The Atmosphere comes from greek word atmos meaning air. It is ~480 km thick. It is made up of 78% nitrogen, 21% oxygen and 1% other gasses.
The Biosphere comes from the greek word meaning Bio which is life. It is composed of the parts of earth where life exists.

Crust
Mantle
Outer Core
Inner Core
Plate tectonics
In 1915 a man named Alfred Wegener who suggested that there was a continental drift. South America and Africa fit together and made one supercontinent called Pangea. He found fossils of the same species around different continents and 200 million years ago pangea started to break up. There are different plates
Diverging Plates (Spreading)
Converging Boundaries (Colliding)
Transforming Plates (Sliding)
Ring of Fire
The ring of Fire is where 75% of the world’s volcanoes are located and 90% of the world’s earthquakes are located. The area is a 25,000 mile line of volcanoes and is on the edge of the pacific ocean.

Selective Cut
Shelterwood Cut
Clear Cut: Remove all of the trees in one area and in one operation. It leaves a barren landscape.
