Want this question answered?
Rocks change through the processes that take place within the rock cycle.
That would be a fossil.
Continental rocks are older than oceanic rocks. The continents have been continously growing over millions of years and adding the oceanic sediment to their margins over time.
i think its the rock cycle im not sure hope this helps ......i guess 2012 :)
It all depends on where the sand is sourced from, as sand is simply crushed rocks weathered down over millions of years. It is used in the manufacture of glass and silicon.
Erosion and weathering over millions of years

Rocks get eaten away by weathering and erosion
forms from dead plants and animals that compress deep in the Earth's crust over millions of years.

FOSSILS are found in sedimentary rocks. sedimentary because the rocks have been under water for over millions years and build layers till it made a cliff. THIS IS ROCK CYCLE
they are found in layers because over the millions of years they have formed over the top of each other and eventually formed a rock

The beach is a result of millions of years of erosion by the sea. Millions of years ago rocks were in the place of the sand, but the ocean over time broke away little pieces. Eventually all the rocks were gone, and sand stayed in their place. This is why beaches/shores only occur near water.
The changing of rocks over time is called the rock cycle. It involves processes such as weathering, erosion, deposition, compaction, and cementation that transform rocks from one type to another. This cycle is driven by geological forces and occurs over millions of years.
