🌍 Part 1: Types of Plate Boundaries

1. Circle the THREE main types of plate boundaries:

Divergent

Convergent

Transform

Subduction

Volcanic

2. What happens at a divergent plate boundary?

Plates move towards each other

Plates move away from each other

Plates slide past each other

Plates remain stationary

3. Fill in the blanks about plate boundaries:

At _____________ boundaries, plates collide and one may slide under another. At _____________ boundaries, plates move apart creating new crust. At _____________ boundaries, plates slide horizontally past each other.

🌋 Part 2: Continental-Oceanic Convergence

4. Draw and label a diagram showing continental-oceanic convergence. Include these features: oceanic crust, continental crust, subduction zone, volcanic arc, trench

5. What is subduction?

6. Why do volcanoes form near ocean trenches in convergent boundaries?

7. Which type of crust is denser and why does it subduct?

Continental crust - it is thicker

Oceanic crust - it is denser

Continental crust - it is older

Oceanic crust - it is lighter

🇵🇭 Part 3: Philippine Examples

8. Match the Philippine geological features with their descriptions:

1. Philippine Trench

2. Ring of Fire

3. Mount Mayon

4. Subduction Zone

A. Active volcano in Albay

B. Deep ocean trench east of Philippines

C. Area where oceanic plate slides under continental plate

D. Zone of volcanic activity around Pacific Ocean

9. Why is the Philippines prone to volcanic eruptions and earthquakes?

10. Name TWO active volcanoes in the Philippines and their locations:

Volcano 1: _________________ Location: _________________

Volcano 2: _________________ Location: _________________

🔬 Part 4: Understanding Geological Processes

11. List THREE geological features that form at continental-oceanic convergent boundaries:

12. True or False - Circle the correct answers:

True / False - Earthquakes only occur at transform boundaries

True / False - The Philippine Trench was formed by subduction

True / False - Continental crust is denser than oceanic crust

True / False - Volcanic arcs form on the continental side of subduction zones

13. Explain why understanding plate boundaries is important for communities in the Philippines:

14. What safety measures should people living near active volcanoes take?

Have an evacuation plan

Monitor volcanic activity warnings

Keep emergency supplies ready

Ignore government warnings

Stay informed about geological hazards
