Depletion of Ozone Layer — reality or falsification? Natural philosophy as a predecessor of natural sciences — correlations and differences.
Provide a detailed history of the changes that occurred on the planet in the past fifty years? In terms of weather changes and geological changes, what can we predict about the effect on the Earth if its orbital spin were to slow down or speed up?
Where are the largest magma chambers beneath the Earth that might be biggest volcanic super-eruptions threats to people around the world? How important is the West Antarctic ice sheet to the rise or fall of global sea levels and what do we know about its stability? What are the differences to how the oceans, lakes, and rivers are affected by solar eclipses and lunar eclipses? What do we know about plant life on earth and possibilities of finding life on any other planetary body in our solar system?
What does one need to do to become an Earth scientist? How many years of graduate and post graduate work in the field is required?
