What are the three important words you need to keep in mind whenever you are thinking about geology?
heat, pressure, time
How are the layers different and the same?
same- They are all layers of the work.
different- The crust, mantle, and core are different because some parts are solid and some parts are liquid. The crust, mantle, and core are also different because some parts are hotter than others.
