The study also found that extension can occur at the same far-field location without a hot region when the OP is young and thin or when the subducting plate (SP) is old with a high sinking velocity. Our models suggest that the EH mode is common, occurring in many c...
What are the Hawaiian Islands formed over? How are valleys formed by plate tectonics? How does subduction create volcanoes? How are shield volcanoes formed? Describe how a volcano is formed at a continental rift. How are glacial erratics formed? How was the Kilauea volcano created? How are gl...
Why is it that magmas in continental coastal range volcanoes are of intermediate composition? How did the ice age create rivers in North America? How were the Pamir Mountains formed? What are the steps in arc-continent mountain formation?

Like the northern and southern lights, STEVE is a glowing atmospheric phenomenon, but it looks slightly different from its undulating auroral counterparts. "These emissions appear as a narrow and distinct arc, are typically purple in color and often include a green picket-fence structure that ...
In rapids, where water is fast and turbulent, there is water mixing leading to fast cooling. Then, small ice particles called frazil ice are formed. Such ice easily sticks to objects. Often frazil ice can build up thick ice covers on stream bottoms, anchor ice that is. If the rapids are...
Stress anomalies can be temporal or spatial, but a temporal stress perturbation is needed if the rupture occurs over the same patch (e.g., in the case of true anti-repeaters). Most of these models concern volcanic and induced seismicity, driven by geophysical processes involving deformation, ...
Oceanic trenches, which are the deepest chasms in the ocean, are formed during the subduction of two tectonic plates – basically, when they collide and one slides under the other. However, the Weber Deep is a forearc basin, which is basically a depression located in front of the Banda arc...
Evaluating the composition of the mantle plume head linked to the 132 Ma Parana-Etendeka flood basalt event is difficult because of potential interaction of melts with the continental lithosphere (both crust and mantle), which overall has a geo- chemically enriched composition in comparison with ...
According to Stacker, Mesa Verde National Park is the seventh-oldest one in the U.S., but it is the oldest national park in Colorado. Laura Seaman // UnsplashNPS notes that while the Ancestral Pueblo people came to the area about 1,400 years ago, President Theodore Roosevelt designated Mes...
