Chert
Chert is widespread, but not widely known by the public as a distinct
rock type. Chert has four diagnostic features: the waxy luster, a
conchoidal (shell-shaped) fracture of the silica mineral chalcedony that
composes it, a hardness of seven on the Mohs scale, and a smooth
(non-clastic) sedimentary texture. Many types of chert fit into this
categorization. (ThoughtCo.)

study. And those hypoxic conditions, which are expected to become common
with global warming, threaten the food web, the study found. The study
from Oregon State University, published in Nature Scientific Reports,
used data from 2021 to map out oxygen levels across the bottom 32 feet
of the Pacific Northwest continental shelf. Amanda Zhou reports. (Seattle Times)
