Only a small number of earth's minerals are commonly found in rocks what does this fact indicate?
3)rocks have a number of minerals in common
What do most igneous sedimentary and metamorphic rock have in common?
It is more likely that igneous and metamorphic, or igneous and sedimentary rocks would have something in common than sedimentary and metamorphic. The reason is because the processes involved in making metamorphic rocks is completely different than the processes needed to make sedimentary rocks. Only high temperature, high pressure minerals such as olivine, pyroxene, amphibole can withstand these kinds of conditions. Take quartz and feldspar, two of the most abundant minerals found in sedimentary rocks, these minerals would not be found in abundance in metamorphic rocks because they are not high temperature, high pressure rocks. But the most simple answer is that all the major groups of rocks are made of minerals. Metamorphic has high pressure and Igneous does to and both made from a particle called magma.
Does gabbro have a streak?
Only minerals have a streak, not rocks. The constituent minerals of a gabbro will all have a streak.
Give two examples of how a rocks color provides clues to the rocks mineral composition?
This is out of "Prentice Hall Science Explorer"MINERAL COMPOSITION AND COLOR"Rocks are made of mixtures of minerals and other materials. Some rocks contain only a single mineral. Others can contain several minerals. These minerals are known as rock-forming minerals.A rock's color provides clues to the rock's mineral comp. For example, granite is generally a light-colored rock that has high silica content. Basalt, is a dark colored rock that is low in silica. But as with minerals, color alone does not provide enough information to identify a rock.Geologists observe the shape and color of crystals in a rock to identify the minerals that the rock contains. In identifying rocks, geologists also use some of the tests that are used to identify mineral's. For example, testing the surface of a rock with acid determines whether the rock includes minerals made of compounds called carbonates."
What rocks don't contain minerals?
most rocks from what i know contain minerals especially sedimentary rocks. and don't all rocks eventually become sedimentary rocks so really don't they all contain minerals to some extent :) hope it helped (by the way i am only a gcse student)

What are the most common rocks and minerals found in Rhode Island?
I only know the minerals... They are quartz and pyrite and etc.
Are minerals rocks?
No, rocks are at least two kinds of minerals.
How are rocks and minerals are related?
Rocks and minerals are only related of that multiple minerals form rocks. Other than that, they aren't related at all.rocks are made of mineralsAll rocks are made of minerals!!!!!Rocks are composed of one or more minerals.
Why is metamorphic rock hard?
because a metamorphic rock is made up of different rocks.
What is the most common group of minerals and What is the percentage of the crust do they make up?
though there are thousands of different minerals only about 30 are common in earths crust. these 30 minerals make up most rocks in thee crust. i hope that helped :)
Are igneous rocks made up of only one mineral?
No, igneous rocks are not made up of only one mineral. They are typically composed of a variety of minerals, which are formed by the cooling and solidification of molten rock material. Some common minerals found in igneous rocks include quartz, feldspar, and mica.
Are minerals made only of rocks?
Yea
Does wool contain minerals?
no only rocks do!
What made rocks?
Rocks which are made of minerals can be made up of many minerals and they can also be made up of only one mineral. Generally rocks are made of two or more minerals
What rocks made of?
Rocks which are made of minerals can be made up of many minerals and they can also be made up of only one mineral. Generally rocks are made of two or more minerals
Why all rocks are made up of minerals but minerals are not made of rocks?
Well the rocks you find here on the surface are made up of many kinds of minerals, like when you see a certain type of rack that has small glass-like spots. Minerals are just mineral alone. A lump of lead is just only made up of lead, not anything else. Some minerals can be called rocks. Water is a mineral, but it is not a rock.
