No, they're rock solid!
The plural of geologist is geologists. As in "the geologists are studying the meteor sample".
geologists!!! ... "biologists" not "geologists"...
That would be a geologist? Or if you wanted a name: http://en.wikipedia.org/wiki/List_of_geologists
There are different types of geologists that study oil exploration, mineral exploration and mineral mining. There are also engineering geologists.
I'm so lonely. That dog is lonely! I'm not lonely..
Rocks are to geologists as stars are to astronomers.
Geologists don't use rocks, they study them.
