What can you infer about metamorphic rocks from their names?
That they have undergone some form of change. For more information on metamorphic rocks please see the related question.
Why do the other two main types of rocks not contain fossils?
Igneous rocks form directly from a melt, hence there are no fossils contained within them. Metamorphic rocks are pre-existing rocks (sedimentary, igneous, or even metamorphic rocks themselves) which have undergone significantly increased pressures and/or temperatures. Any structure(s) or fossils which may have been present tend to be destroyed, reworked, or have their character diminished. Additionally, the presence or absence of water can often cause a wide variation in the mineral assemblages.
The major forces that form folded mountains are?
Compressional Stresses
What rocks form as melted rocks?
igneous
Which rocks are commonly non foliated?
Some common non foliated rocks include sandstone and limestone. The majority of rocks are non-foliated as foliation is a rock texture caused most commonly by the recrystallisation of rocks that have undergone metamorphism. However it can also occur in igneous rocks due to the alignment of crystals during crystallisation and the formation of cumulates in a magma chamber or due to frictional drag forces between a magma and the magma chamber walls and also form in lava flows. Please see the related links.
How do natural rocks structures form?
by heat and pressure

What branch of science studies metamorphosis?
Metamorphosis means 'change in form' and is undergone by some animals, which comes under biology (specifically zoology). It is also a process undergone by rocks, which is geology.
How can igneous sedimentary and metamorphic rocks form?
igneous rocks form when hot molten rock cools and solidifiessedimentary rocks form when other rocks erode and the erosion products collect then are buried and fuse together or minerals are deposited by living things and are buriedmetamorphic rocks form when other rocks are buried deep and the high temperature and pressure removes volatiles and modifies crystal structures in the rock
Compressional stresses can form what?
compressed stress
Why would expect to see similar rocks or rock structures in two landmasses that were connected at one time?
Because where they have been broke appart for a long period of time, the rocks started to form.
What is boudinage?
This is a term used in structural geology to describe rocks that have undergone tensile or extensional strains leading them to form an elongated tube like body due to the shearing of the surrounding weaker rock mass.
What is the plural form of stress?
The plural of stress is stresses.
What is the plural of stress?
if it used as a verb, i think the plural of stress is "stresses" but if it used as a noun, i don't know if you can still add "-es" to it~
Can metamorphic rocks form form igneous but not from sedimentary rocks?
Metamorphic rocks can form from both igneous and sedimentary rocks
