What is the main source of heat that drives the movement of matter inside the Earth?

The middle part of the Earth, which is very hot.

In the demonstration, what materials were used to represent the Earth's crust and the matter beneath it?

Chocolate powder represented the crust, and milk represented the matter beneath the crust.

Tectonic plates are the broken pieces of the Earth's crust that move due to the movement of matter underneath.

As the heated matter rises, it cools off and then sinks back down.

Earthquakes, volcanoes, and the formation of new mountains.

Plate Tectonics - Heat Moves Matter

3 key concepts

1
Heat moves matter in the Earth, just like in a lava lamp, causing hot material to rise, cool, and then sink.
2
The Earth's crust is broken into pieces called plates, and these plates move due to the movement of matter beneath them.
3
The movement of the Earth's crust, called plate tectonics, causes events like earthquakes, volcanoes, and the formation of new mountains.
