Is flooding and the destruction of a bridge likely to occur in the aftermath of a volcanic eruption in the Cascades Range? Explain.

Yes

Explanation:

the fast cooling lava from the volcano turns into (igneous rocks) and may somehow get to the bridge, Lava cools very quickly at first and forms a thin crust that insulates the interior of the lava flow ... Thick stacks of lava flows (30 m or 100 ft thick) can take years to cool completely. It also depends on the range between the volcano and bridge, the cascades range has a lot (a LOT) of volcanoes so most likely
