Consider the following discussions and write a minimum 3 sentence response to each discussion by Wednesday 4/13 at 11:59 P.M.

1. What if the Sun suddenly became cooler or hotter than it currently is (pick one option)? What would be the consequences for Earth? Could we somehow live on the Earth?

2. What if the Sun did not rotate? What would be different about the Sun’s activity? How would the lack of a rotation for the Sun affect Earth?

3. Describe at least 3 advantages and 3 disadvantages of observing the Sun from space and describe at least 3 advantages and 3 disadvantages of observing the Sun from Earth’s South Pole.

4. As discussed in Chapter 9, meteorites falling into the Sun could not be the source of the Sun’s energy because the necessary increase in the mass of the Sun would lengthen Earth’s orbital period by 2 seconds per year…what effects this would this mass increase of the Sun cause for the Earth and for humans as the centuries went on?
