Why are weather kites no longer used (much) operationally?
Earth ScienceAsked by: Rene Kielholz How are kites used for weather? Each kite train carried a meteorgraph, a combined instrument package which recorded temperature, wind velocity, humidity, and barometric pressure. While weather kites have been largely superseded, they still have their uses, and are still employed by the British Antarctic Survey. How did they predict the
What geological events could cause a Volcanic Explosivity Index (VEI) level 9 eruption?
Earth ScienceAsked by: Aaron Howell Is a VEI 9 eruption possible? It is possible that evidence for a VEI 9 eruption exists and is buried in the geologic record. Eruptions that large would be very rare events, but it is impossible to say that eruptions that large have never occurred. What is VEI what were the
Why the “Mission to Earth’s core” proposal suggests using liquid iron instead of lead?
Earth ScienceAsked by: Aaron Howell Why do scientists think the Earth’s core is liquid? Two kinds of waves created by earthquakes are compressional (P) waves and shear (S) waves. Both of these waves can travel through solids, but S waves cannot travel through liquids. Scientists figured out that the outer core must be liquid because S
Eruptive fissures in Hawaii associated with Kilauea; what are they? What is really happening?
Earth ScienceAsked by: Haydee Broomfield What happened during the eruption of Kīlauea? The eruption began on January 3, 1983, as the first of several fissures broke out on Kīlauea’s East Rift Zone. By June 1983, the eruption became focused at a single vent, and over the next 3 years, a series of 44 lava fountains built
Sedimentology (Particle size distribution parameters)
Earth ScienceAsked by: Haydee Broomfield How do you determine particle size distribution? Particle size distribution and size averages are determined by particle counting in a Coulter counter (e.g., Multisizer 3). It provides number, volume, mass, and surface area size distributions in one measurement, with an overall sizing range of 0.4 μm to 1,200 μm. What is
How is a weather forecast really done?
Earth ScienceAsked by: Robert Larjin Polar orbiting satellites provide the information most useful for long-term weather forecasting. These satellites use instruments to measure energy, called radiation, emitted by the Earth and atmosphere. This information is incorporated into weather models, which in turn leads to more accurate weather forecasts. How is weather forecasting done short answer? Weather
