构造板块
Tectonic Plates
了解地球的地壳是由称为构造板块的巨大碎片组成的，这些板块漂浮在下方更热、更软的岩石上，并且移动得非常缓慢——每年仅移动几厘米。
Understand that Earth's crust is broken into large pieces called tectonic plates that float on hotter, softer rock beneath and move very slowly — a few centimetres per year
学习证据 / Evidence
- 将地球地壳描述为分裂成若干大板块
- 解释这些板块漂浮在下方较热的、部分熔融的岩石上
- 说明板块移动非常缓慢，通常每年只移动几厘米
- Describe Earth's crust as broken into large plates
- Explain that the plates float on hotter, partially melted rock underneath
- State that plates move very slowly, typically a few centimetres per year
评估问题 / Assessment
如果你给{{name}}看一张构造板块地图，他们能不能解释地球表面裂成巨大的板块，并且这些板块移动得非常缓慢——大约和他们的指甲生长速度一样快？
If you showed {{name}} a map of the tectonic plates, could they explain that Earth's surface is cracked into huge pieces that move very slowly — about as fast as their fingernails grow?
