Subaerial

In natural science, subaerial (literally "under the air") has been used since 1833, notably in geology and botany, to describe features and events occurring or formed on or near the Earth's land surface. They are thus exposed to Earth's atmosphere. This may be contrasted with events or features located below a water surface, events or features located below a sea surface, events or features located below ground, or events or features located below glacial ice such as ice sheets.
