Eruptions are not centralized at the main summit as with other volcanic types, and often occur at vents around the summit and from fissure vents radiating out of the center. [4] Hawaiian eruptions often begin as a line of vent eruptions along a fissure vent, a so-called "curtain of fire." These die down as the lava begins to concentrate at a ...
A thunderegg (or thunder egg) is a nodule-like rock, similar to a filled geode, that is formed within rhyolitic volcanic ash layers. [1] Thundereggs are rough spheres , most about the size of a baseball —though they can range from a little more than a centimeter (one half inch) to over a meter (three feet) across.
This is possible in part because of the rapid rate of extrusion (over a cubic km per day per km of fissure length [16]) and the relatively low viscosity of basaltic lava. However, the lateral extent of individual flood basalt flows is astonishing even for so fluid a lava in such quantities. [ 35 ]
Hawaii's Big Island continues to be plagued by volcanic eruptions, which have destroyed several homes and forced roughly 2,000 people to evacuate.
Scientists have tried to use CAT scans to look for embryo fossils contained inside the egg without having to damage the egg itself by physically extracting them. However, as of Ken Carpenter's 1999 book on dinosaur eggs, Eggs, Nests, and Baby Dinosaurs, all alleged embryos discovered using this method were actually false alarms. Variations in ...
Ice eggs, or ice balls, are a rare phenomenon caused by a process in which small pieces of sea ice in open water are rolled over by wind and currents in freezing conditions and grow into spheroid pieces of ice. They may collect into heaps of balls or 'eggs' on beaches where they pack together in striking patterns.
