The first stage in designing your presentation is to make a list of questions that will enable you to research the topic.
your presentation should answer these questions: where is the magnet that causes earth’s magnetic field? what is this magnet made of?
what is the solar wind? what happens when earth’s magnetic field interacts with the solar wind?
does earth’s magnetic field protect the planet?
what are the van allen belts, and how are they related to earth’s magnetic field?
what are auroras, and how are they related to earth’s magnetic field?
how does the principle of electromagnetism explain the interaction between earth’s magnetic field and the solar wind? write down two additional questions about earth’s magnetic field that will make your presentation more informative.

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
