When the lower parts of a tree burn away and weaken the support for the rest of the tree so it falls, it is called a

Explanation:
The key idea is that the tree falls because its foundation—the root system and lower-support structure—has been damaged by fire. When the lower parts, especially the roots near the base, burn away, the tree loses its anchorage and can topple. That specific failure mode is called root failure. A snag is simply a standing dead tree, not describing the mechanism by which it falls. Crown break and branch failure refer to damage in the upper parts or limbs, not the base. So the scenario described aligns with root failure.
