Definitions
from The American Heritage® Dictionary of the English Language, 5th Edition.
- noun The process by which rocks are altered in composition, texture, or internal structure by extreme heat, pressure, and the introduction of new chemical substances.
from The Century Dictionary.
- noun The process of metamorphosing, or changing the form or structure; specifically, chemical change and rearrangement of the constituents of a rock by which they are made to assume new forms and enter into new combinations, the most important result of these changes being that the rock becomes harder and more crystalline in structure.
from the GNU version of the Collaborative International Dictionary of English.
- noun (Geol.) The state or quality of being metamorphic; the process by which the material of rock masses has been more or less recrystallized by heat, pressure, etc., as in the change of sedimentary limestone to marble.

- noun geology The process by which
rocks are changed into other forms by the application of heat and/or pressure. - noun zoology The process by which
insects development through life stages -- as, for example, those ofembryo ,larva ,pupa andimago . The life cycle of thebutterfly is one of complete metamorphosis, in which the embryo grows within the egg, hatches into the larval stagecaterpillar , enters the pupal stage within itschrysalis , and finally emerges as an adult butterfly imago.

Examples
-
Some geologists confine the term metamorphism to the changes involved in contact and dynamic metamorphism, and call the resulting products _metamorphic rocks_.
-
Basically, a process called metamorphism caused the basalts in Shenandoah to recrystallize with new minerals, such as chlorite, epidote, and albite, which help give the rocks their greenish hue.

-
Rocks are not permanent in their condition, but at practically all times and places are undergoing some kind of metamorphism which tends to adapt them to their environment.

It is an oil from Neem seeds, it is used as and anti fungal in gardening. .it also smells bad and drives off insects, those that do eat of it have their larval hormones messed up enough they cannot metamorphism to moths, it is also bitter, it has been used as a contraceptive in its native India.

Some metasiltstone or metasandstone occurs, but it is material of very low-grade metamorphism.
-
These mantle rocks also show a type of metamorphism found only in conditions of very high energy release.
