Two technological advances that have made it possible for scientists to better understand the dynamics of the Earth’s mantle are seismic snapshots and computer modeling. Seismic snapshots enable scientists to determine the temperature and density of the mantle. When an earthquake occurs vibrations are put into motion which create waves that can be detected by apparatuses, seismic waves. Using the instruments that are set up around the world, Geologists and Geophysics determine the amount of time it takes for the seismic wave to travel from the epicenter of an earthquake to a particular station, enabling them to …show more content…
Climate and erosion both contribute to the shape of landscapes by making certain process occur. For example, the local climate of an area affects which type of erosion that a mountain will experience. When there is a wetter climate, the erosion rates are faster; However the increase in moister yields more vegetation on the mountain which acts as a barrier to erosion. When a mountain is located in a dry area, the erosion rates are slower than those of wet climates. There is also little to no vegetation to serve as a shield to the surface of the mountain, making it erode faster. In addition, mountains that experience windy climates tend to erode more steadily than mountains in calmer climates. This is because the winds that flow over the mountains create more rain, which in turn, creates more erosion. The elevation of a mountain also effects the amount of erosion that it experiences. The higher the mountain is the lower the temperature becomes, making it difficult for vegetation to grow. The absence of vegetation makes the peeks of mountains more suitable to erosion. 4. What are some of the points that argue in favor of the view that intensified mountain building over the last 40 million years has caused the climate to cool? Conversely, what points argue that it was global cooling that caused the intensification of mountain building? (This is the "chicken and egg" question discussed in the
