🔭 Space and beyond
layers of earth
Crust
thiner than the others
rock
mantle
semi-molten
rocks, aluminium and oxygen
outer core
thick
liquid
iron and nickel
inner core
extremely hot
iron and nickel
dense
Nebula / supernova
giant cloud of dust and gas
explosion of a dying star
can create stars
interstellar is measured in light years
we can find them with advanced telescopes
Tectonic plates
lithosphere
14
Types
continental: thicker
Oceanic: thiner
Pangea
once they were one continent
evidence
magnetic field
continents match like a puzzle
fossils
how a star is formed
gravity slowly collapses to form a proto-star
once temperature and pressure gets high enough at the center they create nuclear fusion
gets bigger and now its called a star
Volcanos and Earthquakes
convection currents
movement off energy
Types of movements
divergent
spreeding
constructive
volcanic activity
away from each other
Convergent
oceanic
volcanic activity
continental
no volcanic activity
destructive
towards each other
transform
lateral siding
no volcanic activity
no mayor effect
Extra
fossils
tell us when animals exited and show us similarities between continents
remains of an animal trapped in a substance
Magnetic field
protect us from the UV rays
we have water due to it
metals control it
tectonic plates contain metals
the magnetic field has moved
Giant impact theory
earth crashed with a mini planet called thia and the remains made the moon
evidence
rotate the same way
other examples in the milky way
the moon has similar materials with the earth exactly the outer core
there are remains of the explosion in the ring of asteroids
