By examining tree rings and ice core samples, climatologists are able to determine the environmental and climate situation prevalent at the time the tree was growing and when the water froze.
Because they want to check what is in the core of the earth.
In the deep ocean, the initial core sample layer would consist of a pasty ooze, unlithified, consisting mainly of organic matter. After that, it would pretty much be basalt, an igneous rock.
if you look at the stump there should be rings around in the middle how ever many rings are in the middle should be how old the tree is.If one ring is bigger than another it means that year was rainer so the tree grew more. --------------- You can also do it with out killing the tree by drilling a core sample from it. A narrow hollow auger is screwed into the tree until it reaches the center. Then it is pulled out and a long tube of wood comes out with it. Kinda like core samples from the earth only on a smaller scale.
Geologists collect core samples to study the composition and structure of rock layers beneath the Earth's surface. These samples can provide valuable information about the geological history of the area, help in identifying potential mineral deposits, and aid in understanding the overall geologic structure of a region. Additionally, core samples are useful in oil and gas exploration to determine the presence and quality of hydrocarbon reservoirs.
The core test procedure involves drilling a borehole into the earth's subsurface to extract cylindrical rock samples, known as core samples. These samples are then analyzed in a laboratory to determine properties such as composition, porosity, permeability, and other physical characteristics. The results of the core test help geologists and engineers understand the geological properties of the site for various purposes, such as mineral exploration, environmental assessments, or geotechnical investigations.

The size of a tree's trunk does not necessarily indicate its age. Factors like species, environmental conditions, and growth rate can all affect trunk size. Tree age is better determined by counting growth rings, conducting core samples, or historical records.
Studying tree rings, Dendrochronology is one way.Studying ice cores is another, in particular looking at the ratio of 16O to 18O. This ratio (in precipitated water) is sensitive to the ambient temperature.

Core, rock, and regolith samples.
Geologic core sampling serves a number of important purposes, such as giving scientists information regarding variations of climate. It also provides information about sedimentary composition, and various species.
