explain the formation of three main rock types and there roles in the rock
Types of Rocks Igneous, sedimentary, metamorphic
Types of Rock. Obsidian rocks are igneous rocks that form when lava cools quickly above ground. Obsidian is actually glass and not a mixture of minerals. Metamorphic Sedimentary and igneous rocks which were subjected to more intense pessure or heat and as a result underwent a complete change. Metamorphic rocks form deep within the Earth's crust....
Metamorphic Rocks University of Oregon

INTRODUCTION TO TYPES AND CLASSIFICATION OF ROCKS
Rocks are broadly classified into three groups based on their process of formation. The three major rock types are: 1. Igneous rocks 2. Sedimentary rocks 3. Metarmoprphic rocks Sedimentary rocks makes up to 66% of the earth's crust, with 34 % being the igneous and the metamorphics....

Igneous rock composition and texture
Many different types of igneous rocks can be produced. The key factors to use in determining which rock you have are the rock's texture and composition. Texture. Texture relates to how large the individual mineral grains are in the final, solid rock. In most cases, the resulting grain size depends on how quickly the magma cooled....

Describing Rock Textures ClassZone
The characteristics related to grain size are known as a rock's texture—coarsegrained, finegrained, and glassy are all descriptions of a rock's texture. The texture of igneous rocks can be analyzed to understand how the rock became solid or crystallized from liquid, melted rock. ! Click each image to see a larger version plus information about......

THREE AGENTS OF METAMORPHISM AND THEIR EFFECTS
THREE AGENTS OF METAMORPHISM AND THEIR EFFECTS. Recall that any rock can be changed to a metamorphic rock. Whatever the beginning rock is, it is called the PROTOLITH of the metamorphic rock it is transformed into. Three things contribute in varying proportions to the transformation from a protolith to a metamorphic rock: heat, pressure, and fluids (mostly water with dissolved ions)....

Sedimentary Rocks | Pictures, Characteristics, Textures, Types
There are three basic types of sedimentary rocks. Clastic sedimentary rocks such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris. Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution....
