Explanation:
The sea level is tied to glacial growth as a result of the changes that occur.
The glacial growth brings about a decrease in sea level.
Glacial growth occurs when water is evaporated and forms ice which is the
sold state of water as a result of the low temperature in the environment.
The ice formed brings about a decrease in sea level.
However, when the ice melts it leads to an increase in the sea level as the
liquid water formed from the ice which flows into the water bodies thereby
bringing about an increase.

<h2>Answer: fossil groups
</h2>
William Smith was a British engineer and geologist born in 1769. He is known for having developed the first geological map, based on his observations of the rock layers (strata).
It should be noted that during his studies of these strata, Smith realized that each stratum had certain types of fossil groups, different from the others, as it advanced vertically.
In addition, he observed that in distant places the strata showed the same characteristics and the fossils were always the same at the same level, despite the samples being kilometers far apart from each other.
From there, Smith determined a way to recognize a specific stratum (regardless of its horizontal location) by the fossil remains it contained.
