Scientists who study the earth's layers are called geologists.  Since they cannot see the inside of the earth they use geographical clues to help them.  These clues are gathered from activities such as volcanoes and earthquakes.  From these clues geologists hypothesize (make an educated guess) what they think the earth actually looks like. Geologists believe the earth is neither liquid nor solid all the way through.  It is a made up of different layers.  Some of these layers are solid.  Some are liquid, and some are both.  The layers of the earth have special names.  They are the crust, the mantle, and the core.  These layers vary in width and temperature.  Look at the picture below. The thin crust, or outer layer of the earth is made mostly of rock.  The thickness of this layer varies from 3 to 34 miles.  Below the crust is the mantle.  The mantle is about 1,800 miles thick and made mostly of solid rock.  It is the thickest layer of the Earth. The mantle is also very hot - about 5,400 degrees F in some spots.  The center of the earth is called the core.  It is about 2,200 miles thick.  The core is extremely hot - about 7,200 degrees F.  The core is further divided into an inner core and an outer core.  The outer core is a liquid layer of melted nickel and iron.  The inner core is made of solid nickel and iron.

How minerals are identified?

Properties of materials

A mineral is a solid whose particles make a pattern. Soil and rocks are made of minerals. There are many kind of minerals, but only a few dozen make up most of the rocks of the Earth.

Every minerals has certain properties.

Hardeness: Some minerals are harder than others. The Mohs scale is used to tell how hard a mineral is. The scale rates the hardness from 1 to 10. Talc is the softest, with a scale of 1 and diamonds the hardest, with a scale of 10

Magnetism: Some mineral have magnetic properties. Pyrrhotite and magnetite are minerals that are strongly magnetic.

Luster: It is the way a mineral’s surface reflects light. A mineral luster can be glassy, earthy, metallic, waxy, silky or pearly.

Shape: Not all mineral shave a specific shape. But pyrite, which is shaped as cube. A mineral’s shape will cause the mineral to break in specific patterns.

Streak: Scientist rub materials on a hard, rough surface. This makes a powder. The color of the powder it’s a mineral streak.

Texture: It is how a mineral feels. Textures may be sandy, sticky, smooth, or powdery.

                                

Using Properties to Identify Minerals

Scientist record the properties of unknown minerals. Then they compare these observations to minerals they have already observed.
