Why are metamorphic rocks very hard and resistant to wear?
quartzite is made from quartz. in the case of metamorphic rocks, quartzite is made from regional metamorphism. in the process of regional metamorphism, pressure is applied making the rock hard and dense.
What is the shape of an metamorphic rocks?
The shape of metamorphic rocks can vary widely depending on the specific rock and the conditions under which it formed. Some metamorphic rocks, such as slate or schist, may have layered or foliated textures. Others, like marble or quartzite, are typically more massive and may have a granular or compact appearance.
Would you expect a quartzite or a sandstone to break more easily?
a sandstone would break more easily because a quartzite is harder. a quartzite is made of sandstone melted together by magma
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 the difference between foliated and non-foliated rock textures?
In subject of metamorphic rocks, to be foliated is to have their grains arranged in parallel layers or bands. Non foliated is when the rocks' grains are made randomly in no arranged pattern.Reference:Prentice Hall Earth Science 2009
What does the metamorphic rock quartzite turn into because of pressure and heat?
The next step would probably be melt.
What does sandstone change to?
That depends on what happens to it. If it is sufficiently heated and compressed it will metamorphose to quartzite.
What is a kind of non foliated metamorphic rock?
Metamorphic rocks are rocks that have their grains arranged in parallel layers or bands. Foliated rocks are formed under great pressure and heat, and when they cool they have a banded grain pattern.

Why is quartzite very hard and more resistent than its parent rock?
Quartzite is a nonfoliated metamorphic rock that formed by the metamorphism of pure quartz sandstone. The intense heat and pressure of metamorphism causes the quartz grains to compact and become tightly intergrown with each other, resulting in very hard and dense quartzite. I found this on Minerals Education Coalition
How is a metamorphic rock formed'?
Non-foliated metamorphic rocks such as quartzite and marble do not display the banding or layering that are present in foliated rocks. This is because their parent rock was usually sedimentary and more pure in mineral composition than the parent rocks of foliated rocks. The metamorphic rock forms from conditions of high heat and/or pressure from depth of burial.

Why is quartzite used for tiles?
Because they are smooth
Why is quartzite banded?
because it is so get over it.
