Which metamorphic rocks are most likely to have formed at the highest temperatures and pressures?

Schist and gneiss

Explanation: The rocks that forms at the highest pressure and temperature condition are Schist and Gneiss, where Gneiss being the highest grade metamorphic rock.

Schist is mainly comprised of quartz, some feldspars and platy minerals such as biotite and muscovite and are foliated rocks with a distinct cleavage commonly known as the schistocity.

Gneiss is mostly composed of quartz, hornblende, feldspar and mica. It has a distinct alternating bands of light and dark colored minerals. The minerals in the darker band contains hornblende, mica and garnet. The lighter band contain minerals such as feldpar and quartz. This banding has a significant characteristic for defining a gneissic rock.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

fossil's are like over rated rocks like low key not gonna lie i don't get why we can't just call them old rocks like for real i mean i call my grandpa and grandma that smh
