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
What would happen if you hypothetically happened to touch an aurora
Earth ScienceAsked by: Robert Larjin What would happen if you touched an Aurora? The aurora is emitted between 90 and 150 km in altitude (i.e. mostly above the ‘official’ boundary of space, 100 km), so ungloving your hand inside an aurora would likely be fatal (unless a fellow astronaut immediately reattaches your glove and repressurizes your
What’s the contribution of different types of river sources?
Earth ScienceAsked by: Joseph Pratt Why is a river source important? Rivers are absolutely vital: for fresh drinking water, for people’s livelihoods and for nature. Unfortunately, they’re still threatened. We must commit to recovering freshwater biodiversity, restoring natural river flows and cleaning up polluted water for people and nature to thrive. What are the sources of
Why is colored seismic inversion called ‘colored’?
Earth ScienceAsked by: Joseph Pratt The earth’s reflectivity can be considered fractal, and the resulting amplitude spectrum favors high frequencies (spectral blueing). If there was no preferred frequency, then you would have a “white spectrum”, but as there are some frequencies with more energy, then it is called “colored”. What is Coloured inversion? Coloured Inversion is
