This exam is entirely multiple choice or true/false. A=T, B=F TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false. 1) The photosphere is about 100 times the diameter of the Earth, and large sunspots are larger than our whole planet. 1) 2) Granulation is the most obvious proof of solar convective energy transport. 2) 3) The solar corona is much cooler than the Sun's surface, hence we must wait for a total solar eclipse to glimpse it with the naked eye. 3)...
