What is the connotative meaning of the underlined word "volcanic"?
Geologists are not the only scientists who study volcanoes. A biologist might lead a volcanic life as well. Biologists and meteorologists are concerned with what happens on the earth’s surface after volcanic events. Biologists may be interested in how life adapts to volcanic activity and meteorologists in how the atmosphere and weather are affected by it.
