What two forces cause the formation of metamorphic rock?
Heat and pressure.
What is rock that is changed by heat pressure or chemical change?
Metamorphic rocks have been changed by heat or pressure. This can be a change in size, shape, or arrangement of minerals.
How does a sedimentary rocks turn into a metamorphic rock?
By exposure to heat and/or pressure through depth of burial, directed pressure, or proximity to a magma source. Existing minerals can recrystallize, non-hydrous minerals can replace hydrous minerals, new minerals can be formed from the introduction of new ions from heated solutions, and minerals can become flattened and aligned in parallel layers.
How do heat and pressure change sedimentary rock?
A metamorphic rock is formed when sedimentary rock is subjected to heat and pressure!
Why do minerals in metamorphic rocks often rearrange in layers?
The alignment of minerals into bands (foliation) is caused by the massive force of pressure and high temperature which results from mountain building processes caused by plate collisions. The heat and pressure combine to realign the existing minerals from a random orientation to one of parallel orientation, thus creating the visible lines or platy cleavages found in foliated metamorphic rocks. The lines of foliation are created perpendicularly to the force being applied.
How is the orientation of foliation related to stress?
The foliation in metamorphic minerals is always perpendicular to the direction of pressure. E.g. Vertical pressure is applied, the foliation will be horizontal, and vice-versa, the pressure is horizontal you get vertical foliation. From yahoo answers
How are minerals formed in igneous and metamorphic rocks?
Minerals form in igneous rock as magma or lava cools. The minerals will form from the available chemicals in the magma as their crystallization temperature is reached. The sequence of mineral crystal formation from magma is described in the Bowen's Reaction Series. Metamorphic rock minerals are aligned, altered, or recrystallized from existing rock minerals due to the effects of heat and/or pressure.

What type of rock texture results when extreme pressure causes minerals in metamorphic rock to realign or when minerals separate out into dark and light bands?
I do believe that the answer is "foliated". However I am not positive, but I do know that... Banding is another word for foliation, which is the grouping of certain minerals with the rock forming parallel bands that are perpendicular to the pressure that causes its formation. Banding of different minerals give some metamorphic rocks a striped appearance, involving the segregation of light and dark minerals into layers. Good luck with your question and I hope that this information has helped.

Component that changes in size or shape when metamorphic rocks are formed?
Minerals(inorganic solids with a crystalline structure) change in size or shape under the intense heat and pressure to form metamorphic rocks.
What are metamorphic rocks formed from?
Metamorphic rocks are igneous, sedimentary, and metamorphic rocks that have been altered by heat, pressure, or ion exchange. Therefore, there is a wide range of metamorphic rock component material.
What condition produces the distinct layers of flat and elongated minerals in the foliated metamorphic rocks?
High Pressure.
What conditions are required to form parallel alignment of minerals sometimes found in a metamorphic rock?
Heat is one condition that is required to form parallel alignment of minerals sometimes found in a metamorphic rock. The other condition is pressure.
