"Geology is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which it is composed, and the processes by which they change over time."
Geology is the study of the earth's physical structure, properties, and processes. It is important in environmental science because it helps us understand how natural resources form, how water moves through the earth, and how human activities can impact the earth's geologic processes.
"Geology describes the structure of the Earth on and beneath its surface and the processes that have shaped that structure."
"Geologists study the mineralogical composition of rocks in order to get insight into their history of formation."
"Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their absolute ages."
"By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole."
"Geology provides evidence for plate tectonics."
"Geology provides insights into past climate change."
"Geologists use a wide variety of methods to understand the Earth's structure and evolution, including fieldwork, rock description, geophysical techniques, chemical analysis, physical experiments, and numerical modeling."
"In practical terms, geology is important for mineral and hydrocarbon exploration and exploitation, evaluating water resources, understanding natural hazards, remediating environmental problems."
"Geology is central to geological engineering and plays an important role in geotechnical engineering."
"Geology (from Ancient Greek γῆ (gê) 'earth', and λoγία (-logía) 'study of, discourse')"
"Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with Earth system science and planetary science."
"One aspect is to demonstrate the age of the Earth."
"Geologists study the evolutionary history of life."
"Geology is important for mineral and hydrocarbon exploration and exploitation."
"Geologists use fieldwork, rock description, geophysical techniques, chemical analysis, physical experiments, and numerical modeling to understand the Earth's structure."
"Geology is important for evaluating water resources."
"Geology is important for understanding natural hazards."
"Geology plays a role in remediating environmental problems."
