Earth Flashcards
What is the sphere that holds all liquid water
Hydrosphere
What is the sphere that contains all living organisms
Biosphere
What is the sphere that contains all air
atmosphere
What is the sphere that contains the non-living and the rocks connected to the crust
Geosphere
Crust:
Outermost layer of solid rock, made of light materials such as basalt and where humans live
Mantle:
A semi-solid layer of magma made of elements such as iron and silicon and is hotter than the crust
Core:
A solid (due to pressure) inner core made of heavy metals such as iron and nickel and the core is the hottest
First mechanical layer:
Lithosphere
Second mechanical layer:
Asthenosphere
Third mechanical layer:
Mesosphere
Fourth mechanical layer:
Outer Core
Fifth mechanical layer:
Inner Core
1st Compositional Layer:
Crust
2nd Compositional Layer:
Mantle
3rd Compositional Layer:
Core
3 Types of Rocks: Igneous
Created from lava/ magma and cooling
3 Types of Rocks: Sedimentary
Created from sediments weathering and eroding and the compaction of said sediments`
3 Types of Rocks: Metamorphic
Created from extreme heat and pressure of igneous or sedimentary rocks
Has wavy layers
Metamorphic
Has cake layers
Sedimentary
Foliated Rock
Metamorphic with visible wavy layers
Non-Foliated
Metamorphic with no visible layers
Intrusive
Igneous Rock that has large crystals (formed underground)
Extrusive
Igneous Rock that has holes or a glassy appearance (formed quickly outside)
