监测火山
Monitoring Volcanoes
了解火山学家如何通过寻找警示信号——气体排放、地面隆起、小地震——来监测火山，并理解火山预测基于证据且存在不确定性，而非确定性。
Understand how volcanologists monitor volcanoes by looking for warning signs — gas emissions, ground swelling, small earthquakes — and that prediction involves evidence and uncertainty, not certainty
学习证据 / Evidence
- 说出科学家在火山喷发前会观察的至少两个警示信号
- 解释火山学家如何综合多种证据来评估喷发风险
- 讨论为什么火山预测存在不确定性，无法保证准确的时间
- Name at least two warning signs scientists look for before an eruption
- Explain that volcanologists combine multiple types of evidence to assess risk
- Discuss why volcanic prediction involves uncertainty and cannot guarantee exact timing

{{name}}能解释科学家如何留意火山可能喷发的迹象——比如气体、地面隆起或小地震——以及为什么他们能向人们发出警告，却无法预测确切的时间吗？
Can {{name}} explain how scientists watch for signs that a volcano might erupt — like gas, ground bulging, or tiny earthquakes — and why they can warn people but can't predict the exact moment?
