It's is called sustainability
I would say it’s the second option
Answer:
through glacial deposits and ice cores
Explanation:
Scientists use ice to study ancient climates through glacial deposits and ice cores.
These two sources are fundamental to the study of ancient climates whose salient information has been preserved and locked in time through glacial deposits.
- A place can remain frozen for an extended period of time.
- Some gas bubbles can be trapped in the midst of ice being formed.
- These bubbles and compacting sequences of ice layers are used to interpret ancient climates.
- Ice cores are drilled an collected in barrels where they are taken to the laboratory for further studies.
- It is possible to even date each ice layer.
So, the solution is through glacial deposits and ice cores.
C. Ultraviolet light shining on the minerals will cause them to give off visible light.
