Question

read the paragraph. known for its unusually vivid blue color, crater lake is the deepest lake in the united states. crater lake was formed more than 7,000 years ago when the volcanic peak mount mazama erupted. the massive eruption ejected so much material from the interior of mount mazama that it destabilized the mountain. as a result, the peak collapsed and a large caldera, or crater, formed. rocks and ash from the eruption filled part of the caldera and, over time, rain and melted snow accumulated in the caldera to create crater lake. this question has two parts. answer part a, and then answer part b. part a what does the word destabilized mean in the paragraph? 1. covered 2. heated 3. soaked 4. weakened part b which detail from the paragraph best supports the correct answer from part a? 1. \deepest lake in the united states\ 2. \ejected so much material\ 3. \the peak collapsed\ 4.
ain and melted snow accumulated\

Explanation:

For Part A, when a large - amount of material is ejected from a mountain's interior, it makes the mountain less stable or weakens it, so "weakened" is the correct meaning of "destabilized". For Part B, the fact that "the peak collapsed" shows that the mountain was weakened (destabilized) by the eruption.

Answer:

Part A: 4. weakened
Part B: 3. "the peak collapsed"
