Document Summary

Eesa01h3 f: lecture 3 - earth"s systems, ecosystem ecology and global. Major geological and biogeochemical cycles on earth: carbon cycle, nitrogen cycle, mercury cycle, others. Mantle moves slowly and moves with it tectonic plates pertaining to the earth"s crust. The lithosphere is made up of 12 major plates, as well as slower moving minor plates. Three processes form the foundation for ecological processes on the surface of the. Divergent boundary: along divergent boundaries, plates moves apart from each other. Plates move gradually away from the boundary, and magma rises to the surface through cracks along the boundary. Transform boundary: along transform boundaries, plates move adjacent to one another. This causes frictions, which lead to earthquakes. Convergent boundary: along convergent boundaries, plates move towards one another. This can lead to subduction, one plate moving beneath another, if there are differences in density. This can lead to volcanos or mountain formation.
