Geologists have classified rocks into three major groups of rocks which are:

• inorganic, organic and chemical rocks

• igneous, sedimentary and metamorphic rocks

• metamorphic, chemical and non chemical rocks

• sedimentary, inorganic and igneous rocks

Any rock that forms from another rock as a result of changes in heat or pressure (or both) is a:

• chemical rock

• igneous rock

• sedimentary rock

• metamorphic rock

A rock that forms from many small fragments of other rocks is a(n)

• igneous rock

• metamorphic rock

• sedimentary rock

• extrusive rock

The process by which metamorphic rock changes to igneous rock begins with

• melting

• erosion

• deposition

• crystallization

A naturally occurring solid that can form by inorganic processes and that has a crystal structure and a definite chemical composition.

• It´s a rock

• It´s a crystal

• It´s a mineral

• It´s a substance
