Geosphere
The layers
Crust
The thinnest
Earth´s surfaces
Two types
Continental crust
oceanic crust
Common rocks
Basalt
Slate
Granite
Mantle
It ocupies most of the interior of the Earth
Most common rock: Peridiotite
It solid but soft
Core
Bassically made of iron and rikel
The hottest part of the geosphere
Two parts
Outer core
Liquid
Inner core
Solid
Rocks
Caracteristics of rocks
Composition
One mineral
Several minerals
Origin
Sedimentary
Are formed from the sediments or fragments of other rocks
Types
Sandstones
Clays
Conglomerate
Metamorphic
Can be formed by extreme pressure or heats
Some of then have layered form called folliation
For example
Schist
Gneiss
Slate
Igneous
Made up of lava or magma from the Earth´s mantle solidifies
Volcanic rocks
The cooling process happens quickly
Glassy appearence
Sometimes they trap bubbles inside
For example
Pumice
Obsidian
Basalt
Plutonic rocks
The cooling process happens slowly
Peridotite
Granite
For example
Minerals
Natural
Inorganic
Solid
"Chemical Formula "
The physical properties of minerals
Crystaline estructure
Nearlly all minerals have a crystalline estructure
For example
Quartz
Pyramite
Colour and streak
Some minerals have a characteristic colour
For example
Sulphur
Yellow
Malachite
Green
Lustre
Reflects lights
Metallic
Glassy
Silky
Pearly
Adamantine
Matle
Other properties of minerals
Hardness
Itś measured by the
MOHS SCALES
For example
Talc
1
Diamond
10
Tenacity
The resistance a mineral has to breaking or bending if it is hit or deformed
If the mineral is easy to break it is
BRITTLE
If not it is
TOUGH
Fracture and clevage
These describe how a mineral break
If it breaks in to irregular shaped fragments we called FRACTURE
If it breaks in to straight lines we call it clevage
