It was centered at a relatively shallow depth of 6.2 miles (10 kilometers).

The lack of light and moisture combined with the shallow depth of soil make growing conditions harsh.

Shallow depth allows divers into the bridge area, where there are numerous fossilised saké bottles.

A high numerical aperture (equivalent to a low f number) gives a very shallow depth of field.

The sandstone had a negative effect on farming because it underlay most of the available flat land at a very shallow depth.
