a?

Answer 10

i would say so.. because there are three main types of rocks:
sedimentary, igneous and metamorphic.
So igneous will not be found in sedimentary rocks..

Answer 11

Fossils, igneous rock, and minerals can all be found in sedimentary rock. It's a collection of sand and other small minerals. Fossils almost exclusively form in sedimentary rock. And you could find igneous rock in sedimentary rock. You could also find metamorphic rock in sedimentary rock.

Answer 12

Igneous and metamorphic rock breaks down to form sedimentary rock.

Answer 13

Answer 15

First off, fossils are not a rock. So it can't be A or D. Second off igneous rock is hardened lava. It's not made from minerals. Sedimentary rock is made by minerals layering over each and compacting.

No, fossils aren't a rock.
But sedimentary rock CONTAINS fossils
CONTAINS

Sedimentary rocks do not oftenly contain fossils. And igneous rocks definitely do not do it has to be minerals.

Answer 20

Um, what do you think silicon is? And nickel? Where does it come from? Maybe, hmm, the earth's mantle? Fossils, like I said before, are found almost exclusively in sedimentary rock.

Answer 21

But compared to minerals? Minerals would be found 99% compared to the 1% of fossils you find

ROFL:

"is it b?"
"do you know what a igneous rock is?"
"is it b?"

Answer 23

It is all of the above. Minerals are in ALL rocks. In fact, that is part of the definition of rock: "the solid mineral material forming part of the surface of the earth and other similar planets, exposed on the surface or underlying the soil or oceans."

Here is a bit on fossils in sedimentary rock (shale): "Fossils, animal tracks/burrows and even raindrop impact craters are sometimes preserved on shale bedding surfaces. Shales may also contain concretions consisting of pyrite, apatite, or various carbonate minerals."
