Compare the view of the Moon at about 110x to 125x between the three telescopes. (You won't be able to get exactly the same magnification for all three scopes, but there should be an eyepiece choice that gets into about that range for each scope.) What are two things you notice that are different about the views

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
