A good word to describe most of them would be recycled, by nature, via the rock cycle.

Why are rocks so boring?
Rocks are nature, and nature is apart of who you are as a person.
What types of rocks contain fossils?
Igneous rocks and most metamorphic rocks, of an igneous origin.
Which force does not break down rocks in nature?
sunlight does not break down rocks
Where might you see a similar type of weathering in nature?
rocks
Why can't we find rocks from the Hadean period?
Earth's temperature was too high for solid rocks to form.
The first fossils of land plants and animals are found in rocks from the?
Cambrian Period Actually the correct answer to this question is the "Pennsylvanian Period".
What time period are most rocks from in glacier national park?
Most of the rock is pre-Cambrian rock.
From what time period are most of rocks in Glacier National Park?
Most of the rock is pre-Cambrian rock.
Why were there no plants during the Cambrian time era?
There were simple plants in the Cambrian Period(542 - 488.3Ma). Fossil algae has been found in Cambrian Rocks. Evidence of primitive algae from the Precambrian Super-Eon has also been found but exact classification has not been established. It is true that embryophytes (Plants we most recognise) did not evolve until the Ordovician Period(488.3 - 443.7Ma).
What is ediacaran?
Ediacaran fauna are the fossil animals found in rocks dated around 650-540 million years ago, just before the Cambrian period.
Why haven't paleontologists found any rock from the earliest years of Earth's existence?
All rocks were molten in that period of time. **Possible improvement All rocks from before the Cambrian Period have been melted and recrystallised, as far as is known. (Though I don't fancy testing the age of every single rock on earth - do you) In the same way there are no Pre-Cambrian fossils. We have not tested every single fragment on earth, so all evidence is destroyed.
What hexactinellida can be found in the Cambrian?
Fossil evidence for the Hexactinellid class of sponge actually predates the Cambrian Period. Fossils of the genus Paleophragmodictya is the oldest fossil sponge currently known and was found in rocks dating back to the Ediacaran Period of the Neoproterozoic Era.It is thought that the Extinction events that occured in the early Cambrian effected the early sponges greatly but diversification of Haexactinellida after this brought many new forms. A species of Konyrium has been found in late Cambrian rocks.Many species were to evolve though out the Paleozoic and Mesozoic Era although hexactinellida would not see maximum diversity until the Cretaceous Period.
Did birds first begin to fly in the pre-Cambrian period?
No. Birds are air breathing vertebrates, there were no air breathing animals in the Precambrian. The earliest bird fossils are found in rocks about 160 million years old in the Jurassic period.

What is meant by term Cambrian explosion?
The Cambrian explosion is an apparently sudden increase in fossils marking the separation between Precambrian rocks and Cambrian rocks. At one time this was believed to mark the beginning of multicellular life, but in fact it only marks the evolution of hard body parts (most of which were made of calcium carbonate). It turns out that there were as many multicellular organisms in the late Precambrian as there were during the Cambrian explosion at the beginning of the Cambrian, but the lack of hard body parts in those organisms made the formation of easy to identify fossils of those organisms much rarer.
