Keywords

[sediment] Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice.

Sediments are most often transported by water (fluvial processes), wind (aeolian processes) and glaciers. Sediment also often settles out of slow-moving or standing water in lakes and oceans.

Geological keywords, such as “granite”, “lake”.  The definitions are generally taken from the AGI Glossary of Geology.  Keywords with a geographic context (e.g. Cape Smith Fold Belt, Selwyn Basin, Grenville Province) are assigned to a separate category.
