板块边界

解释板块边界如何引发地震和火山：板块相互挤压、彼此分离或相互滑动错开时，会产生触发这些事件的力量；板块碰撞的地方则会形成山脉。

Explain how plate boundaries cause earthquakes and volcanoes: plates pushing together, pulling apart, or sliding past each other create the forces that trigger these events, and mountains form where plates collide

学习证据 / Evidence

• 描述三种板块边界的运动方式：汇聚型、分离型和转换型。
• 解释地震发生在板块于边界处相互摩擦或碰撞时。
• 解释火山形成于板块分离或一个板块滑到另一个板块下方、使岩浆得以上升的地方。

• Describe three types of plate boundary movement: convergent, divergent, and transform
• Explain that earthquakes occur when plates grind or collide at boundaries
• Explain that volcanoes form where plates pull apart or one slides under another, allowing magma to rise
