Like many other scientific disciplines, geology helps us make sense of the world around us. The more you understand what makes up the planet, the more you'll appreciate how Earth's systems operate. You'll also see how geology intertwines with other sciences, from biology to physics to chemistry and more. The study of the Earth and its materials seeks to solve problems like climate change and mitigate the risk of natural disasters. Geology also points to new ideas and discoveries that can lead to innovations that improve society.
