Rock layers can be dated using radiometric dating because it can change how we think about them. This allows us to determine the relative ages of these rock layers.
Rock is a naturally occurring, cohesive aggregation of one or more minerals in geology. These aggregates often form recognisable and mappable volumes and make up the fundamental component of the solid Earth. According to the processes that led to their formation, rocks are typically categorized into three major classes.
These three categories of rocks are: (1) igneous rocks, which have crystallized from molten rock known as magma; (2) sedimentary rocks, which are made up of pieces of other rocks or of substances that have precipitated from solutions; and (3) metamorphic rocks, which have been created from either igneous or sedimentary rocks under conditions that have changed their mineralogical composition, texture, and internal structure. These three classes are further divided into multiple groups and types based on a variety of variables.

Answer:
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.
I think that they can either use fossils or age of rocks
