岩石类型
Types of rocks
运用关于地球地质过程和岩石类型的词汇——火成岩、沉积岩、变质岩、侵蚀、风化、沉积、化石、沉积物、地层、透水性、不透水性——来解释岩石如何形成，以及地貌如何随时间变化。
Use vocabulary for Earth's geological processes and rock types — igneous, sedimentary, metamorphic, erosion, weathering, deposition, fossil, sediment, strata, permeable, impermeable — and apply these when explaining how rocks form and how landscapes change over time
学习证据 / Evidence
- 正确区分火成岩、沉积岩和变质岩，并用一句话说明每种岩石是如何形成的。
- 将“侵蚀”“风化”和“沉积”作为三个不同阶段，按正确顺序使用。
- 使用“沉积物”和“沉积岩”正确解释化石是如何形成的。
- Correctly classify igneous, sedimentary, and metamorphic rocks and explain in one sentence how each type forms
- Use 'erosion', 'weathering', and 'deposition' correctly as three distinct stages in a sequence
- Explain how fossils form using 'sediment' and 'sedimentary rock' correctly
评估问题 / Assessment
{{name}}能否解释一下岩石的风化和侵蚀有什么区别——这两者其实是不同的概念？
Could {{name}} explain the difference between a rock being weathered and being eroded — those are actually two different things?
