A certain species of larva uses methane to propel itself, and it is even possible that this mechanism is accelerating the release of gases into the atmosphere and magnifying global warming, scientists have discovered. The research demonstrates the negative role played by the larvae not just in global warming but also in disturbing the sedimentary layers at the bottom of lakes.
Earth science or geoscience is an all-embracing term for the fields of science related to the planet Earth. It can be considered to be a branch of planetary science, but with a much older history. There are both reductionist and holistic approaches to Earth sciences. The Earth sciences can include the study of geology, the lithosphere, and the large-scale structure of the Earth’s interior, as well as the atmosphere, hydrosphere, and biosphere. Typically, Earth scientists use tools from geography, physics, chemistry, biology, chronology, and mathematics to build a quantitative understanding of how the Earth system works and evolves.
