Winter Term 2026 (1940)

EAS 100 - Planet Earth

3 units (fi 6)(EITHER, 3-0-3)

Introduction to the origin and evolution of the Earth and the solar system. Introduction to plate tectonics and the rock cycle. Simple energy balances and interactions between radiation and the atmosphere, land, oceans, ice masses, and the global hydrological cycle. Evolution of life, biogeography, and global climate in the context of geologic time. The carbon cycle. Human interaction with the Earth. Mineral and energy resources. This course may not be taken for credit if credit has been obtained in EAS 200 or 201.

LECTURE B1 (83189)

2026-01-05 - 2026-04-10
MWF 10:00 - 10:50



EAS 201 - Earth Science I

3 units (fi 6)(EITHER, 3-0-0)

A non-laboratory introduction to the origin and evolution of the Earth and the solar system. Introduction to plate tectonics and the rock cycle. Simple energy balances and interactions between radiation and the atmosphere, land, oceans, ice masses, and the global hydrological cycle. Evolution of life, biogeography, and global climate in the context of geologic time. The carbon cycle. Human interactions with the Earth. Mineral and energy resources. This course may not be taken for credit if credit has been obtained in EAS 100 or 210. (Note: EAS 201 and EAS 200 are considered to be equivalent to EAS 100 for prerequisite purposes).
