What are some Common rocks and minerals?
rocks: igneous rocks,metamorphic rocks,sedimentary rocks ect.................
Metamorphic rocks are classified into two groups?
The two main groups metamorphic rocks are classified are foliated rocks (meaning they have "bands"), and there are non-foliated rocks.
Contrast foliated and nonfoliated metamorphic rocks?
Foaliated rock can form in one or two ways. Extreme pressure may cause the mineral crystals in the rock to realign or regrow to form parallel bands. Foaliation also occurs as minerals that have different compositions separate to produce a series of alternation dark and light bands. Most nonfoliated metamorphic rocks share at least one or two main characteristics. First, the original rock that is metamorphosed may contain grains of only one mineral or contains very small amounts of other minerals.
What is 2 types of metamorphic rocks?
Metamorphic rocks are formed by the process of extreme heat, pressure and other chemicals. Two types of metamorphism are dynamic which makes the pressure and extreme heat and thermal which is caused by the heat of magma from a volcanic eruption.
What are two possible fates for a igneous rock?
Two of the most common fates of igneous rocks are to become sediment (and later sedimentary rocks) or to become metamorphic rocks.

What are the common kinds of metamorphic rocks?
The most common metermorphic rocks are : Marble, quartz, slate, phyllite, schist, geniss.
Is quartzite foliated or nonfoliated?
Quartz is a mineral, not a rock that neither does or does not exhibit foliation (a banding, layering, or alignment of minerals that presents itself in some metamorphic rocks). Quartzite, a rock made almost entirely of quartz, is a non-foliated metamorphic rock.

Metamorphic rocks are probably the most common rock type found in the Earth's crust?
false
What 2 things are metamorphic rocks formed from?
Heat and pressure are the most common cause of metamorphism of rock.

Two of the most common fates of igneous rocks are to become sediment (and later sedimentary rocks) or to become metamorphic rocks.
What do most igneous sedimentary metamorphic rocks 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.

What describes the thin flat layering in most metamorphic rocks?
The thin flat layering found in most metamorphic rocks is called foliation
