地球与环境科学（EaES）的主要和未成年人研究在地球表面及其内部发生的过程，这些过程随时间的演变以及构成地球材料的固体，液体和气体。地球被视为一个动态的物体，在行星的内部和外部，大气层，海洋和生命之间不断进行物质和能量的交换。了解这些地球系统过程对于评估全球环境，其自然变异性以及人类活动导致的变化至关重要。获得地球和环境科学学位可能会导致在工业，公共部门或教育界就业。许多地球科学家在与环境有关的领域建立职业，其中包括预防，控制和修复水和土壤中的污染物。其他人则致力于预测和预防与自然灾害有关的问题，例如地震
Earth and Environmental Science (EaES) majors and minors study the processes that occur at Earth's surface and in its interior, the evolution of these processes over time, and the solids, liquids, and gases that make up Earth materials. Earth is viewed as a dynamic body, with continual exchange of materials and energy among the planet's interior and exterior, atmosphere, oceans, and life. Understanding these Earth system processes is essential for evaluating the global environment, its natural variability, and changes that result from human activities. A degree in earth and environmental sciences may lead to employment in industry, in the public sector, or in education. Many earth scientists establish careers in areas that are environmentally related, which may include the prevention, control, and remediation of pollutants from water and soil. Others work at predicting and preventing problems associated with natural hazards such as earthquakes, landslides, floods, and volcanic eruptions. Employment possibilities also exist in the exploration, use, and management of resources such as water, metals, petroleum, and coal.
