Final answer:
Tensional stresses predominate at divergent plate boundaries where tectonic plates are moving away from each other, a setting that differs from convergent and transform boundaries, and is not typically associated with the stable interiors of plates or meteorite impact sites.
Step-by-step explanation:
Tensional stresses, which involve the pulling apart of the Earth's crust, would predominate at divergent plate boundaries. This is where the tectonic plates are moving away from each other. At a divergent boundary, the lithosphere is thinned as it is stretched, leading to a reduction in pressure that can allow the mantle to melt, potentially creating magma. The geologic activities at divergent boundaries are in sharp contrast to those at convergent boundaries, where plates move toward each other and may cause compressional stresses.
At convergent plate boundaries, one plate subducts beneath another, leading to the formation of mountain ranges, deep ocean trenches, and volcanic activity. This type of boundary is associated with compressional stresses rather than tensional ones.
Transform boundaries occur when plates slide horizontally past each other. These can also lead to earthquakes, but they are not typically sites where tensional stresses are dominant. Finally, the stable interior of a tectonic plate and meteorite impact sites are not typically associated with tensional stresses from plate tectonics.
