The "Mountain or Valley?" illusion makes our brains turn valleys inside out. But inside-out valleys are a real thing, both on Earth and on Mars.

If you want to learn more about this topic, start your googling with these keywords:
Inverted relief: a
topographic feature, such as an old riverbed, that has reversed its elevation relative to other features. Duricrust: a hard mineral crust formed at or near the surface of soil in semiarid regions by the evaporation of groundwater. Geomorphology: the study of the physical features of the surface of the earth and their relation to its geological structures. Exhumed paleochannel: a remnant of an inactive river or stream channel that has been either filled or buried by younger sediment, and then subsequently uncovered by erosion. Erosion: the action of surface processes,
including wind and water, that move dirt and rock from their original location to some other place. Capillary action: the tendency of a liquid in a capillary tube or absorbent material to rise or fall as a result of surface tension. Mineral precipitation: when dissolved compounds in a solution bond together to form a solid (a simple example is how dissolved sodium and chloride ions come together to form salt as water evaporates) ___________________________________________ Credits (and Twitter handles): Script Writers: David Goldenberg (@dgoldenberg) & Emily Elert
