Geology is an Earth science concerned with the solid Earth, the rocks of which it is composed, and the processes by which they change over time. Geology can also include the study of the solid features of any terrestrial planet or natural satellite such as Mars or the Moon. Modern geology significantly overlaps all other Earth sciences, including hydrology and the atmospheric sciences, and so is treated as one major aspect of integrated Earth system science and planetary science.

It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates.
Geologists use a wide variety of methods to understand the Earth's structure and evolution, including field work, rock description, geophysical techniques, chemical analysis, physical experiments, and numerical modelling. In practical terms, geology is important for mineral and hydrocarbon exploration and exploitation, evaluating water resources, understanding of natural hazards, the remediation of environmental problems, and providing insights into past climate change. Geology is a major academic discipline, and it plays an important role in geotechnical engineering.
I like Geology because Ive been obsessed with rocks since I was a toddler. Whenever I would go to the lake I would collect them, and put them in with my collection. When I got a little bit older, and I went on trips to different citys or states, I would go to tiny gift shops at the towns mall (or sometimes it would just be a little store in town square) and my grandpa and I would get small handfulls of rocks/crystals and were able to take them home in a small poutch. Aside from that, I Ive also liked them because I think its cool how some of the rocks people find could have been in a completely different state before they found it (or when it was created), so I just think its a very cool cycle for the rock.
I think that Geology is cool because its not just the study of rocks, its also the study of how they change. The earth is a big rock, with many layers, Geologists (a person who studies Geology) also study things like that. Geology looks at some of the most important issues in society today including energy sources and sustainability, climate change, the impacts of developments on the envirnment, water manegment, mineral resources and natural hazards. Geology can solve a lot of the worlds problems!:)
My favorite things in Geology are the study of rocks. To be honest, Ive always loved the study of rocks. I actually have a journal of all the different rocks I have. Although, if I had to pick certain aspects of the study of rocks I would pick these three things...
