Introduction to Stone,Rocks,Applications

There are many definitions of rocks, which the earth is made off. A more acceptable scientific definition of rocks is that; a rock is a natural occurring solid cohesive aggregate of one or more mineral or mineral materials.
Generally rocks can be divided into three major types based on the process of their formation. These are; Igneous rocks, sedimentary rocks and metamorphic rocks.
Igneous rocks are formed by the solidification and cooling of magma in volcanic areas, while sedimentary rocks are formed by low temperature accumulation of sediments in tectonic basins and topographical sinks. Metamorphic rocks on the other hand are formed by application of temperature and pressure on pre-existing rocks. Metamorphic rocks therefore form at great depths, but exposed on the surface due to erosion and epirogenic movements. Each of these three rock types can be further classified in terms of; chemistry, how the form and environment of formation. The distributions of these major rock types are critical in regional mapping of natural resources.
Stone vs Brick
Similarities:
Both stacked-
Mortar Joints-
Differences:
Shape: Brick molded - Stone Cut and Carve
Physical Properties: Brick made/controlled – Stone provided by nature
RockTo the geologist any mass of mineral matter, whether consolidated or not, which forms part of the Earth s crust ... (2) The civil engineer regards rock as something hard, consolidated, and/or load bearing, which, where necessary, has to be removed by blasting. This concept also accords with the popular idea of the meaning of the word.

Stone In geology the word stone is admissible only in combinations such as limestone, sandstone, etc., or where it is used as the name for extracted material - building stone, stone road. It should not be used as a synonym for rock or pebble.
