Kary mullis, the developer of the polymerase chain reaction (pcr), said that he thought up the process while he let his mind wander during a drive. how is this an example of creativity in science? mullis created a scientific process by using only his imagination rather than by using prior knowledge. mullis was able to think his way to a conclusion rather than gather data. mullis developed and performed his process in the field instead of in the laboratory. mullis was able to imagine the outcome of carrying out a different process.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
