View Available Hints Reset Help thrust faults normal fauts wolcanoes producing mafi lavss volcances producing andesitic lavas Would be found at a divergent boundary Would NOT be found at a divergent boundaryExplanation / Answer
1) Thrust faults are formed when two tectonic plates under compressive forces overlaps each other, so they would not be found at divergent boundary and rather at convergent boundaries.
2) tensional stress produces normal faults. two tectonic plates moving away from each other often creates continental rift and sometimes down dropped valley.
so, it would be found at divergent boundaries .
3) volcanoes producing mafic lavas are found at the divergent boundaries.
with divergent plate boundary lava flows more freely than the andestic lava.
4) volcanoes producing andestic lava are located at the convergent boundary.
