地球的快速与缓慢变化
Fast & Slow Earth Changes
了解地球表面会发生变化：有些变化是快速的（如火山喷发、地震），有些变化是缓慢的（如风和水对岩石的侵蚀）。
Understand that Earth's surface changes: some changes are quick (eruptions, earthquakes) and some are slow (wind, water wearing away rock)
学习证据 / Evidence
- 举出一个地球表面快速变化的例子，比如火山喷发。
- 举出一个地球表面缓慢变化的例子，比如风或水的侵蚀。
- 比较快速变化和缓慢变化，并说明它们的不同之处。
- Give an example of a quick change to Earth's surface like a volcanic eruption
- Give an example of a slow change to Earth's surface like erosion by wind or water
- Compare quick and slow changes and explain the difference
评估问题 / Assessment
如果你指出一座悬崖正在被海浪渐渐侵蚀，{{name}}能解释出这是一个缓慢的过程，而火山喷发或地震则会快速地改变地貌吗？
If you point out a cliff being worn away by waves, can {{name}} explain that this happens slowly, while a volcanic eruption or earthquake changes the land quickly?
