Description

Rock Cycle

How Rocks Change

Processes That Cause Change it can take thousands of years for a rock to weather and erode it can take many more for eroded pieces to change into sedimentary rock high heat and pressure change rocks sometimes rocks can melt completely when it cools and hardens it has turned from metamorphic to igneous

high heat and pressure change rocks

sometimes rocks can melt completely

when it cools and hardens it has turned from metamorphic to igneous

a rock can be changed many times some part of the first rock will still be there after each change

The Rock Cycle rock cycle: the never-ending rock changes the rock cycle has many different paths as rocks move through the rock cycle the materials that make them up are used over and over

Summary rocks change from one kind of of rock to another in the rock cycle some of the processes in the rock cycle are: weathering, erosion, melting, compaction, and cementation
