Geologists can determine the actual age of features on a planet by the radiometric dating method in which the age of the rocks is calculated by the natural decay of the radioactive isotopes of elements such as carbon.
In the radiometric dating method, the radioactive minerals in rocks are used. The radioactive isotopes, which are the chemical elements, naturally break down and decay to form a new isotope.
Each radioactive element has a unique decay rate which is known. Hence, the radioactive isotopes are crucial for the geologist to compare and identify the age of the rocks and furthermore, the planet.

Answer:
within tectonic plates themselves
Explanation:
The eight-digit grid coordinate gives exactness to the nearest 10 meters. Read below about the grid coordinate of the above given map.
<h3>What are the eight-digit grid coordinates for benchmark 86 (circled in red)? </h3>
Grid coordinates are said to be correctly target to a definite area, using a map that starts with upright and straight lines of same spacing and signals connected to every line to define out a destination.
The traverse vertical and horizontal lines have different figures and make little squares defined as grid squares. The more digits in the coordinate of a boundary, the improvement in precision an eight-digit provides a accuracy to the nearest 10 meters.
Therefore, the correct answer is as given above.

I would say that the country with the longest average growing season is Saudi Arabia.
I hope this helps you!
