What is geology

 Geology is the study of the Earth's structure, history and processes. Geologists study everything from fossilized plants and animals to minerals and rocks. They explore how these things were formed, where they are found, how they change over time, and what they tell us about the history of our planet. Geology is also a form of applied science that applies these scientific principles in practical ways such as finding natural resources like oil or gold, predicting earthquakes or tsunamis, understanding the causes of climate change, or studying impacts on human health.
