Biological and medical scientists study living organisms and their relationship to their environment. Surveying and mapping scientists measure and map the earth's surface.
Engineers usually work near major industrial and commercial centers, often at construction sites.
Biological and medical scientists usually work regular hours in offices, laboratories or hospitals. Geoscientists divide their time between the office, field and laboratory. Oceanographers may spend long periods at sea on research ships. Surveyors typically work a 40-hour week, much of it outdoors. Land surveyors and technicians engage in physical work, often exposed to the weather.
