What is a rock cycle?
Question asked by: knowitall
Most things in the natural world seem to go through cycles, of greater or lesser length and of various degrees of dramatic nature!
The rock cycle is the cycle for rocks.
Basically, rocks are formed, then they may be decomposed, then they may form again.
Rocks could form like sedimentary rocks, laid down on the ocean bed over years and years and pressure.
Then they live a quiet life for a while...
Then they might get sucked under and caught up in plate activity and be re-heated and pressurised to form metamorphic rocks.
Thus this is the rock cycle: the formation and destruction of rocks on a continual basis.
