In Earth Sciences we study the nature and evolution of our planet. Geoscientists use their knowledge to increase our understanding of Earth processes and to discover resources which improve the quality of human life. However, the focus of Earth Sciences is still the rocks, whether they are found on the deep ocean floor, or on the highest mountain peaks. This means that field work is a major part of our activities. In the field we make observations, explore the subsurface using geophysics and drilling, collect samples and take measurements that will be analyzed in the laboratory. Today, leading Earth Science institutions have as complex an infrastructure as any in Chemistry, Physics, or Biotechnology, and indeed utilize the same research philosophy and research techniques.
