

• Heat and pressure

• Turn them into magma

• Carry them into layers

• Melt them

What is the process called when sediments are pressed and cemented together over time?

• Erosion

• Sedimentation

• Metamorphism

What happens to rocks when they are exposed to heat and pressure but not melted?

• They turn into magma

• They become metamorphic rocks

• They become sedimentary rocks
