Natural Gas fields as power sources
Earth ScienceAsked by: Linda Young Can natural gas be used for power? The electric power sector uses natural gas to generate electricity and produce useful thermal output. In 2021, the electric power sector accounted for about 37% of total U.S. natural gas consumption, and natural gas was the source of about 32% of the U.S. electric

What processes produced the basalt columns of the Giant’s Causeway?
Earth ScienceAsked by: Ben Young The origin of Giant’s Causeway in Northern Ireland is shrouded in myth & legend. But how did these interlocking basalt columns really come to exist? The process is called columnar jointing. It happens when a layer of molten lava gradually cools by a loss of heat through its surface. What process

Is climate change a vicious circle?
Earth ScienceAsked by: Ben Young What discipline does climate change fall under? Climate Change is studied under the modern discipline of Environmental Science, which is a branch of Earth Sciences or Atmospheric Sciences and crosses many boundaries, incorporating a wide variety of methods and tools. Why are warming temperatures causing a vicious cycle that leads to

Reasons for choosing LES in stead of RANS models?
Earth ScienceAsked by: Angela Foster Why LES is better than RANS? Abstract. Large Eddy Simulation (LES) undeniably has the potential to provide more accurate and more reliable results than simulations based on the Reynolds-averaged Navier-Stokes (RANS) approach. However, LES entails a higher simulation complexity and a much higher computational cost. What is the difference between RANS

I just read news that Antarctica had set a new record high temperature, above 18 °C. How can this be the case if it is currently winter there?
Earth ScienceAsked by: Lacey Moreno What is the record high temperature in Antarctica? The recent extraordinary heatwave in Antarctica appears to have set a new World Record for the largest temperature excess above normal (+38.5 °C / +69.3 °F) ever measured at an established weather station. It “appears to have set a new World Record for
