One word photo challenge: depth.

Depth is the other direction when falling.

Or to say it with Terry Pratchett:

“I’m not going to ride on a magic carpet!” he hissed. “I’m afraid of grounds.” “You mean heights,” said Conina. […] “I know what I mean! It’s the grounds that kill you!” (from the Discworld novel “Sourcery”)
