Document Summary
4. 375 billion years old, plus or minus 6 million years. Just 100 million years after the moon impact. We couldn"t have these be stable without the magnetic field. Solid fe core surrounded by liquid fe core interacts with the electrical field of the sun to generate magnetic fields. Ionized gas emitted from the sun flowing radially outward through the solar system and into interstellar space. Extension of the solar corona to very large heliocentric distances. Solar wind and temperature are responsible for blowing gases away from the inner planets (rocky) and towards the outer planets (gaseous) in the solar system. Green is the most common color as the solar wind hits the oxygen at around 96 km. Problems with electrical grids (quebec in 1989) Solar flares tell us about what might happen if the field strength decreases too. First recorded use of a compass for navigation: zheng he (1371-1435)
