Drawing the Rock Cycle

The video begins with an introduction to adventure and bicycles, explaining the etymology of 'bicycle'. It transitions into a discussion about Earth's layers, including the core, mantle, and crust, and the role of tectonic plates in forming mountains, earthquakes, and volcanoes. The rock cycle is then explored, detailing how igneous, sedimentary, and metamorphic rocks form and transform over time through processes like weathering, erosion, and subduction. The video concludes by emphasizing the geological timeline and the continuous transformation of rocks.

What happens when two tectonic plates collide?

• A river is formed.

• An ocean is formed.

• A mountain is formed.

• A desert is formed.

How do igneous rocks form?

• From the cooling and hardening of magma.

• From the compression of sediments.

• From the melting of ice.

• From the evaporation of water.

What natural process is responsible for the formation of the Grand Canyon?

• Erosion by the Colorado River

• Volcanic eruptions

• Tectonic plate collision

• Earthquakes

What causes sedimentary rocks to transform into metamorphic rocks?

• High heat and pressure

• Contact with water

• Freezing temperatures

• Exposure to sunlight

What is the final stage in the rock cycle that completes the transformation back to igneous rock?

• Melting in the mantle

• Freezing

• Weathering

• Erosion
