Answer:
Geology
Step-by-step explanation:
I don't know what kind of question this is if you already gave the answer, but I'll put some info on geology just in case :)
Geology is the study of the Earth, the materials of which it is made, the structure of those materials, and the processes acting upon them. It includes the study of organisms that have inhabited our planet, (but are not living anymore). An important part of geology is the study of how Earth's materials, structures, processes and organisms have changed over time.
Hope this helped!! :)
