The goal of environmental science is to demonstrate the importance of the interrelationships between the different physical and biological components of the biosphere and to develop a set of scientific concepts and concepts to directly assess the causes and possible relationships to crises. environmental shaking our societies.
Earth's environment is constantly changing, especially in recent years with the advent of industry, deforestation and increased pollution that has disrupted many systems at the level of the biosphere (physical and biological), so the need of environmental scientists so that it can predict future events and how to restore the biosphere system.

Explanation:
Core samples are most often taken with their long axis oriented roughly parallel to the axis of a borehole, or parallel to the gravity field for the gravity-driven tools. However it is also possible to take core samples from the wall of an existing borehole.
 
        
             
        
        
        
I'm not exactly sure what specifically you are asking for in relationship to balancing equations, but I have some examples with working out so you can examine them and try to go through the steps with them.
Hope this helps! <3
