Resources from rocks and The Rock CycleReported by:Alyssa May B. LiwagII-BSBTResources from Rocks: (sedimentary and metamorphic)

Quick Review of Types of Rocks

Rock Cycle In this lesson Gypsum- is a very soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO42H2O. It can be used as a fertilizer, is the main constituent in many forms of plaster and is widely mined.

Uranium- is a silvery-white metallic chemical element in the actinide series of the periodic table, with symbol U and atomic number 92.


Three sedimentary rocks are very common:shale-fuelsandstone- popular building material from ancient times. It is relatively soft, making it easy to carve. It has been widely used in constructing temples, cathedrals, homes, and other buildings. limestone- construction, source of calcium, cosmeticsResources from RocksSedimentary Rocks Crude oil- is a naturally occurring flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds.


How Crude oil is Formed?

Natural gas - is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, with other hydrocarbons, carbon dioxide, nitrogen and hydrogen sulfide.

Ground water- is water located beneath the earth's surface in soil pore spaces and in the fractures of rock formations.Resources from RocksSedimentary Rocks Fossils- are the preserved remains or traces of animals (also known as zoolites), plants, and other organisms from the remote past.


Slate- an be made into roofing slates, which are installed by a slater and are a type of roof shingle, or more specifically a type of roof tile.

Resources from RocksMetamorphic Rocks

Schist- constitute a group of medium-grade metamorphic rocks, chiefly notable for the preponderance of lamellar minerals such as micas, chlorite, talc, hornblende, graphite, and others.


Marble- used for sculpture and construction.


Quartzite- Because of its hardness and angular shape, crushed quartzite is used as railway ballast, can also be decorative stone and may be used to cover walls, as roofing tiles, as flooring, and stair steps. High purity quartzite is used to produce ferrosilicon, industrial silica sand, silicon and silicon carbide.Resources from RocksMetamorphic Rocks

ROCK CYCLE Igneous- rock formed from a volcano.

Sedimentary- rock formed from sediments.

Metamorphic- rock that undergoes additional pressure and temperature.

Rock Types Every rock and rock fragments is a part of the earths rock cycle.

The rock cycle demonstrates the earths ability to recycle its materials.

Are rocks are constantly changing very very slow. Rock Cycle

Rock Cycle The rock cycle is an ongoing process, beginning as rocks are pushed up by tectonic forces, and eroded by wind and rain. The eroded rocks travel by wind or moving water until they are deposited, settling into layers. Additional eroded rocks may bury these layers until heat and pressure change the underlying layers to metamorphic rock. More eroded rocks may squeeze and press the layers into sedimentary rocks. Rocks can also be sunk down into the lower layers of the earth by plate tectonic processes. Buried rocks may also melt and recrystallize into igneous rocks. Metamorphic, sedimentary, and igneous rocks may then be pushed up by tectonic forces, starting the rock cycle again. Summary of Rock CycleThe End
