depression
Let an agent handle landform depressions by type, formation, location and hazards, and separate depression as a mental health condition and as an economic downturn.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle landform depressions by type, formation, location and hazards, and separate depression as a mental health condition and as an economic downturn.
A landform sunken or lower than its surroundings, such as a basin, hollow, sinkhole, crater or an area below sea level like the Dead Sea depression; formed by tectonics, erosion, dissolution or collapse.
What it is for: Describing landscapes, hydrology and hazards.
It can be identify depression types; explain how depressions form; find elevation data; recognise hazards such as sinkholes and flooding.
Distinguishing features
Sunken landform
Many formation processes
Some below sea level
May collect water
What it looks like
Hollows, basins or low-lying areas, sometimes holding lakes or salt flats.
How it is recognised
Lower than surrounding land
Closed or open basins
Depression in mood or the economy is a different sense
