Answer:
C. its age
Explanation:
Rex is most likely trying to figure out the age of the rock formation. It is usually done by comparing the isotopic ratios of the daughter to the parent and their decay rates.
- This is known as radiometric dating.
- Here an exact numerical age of the rock is usually obtained by measuring these isotopic ratio.
- The rate of decay serves as a clock to measure how far the radioactive material has decayed in time
The theory is that because the oceanic plate is denser than the hotter mantle beneath it, this contrast in density causes the plate to sink into the mantle. The process of a tectonic plate descending into the mantle is termed subduction. Slab pull occurs when an oceanic plate subducts into the underlying mantle.
