Mantle ConvectionHeat from the core and the mantle itself causes convection currents in the mantle.

Convection and the MantleHow does a Lava Lamp Model Convection Currents?

Rock OriginsRocks are classified by the way they formed.

Classifying Rocks

How Sedimentary Rock FormsSedimentary rocks form through a series of processes over millions of years.

Sedimentary Rocks

What is the proper sequence of the terms in the word bank that will show how mountains can change into sedimentary rock?

Sedimentary Rocks

The Rock CycleThrough melting, weathering and erosion, and heat and pressure, the rock cycle constantly changes rocks from one type into another type.
