The video tutorial explains the Earth's crust and the theory of plate tectonics, detailing the three types of plate boundaries: convergent, divergent, and transform. It uses a model with graham crackers and icing to demonstrate these boundaries and their effects, such as the formation of new rock and volcanoes. The tutorial also simulates continental formation using cream and cocoa, illustrating how heat and pressure cause the crust to expand and crack, forming new geological features.

• 100 to 150 kilometers
