ROCKS AND MINERALS

ROCK CYCLE

• It is a diagram that show how rocks change.
• It is either changed from sedimentary to metamorphic to igneous.
• Rocks that naturally form in or on earth.

SEDIMENTARY ROCKS

• Sedimentary rocks form when sediments combine.
• Some are eroded away from wind and water.
• They eventually become compressed and cemented.

METAMORPHIC ROCK

• Forms deep below earths surface.
• Forms under heat and pressure.
• This rock has ribbon like layers.

IGNEOUS ROCK

• Forms when metamorphic,and sedimentary rocks mix into magma.
• This rock can be intrusive,or extrusive igneous rock.
• Igneous rock has a glassy surface,and it forms when it cools down.

INTRUSIVE ROCK

• This is a igneous rock.
• Forms under earth,and in volcanoes.
• Forms when it cools slowly,bigger crystals.

EXTRUSIVE ROCK

• This is a igneous rock.
• Forms on the earths surface.
• Forms when it cools quickly,smaller crystals.

MINERALS

• Has a crystal structure.
• It is a organic(doesn't contain carbon).
• Has a definite chemical makeup.

SILVER

• It is like gold,but stronger.
• It is crystallized as cubes.
• It is used for coinage,jewelry,and etc.

BERYLLIUM

• Is a light metal.
• It's a strong metal.
• It probably will corrode.

SULFUR

• It is really smelly,but very useful.
• Produced and consumed in chemical industry.
• Formed in sulfuric acid.

COAL

• Coal occurs in nature.
• It can be sedimentary,or metamorphic.
• It's compressed vegetation from dead animals.

OIL

• It is found in a liquid form.
• This is a good burning fuel.
• It has a natural color of black.
