  1. Geology

    Geology is the science comprising the study of solid Earth, the rocks of which it is composed, and the processes by which they change. Geology can also refer generally to the study of the solid features of any celestial body. Geology gives insight into the history of the Earth, as it provides the primary evidence for plate tectonics, the evolutionary history of life, and past climates. In modern times, geology is commercially important for mineral and hydrocarbon exploration and exploitation and for evaluating water resources. It is publicly important for the prediction and understanding of natural hazards, the remediation of environmental problems, and for providing insights into past climate change. Geology plays a role in geotechnical engineering and is a major academic discipline.

  2. Tanguy Bertrand:

    This discovery teaches us that there are still plenty of physical and dynamical processes out there in space that we do not know about, and that climates can be very different than that of Earth( despite forming a similar landscape), it is important to study Pluto and other planetary bodies because they are natural laboratories to explore and investigate the diversity of possible climates( and geology, and other planetary sciences) which gives us more perspective on our own climate.

  3. Steve Brusatte:

    The reason why the site is so important is that these footprints were made in a lagoon. We know from the geology this was a lagoon, sauropods were making their foot prints while they were wading in the water … We have three different layers so that is three different time intervals. This is telling us these huge dinosaurs lived or at least moved through these lagoons fairly regularly over time. This was a normal part of their repertoire.
