The formation of a mirage is shown in the model here. To the observer, the image appears to be coming from the straight line, when in fact it is coming from an angled source. What BEST explains the observer and the mirage?

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
