Geology explains why mountain ranges exist and how they formed over millions of years.
Understanding the principles of geology helps predict earthquakes and volcanic eruptions.
What is "geology"?

Geology is the study of the Earth’s structure, materials, and processes. Geologists examine rocks, minerals, and landforms, and investigate how the Earth’s surface has changed over time due to forces like plate tectonics, erosion, and volcanic activity. Geology helps us understand natural disasters, locate resources like minerals and fossil fuels, and study Earth’s history and future.
