Metamorphic rocks are rocks which have been changed by heat an pressure. The deeper you go within the earth, the more heat and pressure there is, which is why metamorphic rocks form there.

What are foliated metamorphic rocks?
Foliated rocks have layers in them. We often refer to the layers as Banding.
What do butterfly's and metamorphic rock have in common?
They both undergo a complete change in appearance.Butterflies will normally start off life as a caterpillar, after eating their fill the pupate and undergo "metamorphasis", changing from a worm-like insect into a winged butterfly.In the same way metamorphic rock can be either sedimentary or ifneous in origin, normally it is then heated (or melted again) forming a new type of material. Example, sandstone (sedimentary rock) can be heated to melting point, once it hardens it has become a new type of metamorphic rock. Metamorphic rock often has intrusions of the original parent material in it, making for interesting samples.

Crude oil is often found in the Earths crust why is this a problem?
billions of gallons of oil and tons of coal has been extracted from the earths crust which is obviously leaving an emptyness behind, i find it hard it hard to believe that this space remains empty without any collapse in the crust to fill the empty space. if there was a collapse in the earths crust then it would surely be felt as an earthquake or maybe even a tsunami.Earth is only a few kilometers thickness but crude oil pockets could lie anywhere, even under the sea.The crust has to be bored and plugged up for extraction which causes spillage and harms bio life to upset the ecology.
Why do metamorphic rocks often form deep under the surface of the earth?
Metamorphic rocks are often found deep under the earth's surface because metamorphic rocks form from heat and pressure. Therefore, they form while they are under the earth's surface.
Gneiss is formed from what rock?
Gneiss is a metamorphic rock. It is formed form another metamorphic rock called schist (sh-ist). Schist is formed form fine grained sedimentary rock (often shale). While gneiss is formed by great pressure from moving plates of the earth's crust.
How does tension change the shape of earths crust?
by pulling it making it thinner in the middle
