Instructions
Read each section carefully and complete the tasks. Use your knowledge of plate tectonics to draw the diagrams and fill in the chart.
3. Diagram Drawing
In the boxes below, draw and label the two types of plate boundaries described. Be sure to include arrows to show the direction of plate movement and label key features like plates, magma, and any landforms created.
Convergent Boundary (Plates Colliding)
Divergent Boundary (Plates Moving Apart)
4. Cause & Effect Chart
Complete the chart below by filling in the "Effect" of each plate movement. Then, provide at least one real-world example for each row.
| Cause | Effect (What happens?) | Real-World Example |
|---|---|---|
| Plates are constantly moving. | ||
| Two plates collide (convergent boundary). | ||
| Two plates slide past each other (transform boundary). |
Answer Key
3. Diagram Drawing
-
Convergent Boundary Drawing: The drawing should show two tectonic plates moving towards each other (indicated by arrows).
- One plate should be shown sliding underneath the other (this is called subduction).
- Labels should include: Tectonic Plates, Mantle, Subduction Zone, Magma (rising from the melting plate), and features like a Volcano or Mountain Range on the overriding plate.
-
Divergent Boundary Drawing: The drawing should show two tectonic plates moving away from each other (indicated by arrows).
- Magma should be shown rising up from the mantle to fill the gap between the plates.
- This process creates new crust.
- Labels should include: Tectonic Plates, Mantle, Magma, and a Mid-Ocean Ridge (a mountain range formed by the new crust).
4. Cause & Effect Chart
| Cause | Effect (What happens?) | Real-World Example |
|---|---|---|
| Plates are constantly moving. | Stress builds up in the crust, leading to earthquakes. | The 1906 San Francisco earthquake. |
| Two plates collide (convergent boundary). | Mountain ranges form, volcanoes erupt, or deep ocean trenches are created. | The Himalayan Mountains, Mount Fuji, Mariana Trench. |
| Two plates slide past each other (transform boundary). | Earthquakes occur along fault lines. | The San Andreas Fault in California. |
