Geologic maps are most recognized by their colors/symbols which represent different rock units/rock ages. If you observe a geological map, you would notice different areas have different colors. These colors usually denote similar characteristics in rocks surrounding an area (age, type). Symbols are denoted by a capital letter followed by lower case letters. The capital letter represents the age of the unit.
I think it is None of the above
Should be Australia I think
Sometimes people don't call it an island though so the next biggest island is Greenland
The answer is A. It is based on facts which are non-testable.
The idea that the Solar System originated from a nebula was first proposed in 1734 by Swedish scientist and theologian Emanual Swedenborg. This theory is the most widely accepted model explaining the formation of our Solar System. Perhaps the most convincing line of evidence supporting this theory are observations of the same process currently happening elsewhere in our Galaxy.
