Causes of metamorphism
By: Francis Harris
Metamorphic rocks are one of three classes of rocks, distinguished from both sedimentary and igneous rocks, because of the way they form. The process that forms metamorphic rock is known as metamorphism, a word derived from the Greek "meta" and "morph", meaning "change/beyond" and "shape/form"...
Facts about chemical sedimentary rocks

Chemical, or crystalline, sedimentary rocks contain mineral crystals that are made from dissolved water within them. These rocks are classified by the chemistry of the minerals. Their formation does not depend on any chemical or biochemical process. There are three common groups within chemical sedimentary...

Metamorphic rocks are formed when existing rocks (igneous, sedimentary or even other metamorphic rocks) are subject to agents of change. These causes of metamorphism such as heat more than 200C (but below the boiling point of the rock) and pressures higher than 300Mpa break down...

There are six general types of metamorphism established by geologists. Metamorphic rocks are created when sedimentary, igneous, or other metamorphic rocks are exposed to extreme heat, pressure, and occasionally chemical solutions. The types of metamorphism are distinguished by the factors involved and also the location...
Facts about metamorphic rocks
By: Kimberly Napier
Metamorphic rocks occur when rocks go through a change. This change happens under high temperatures, pressure and, at times, chemical fluids. When a rock goes through metamorphosis, it changes its texture and even the mineral composition. Metamorphic rocks are changed through a solid state unlike...

A Metamorphic rock is an igneous or sedimentary rock that has changed from its original form to another completely different rock, through a process called metamorphism. Metamorphism involves the alteration of existing rocks into new rocks either with intense heat or intense pressure or a...

Metamorphic rocks are ones that have undergone a change of form during a process called metamorphism. Metamorphic rocks tend to form deep in the Earth’s crust where immense heat and pressure alter the chemical composition of a rock creating a new type in the...
Understanding the rock cycle
By: Retha Boswell
The rock cycle describes the continuous series of changes that rocks undergo. The changes occur over millions of years, destroying old rocks and making new rocks. It is not as clear cut as the very simple water cycle, but is still easy to understand. There...

Metamorphic rocks are those rocks which have been changed by metamorphic processes, typically heat and pressure increases due to one or more physical factors-such as plate tectonic movements of the Earth's crust-that create a new environment for the rock. The new environment makes the rock...

Coal is an organic sedimentary rock due to the fact it is created from the remains of plant and animal material. Organic rocks form as the result of accumulating debris from plants and animals. Over time organic material will break down leaving mostly carbon behind...
