" ... Other models are developed to explain the world. They provide cause and effect. For example, geologists and geophysicists have developed a plate tectonic model of the earth that explains the occurrence of earthquakes and volcanoes. However, the plate tectonic model can’t predict when major earthquakes or volcanoes will occur. Likewise, evolution is a model that explains the change of species over time but it cannot predict how a species will change in the future. ... "
" ... Through this process, scientists are able to measure the time it takes for many pulses of sound in a 3-D array to travel down and bounce back to the receiver. Merging this data, geophysicists are able to create an image of the subsurface in terms of time measured for the sound to travel down and bounce back. Geologists can then input the expected types of material the sound has travelled through to create a model that converts time to depth. Finally, you have a 3-D seismic depth map of the subsurface. ... "
" ... Vintage film of airborne radar surveys from the 1970s are helping modern geophysicists understand how ice sheets flow and how seawater erodes the ice from below. Equipped with the vintage data alongside modern images, computer models suggest that the Thwaites Glacier in West Antarctica is melting away even faster than anyone realized. ... "
