Geosciences is a highly interdisciplinary concentration employing principles from physics, chemistry, and biology to understand the structure of the Earth and other planetary bodies. Concentrators can study Earth and planetary interiors, including the formation of rocks and minerals, movement of the Earth's tectonic plates, and the circulation of the planets' core and mantle. Other areas emphasize surface processes, such as the movement and storage of water.

This concentration is a good choice for students who seek a broad scientific understanding of the processes that shape the physical world around us. The ScB requires more (19) courses, including a research course.

Students in Geology-Biology apply principles from geology, biology, chemistry, and physics to understand how major components of the Earth, such as its atmosphere and oceans, interact with and sustain life in the past, present, and into the future. Many courses emphasize climate change, environmental pollution, and biogeochemistry, so this concentration is a good one for students interested in studying the environment. Other areas emphasize Earth history, including climate change, extinction events, and using the Earth’s sedimentary record to investigate environmental change. The ScB requires more (19) courses, including a research course.

Geochemists investigate low-temperature and high-temperature processes operating on scales that range from atoms, to the Earth, to the solar system. Low-temperature geochemistry focuses on chemical and biochemical processes on and near Earth's surface, including environmental geochemistry, pollution in the ocean and freshwater bodies, and how the Earth's geochemical record reflects past climate conditions. High-temperature geochemistry focuses on the formation and evolution of the Earth and other planets, magma formation and properties, volcanic activity, and metamorphism. The ScB requires more (19) courses, including a research course.

Geophysics addresses many pressing and fascinating topics including Earth's changing climate, the mitigation of natural hazards such as earthquakes, volcanic eruptions and landslides, and the internal structure and dynamics of our planet. This concentration is a good choice for students who enjoy quantitative thinking and are keen to study the Earth, its environment, and other planets. The ScB requires more (19) courses, including a research course.
