Geology Study of rocks, minerals, parts of earth

Sedimentary Metamorphic Igneous

Minerals

The Igneous rock is made when the magma is

underground erupts , and the lava cools above

ground.

Igneous rocks are split into two groups. When the Igneous rock cools quickly, the rock is as

smooth as glass. When it cools slowly, air bubbles will get

trapped into the rock, and then the Igneous rock will have spaces

in it.

Granite is a example of Igneous Rock, and people can use it for counters for

their kitchen

Obsidian is used for

sharp edges such as

knives, and arrowheads.

Amphibolite is also a type of Igneous rock. It is used as crushed stone for the

use of road and railroad bed construction.

Rocks metamorphose when they are in a place where it is very hot or the

pressure is high. It is squeezed under the earth for millions of years. The

rocks will often have layers and crystals.

A metamorphic rock is formed by the rock being

crushed between the Earths crust, and heat

and high pressure.

A marble metamorphic

rock is used for making floor

tiles

A quartzite metamorphic rock is used for making

building tools.

A Phylite metamorphic rock is used for making

marble buildings

A Sedimentary rock is made up of about three-quarters of the rocks on the Earth. They are from environments such

as beaches, rivers, the ocean, and anywhere that sand, mud, and other types of

sediment collect.

Many sedimentary rocks are made from the broken bits of other rocks, which

are called Clastic Sedimentary Rocks. The

other types of Sedimentary rocks, are called Chemical Sedimentary Rocks, and is

made up of mineral crystals.

Shale is a Sedimentary Rock and is used as a

filler for paint

Breccia is used for countertops and walk ways.

Sandstone is also a Sedimentary

rock and is used for sharpening

devices, buildings, and

glass production.

The inner core of the earth is the hottest. Its about 1,216 km in the

radius. The inner core is a solid as it is packed together so tightly.

Inner Core

The outer core of the earth is the second hottest. It’s a liquid layer of about 2,266 km. Its also composed

of iron and nickel.

Outer Core

The mantle is divided into two regions. It is made from hot, semisolid rock. Its

about 2,900 km. thick.

Hard and rigid, the crust is the earth’s thinnest layer, and its about 5 km.

thick and under the ocean.

A mineral is a non-living solid that is made of

atoms and elements. The atoms divides the

minerals into many different groups.

A mineral is formed by atoms and elements. A

mineral could be formed by magma, cools and leaves

crystals. When minerals are formed by the sea, it is a

sedimentary-mineral rock. Also, when the mineral is a

metamorphic it forms where mountains start

forming.

The Minerals are Quartz, Talc, Gold, Copper, Silver, Diamond, Mesa,

Feldspars and many more.

The Asychanite is rock is a rock that is sold for millions of

dollars

Many people buy this rock because it is

very pretty to look at it is called a Ajoyt

Crystals are often put on jewelry and sold

for thousands dollars
