Crustal Geology: An Introduction

Crustal geology is an important branch of geology that studies the Earth"s crust and its related phenomena. The crust, which makes up about 0. 14 percent of the Earth"s mass, is the outermost layer of the Earth"s solid Earth and includes the earth"s surface, including mountains, valleys, and oceans, as well as the continental and oceanic shelves. The crust is divided into the upper crust and the lower crust, with the upper crust being further divided into the superficial layer and the deep-seated basement, while the lower crust consists primarily of dense materials such as mantle and asthenosphere materials. Understanding crustal geology helps us better understand the formation and evolution of the Earth"s surface, as well as the relationship between tectonic activities and climate change.
