Rock Cycles
Igneous Rock
igneous rock is a type of rocks that are formed when molten rock cools to a soil state they are found at volcanoes on the surface of earth or while melted rock is still inside the crust

three examples of igneous rock is andesite, basalt, dacite

adeiste- fill in construction and roading industries

basalt- used in construction (e.g. as building blocks or in the groundwork), making cobblestones (from columnar basalt) and in making statues

dacite- Dacite is sometimes used to produce crushed stone

Sedimentary Rocks
Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms

three examples of sedimentary rock is sandstone, limestone, and shale.

Sandstone-Sandstone is a sedimentary rock composed mostly of quartz sand, but it can also contain significant amounts of feldspar, and sometimes silt and clay

Limestone- is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite)

Shale- is commercially important. It is used to make brick, pottery, tile, and Portland cement

Metamorphic Rock
Metamorphic rock feels like crystalline and often have a “squashed” (foliated or banded) texture

Three types of metamorphic rock is- Phyllite,Schist,Gneiss

Phyllite- Phyllite is a foliated metamorphic rock rich in tiny sheets of sericite mica. Phyllite is a durable and soft rock and used as decorative aggregates, floor tiles, and as exterior building, or facing stone

Schist- It is used inbuilding houses or walls

Gneiss- Gneiss is a common and widely distributed type of metamorphic rock
