MINERALS
MINERALS ARE NATURAL SUBSTANCES MADE UP OF A SINGLE ELEMENT OR A COMPOUND OF ELEMENTS.
ROCKS
Rocks are formed from one or more minerals.
WHY ARE ROCKS AND MINERALS DIFFERENT.
ROCKS ARE MADE OF ONE MINERAL OR MORE,MINERALS ARE MADE UP OF A SINGLE ELEMENT .
WHAT ARE THE LAYERS OF THE EARTH?
The layers of the Earth are the crust, the mantle, the outer core and the inner core.
DESCRIPTION OF MANTLE
- The mantle is the layer located directly under the sima.
- Mantle is the largest layer of the Earth (1800 miles thick)
- The mantle is compose of very hot dense rock.
- The mantle is very hot.
DESCRIPTION OF OUTER CORE
- The outer core are so very hot
- The metals that are in the outer core are all in the liquid state.
- Earth's outer core is a liquid layer about 2,266 km (1,408 mi.)
DESCRIPTION OF INNER CORE
- Earth's inner core is Earth's innermost part and is a primarily solid ball with a radius of about 1,220 km (760 mi).
- The inner core of the Earth has temperatures and pressures so great that the metals are squeezed together.
- The inner core begins about 4000 miles beneath the crust and is about 800 miles thick.
WHAT ARE THE 3 PARTS OF THE EARTH CRUST
- Mantle:The mantle is a part of a terrestrial planet or other rocky body large enough to have differentiation by density.
- Inner core:Earth's inner core is Earth's innermost part and is a primarily solid ball with a radius of about 1,220 km, according to seismological studies.
- Outer core:Earth's outer core is a liquid layer about 2,266 km thick composed of iron and nickel that lies above Earth's solid inner core and below its mantle.
4 THINGS THAT COULD CHANGE ROCKS
- Erosion.
- Wind.
- Heat.
- Pressure.
