edgar, I'm no geologist or scientist, but I question the conclusions made about those rocks. Layering is not strictly limited to water, IMHO. WHAT IS THE ORDER OF THE LAYERS OF ROCKS?
There is actually no specific answer to this as rocks change over time. What we do know is that the bottom layer of rocks in the oldest, and the layers of rock get younger as they pile on top of each other.
WHAT IS THE ROCK CYCLE?
Rocks are always changing in what is called the rock cycle. It takes millions of years for rocks to change.
Take a look at this example of the rock cycle and how rocks can change from igneous to sedimentary and to metamorphic over time.
Melted rock or magma comes to the earth’s surface by the force of a volcano. It cools down and there you have igneous rock.Next the weather, a river or other events will slowly break up this rock into small pieces of sediment.When sediment builds up over time and hardens over years, now you have a sedimentary rock.Slowly this sedimentary rock gets covered with other rocks and end up deep in the Earth’s crust.When the pressure and heat get high enough, the sedimentary rock will change into a metamorphic rock and the cycle starts all over again.
That’s really interesting stuff!
One thing to remember is that not all rocks follow this cycle. They can go in any order at all.
