Scientific Fraud
Scientists faking their data affects all scientific research. Most experiments are based off of other experiments that have already been done and if there’s false data then it could change the conclusion of the tests and it could alter the results. If scientists didn’t “fudge” their data then there could be more cures for diseases. Technology could advance and new discoveries could be made. The counterargument to that statement, though, is that if scientists

Sea Caves
Sea Caves Sea caves are mostly formed near the coasts. The process by which sea caves occurs is where waves break directly on a rock cliff and essentially erosion occurs, causing the cliff to give way under the force of the waves. This leaves behind supporting pillars and arches. One of the largest concentrations of large sea caves is found on Santa Cruz Island in California (http://en.wikipedia.org/wiki/Cave).
