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.

b. Antarctica's ice
Explanation:
Earth is flatter at the South Pole than the North Pole because of the weight of the Antarctica's ice.
The Antarctica ice cap is the largest single mass of ice on earth. It covers almost 14 million square kilometers and it weighs 26,500,000 Gigatons.
As a result of this heavy weight, it compresses the South Pole of the earth causing the earth to be flatter at the South Pole.
This gives the Earth its slight pear shape.
