Geosphere :desert_island:
The layers of geosphere:
Mantle
Most common rocks: Periodite
It's solid but soft
It occupies most of the interior of the Eatth
Core
The hottest part of geosphere
Two parts
Outer-Liquid
Inner-Solid
Barically made of iron and nickel
Crust
Two types
Continental crust
Oceanic crust
Common rocks: Granite,basalt,slate
Earth's surface
The thinnest layer
Minerals:
Colours and streak:
Some minerals have a characteristics (colours,streak,form) {Sulphur or Malachite}
Most minerals have or can come in several colours {Quartz}
Other properties:
Hardness:
It's the resistance of a minerals to being strached by another minerals or objects
It's measured using the Mohs scale
For example:
Talc
Diamond
Types of rocks:
Metamorphic rocks:
Some of them have layered form (foliation)
For example:
Schits=It's crystals can be seen easly
Gneiss=This is formed of larger crystals than schits
Slate=It has very tiny crystals,not visible to the naked eye
They have been transformed over the time by intense heat and pressure, deep under the ground
Sedimentary rocks:
Types
Clays
Sandstones
Conglomerate
These are sediments rocks with grains
Joining the clasts together is a finer material called Matrix
They have formed the compaction of {Sediments,fragments of others rocks
Plutonick rocks:
They often have crystals that are easy to see (they solidifies slowly)
For example
Granite
One of the most used in construction
The most abundant rock on land
The most abundant rock in mantle
They are formed when magma under the Earth's surface cools and solidifies
