In 1980 Mount St. Helens in Washington state erupted. What were some of the destructive forces that occurred

The hot rocks and gas quickly melted some of the snow and ice capping the volcano, creating surges of water that eroded and mixed with loose rock debris to form volcanic mudflows (lahars). Several lahars poured down the volcano into river valleys, ripping trees from their roots and destroying roads and bridges.

Explanation:

Over a thousand feet of the top of the mountain was obliterated, causing darkness during the day  for towns up to 85 miles away, mudslides and large ask deposits, loss of life to humans and animals.

Explanation:

I took the k12 quiz and got it rightt

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
