Earth and Environmental Sciences

23 glossary terms

Earth and environmental sciences examine the planet as a single, coupled system. The atmosphere, oceans, landforms, and living communities are not separate domains; they influence one another on timescales ranging from seconds to millions of years. The terms in this section cover the processes that shape landscapes, the cycles that move water and carbon between reservoirs, and the measurements scientists use to track change. You will find geological concepts like unconformity alongside modern ideas such as yield gaps in agriculture or wetland restoration. Together they frame how scientists diagnose what the Earth is doing now, and what it has done before.

Water Footprint Calculation

Water footprint calculation is a method used to measure the total volume of freshwater used directly and indirectly by an individual, community, business, or nation, accounting for consumption and pollution throughout the production and supply chain.

Satellite Remote Sensing

Satellite remote sensing is a pivotal technology that enables comprehensive observation and analysis of Earth's surface and atmospheric conditions from space, significantly advancing fields such as environmental science, agriculture, and climate research.

Ocean Acidification

Ocean acidification causes involve various processes that lead to a reduction in ocean pH levels, predominantly driven by the absorption of atmospheric carbon dioxide.
