The theory of plate tectonics explains global patterns of geological activity and continental movement
Primordial Earth
Inside Planet Earth
The Lithosphere
All energy on Earth comes from the sun as light and heat. All life is dependent on that energy; held together in a fragile balance of exchange.
This system supports the
Biodiversity of Life on Planet EARTH

Primordial Earth
Earth formed 4.5 billion years before the present BP.
Red-hot ball of molten rock.
As the planet cooled heat energy was trapped in its core.
The outer layer cooled and became solid
Inner core remains red hot.
New earth is made by volcanos.
Red hot lava spews up from the core. On the surface lava dries to form new land. These new rocks are rich in nutrients.
Earthquakes recycle old rocks sucking them back into the inner core where they are melted down to molten lava.

Inside Planet Earth
Earth is the only planet with a dynamic inner core of layers.
We call this PLANETARY DIFFERENTIATION
Because Earth is constantly changing and recycling LIFE is able to flourish.

The Lithosphere : Earth’s Crust
The Lithosphere sometimes called Earth’s Crust is the hard outer shell of planet Earth.
It is made of two parts
The Lithosphere
The Asthenosphere
The Crust is divided into large plates that fit together like a jigsaw.
These plates ride like rafts on the semi molten rocks below, carrying the land and sea.
We call this movement ~
PLATE TECTONICS

Plate Movement = Recycles Land

10. Plate Movement = Recycled Land
Created by Simone Gorman
Plate Movement = Recycled Land
Caused by hot rock rising from the Earth’s core.
Rocks cool and spread in opposite directions near the surface.
Cool rock sinks back down.
This process pushes and pulls plates in different directions.
RECYCLING OLD ROCKS
Where 2 plates collide, one plate is pushed deep into the core where it melts back down to molten rock.
Living organisms inside the melting rock release carbon dioxide gas.
CREATING NEW ROCK
Carbon dioxide gas returns to the atmosphere through volcanic eruptions.
New earth is spewed from the Earth’s core during an eruption, when it cools it hardens forming new crust.
This process recycles nutrients and influences our ATMOSPHERE.
