What is geology?
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.
What does geology overlap with?
Geology significantly overlaps all other Earth sciences, including hydrology. It is also integrated with Earth system science and planetary science.
What does geology describe?
Geology describes the structure of the Earth on and beneath its surface and the processes that have shaped that structure.
What do geologists study in order to gain insight into the history of rocks?
Geologists study the mineralogical composition of rocks in order to gain insight into their history of formation.
What determines the absolute ages of rocks?
Geochemistry, a branch of geology, determines the absolute ages of rocks.
