理学学士-地球科学

地球科学是涉及地球的自然科学
Earth scientists, also called geoscientists and geologists, study the origin and evolution of oceans and continents. This includes the formation of mountain ranges, valleys, glaciers, and lakes. They also study the causes and effects of natural hazards, such as those created by land- and rock-slides, earthquakes, floods and droughts, sea- and lake-level changes, and volcanic eruptions.Earth scientists also investigate:the origin, migration and quality of groundwaterthe monitoring and mitigation of river and coastal erosion or floodingsea- and lake-level rise and fallclimate changeThey study the origin of Earth's natural resources and are extensively involved in the discovery and environmentally responsible development of metallic minerals, salts, water, clay, sand, gravel, cement, coal, oil and natural gas that society uses for construction of the built environment, agriculture and drinking water, communications and energy.Urban and land-use planning, and efforts to clean up our environment, require a sound knowledge of earth-science processes.
