Summary
A Science lesson on plate tectonics — covering Earth's layers, what drives plate movement, and the three types of plate boundaries and the events they cause.
Student Worksheet: Plate Tectonics
Teacher Note: Students can watch the video lesson above and answer the questions. Click the “Teacher Answer Key” dropdown below when you are ready to review the solutions!
Key Concepts:
• Earth’s Layers: Crust, mantle, outer core, and inner core; the crust and upper mantle together form the rigid lithosphere.
• What Drives the Plates: Heat from inside Earth, plus forces called ridge push and slab pull.
• Divergent Boundaries: Plates pull apart, magma rises, creating new crust and volcanoes.
• Convergent Boundaries: Plates collide, causing mountains, deep earthquakes, and sometimes volcanoes.
• Transform Boundaries: Plates slide past each other, building stress that suddenly releases as earthquakes.
Instructions: Read each question carefully and write your answer in the space provided.
- Question 1: What are Earth’s four main layers?
- Question 2: What is the lithosphere made of?
- Question 3: Name the two forces mentioned that help drive plate movement, besides heat.
- Question 4: What happens at a divergent boundary?
- Question 5: What happens at a convergent boundary?
- Question 6: What happens at a transform boundary, and what real-world event does this describe?

1. Crust, mantle, outer core, and inner core.
2. The crust and the upper mantle.
3. Ridge push and slab pull.
4. Plates pull apart, magma rises, creating volcanoes and new crust.
5. Plates collide, causing mountains, deep earthquakes, and sometimes volcanoes through subduction.
6. Plates slide past each other, building stress until rocks suddenly slip, causing an earthquake.

🎯 Extension Activity: Have students draw all three boundary types side by side with arrows showing plate direction, and label a real-world example for each (e.g., the San Andreas Fault for transform, the Mid-Atlantic Ridge for divergent).
