These are formed when either igneous or sedimentary rocks are changed. Heat and/or pressure will cause the elements in the original rock to react and re-form. Metamorphic rocks are highly ...

What FACTS ABOUT ROCKS do you know? They are abundant on earth, and yet little is known about them. These facts will increase your knowledge of the rocks.

Igneous and metamorphic petrology is the study of rocks formed from molten material and those that have undergone transformation due to heat and pressure, respectively. Recent research in this ...

The characteristics of the rocks that hold fossils can be as informative as the fossils themselves. There are three main types of rock: igneous rock, metamorphic rock, and sedimentary rock. Almost all ...

It depends on what the rocks are made of – and that’s related to how they were formed. There are three main rock types: igneous, sedimentary and metamorphic. These rocks are made of minerals that all ...

There are three main rock types: igneous, sedimentary and metamorphic. These rocks are made of minerals that all have different characteristics. Some will melt into magma or lava – super-hot, ...

Petrology is the study of rocks - igneous, metamorphic, and sedimentary - and the processes that form and transform them. Mineralogy is the study of the chemistry, crystal structure and physical ...
