Types of Plate Boundaries

Three types of plate boundaries

---

Know: the different types of Boundaries and exhibited movement.

PLATE BOUNDARIES

• Convergent Plate
• Divergent
• Transform Fault

Divergent Plate

plates move apart, creating a zone of tension

Convergent Plate

moving toward each other, plates collide. Philippine plate & Eurasian plate.

Transform Fault

plates slide or grind past each other without diverging or converging. San Andreas fault bounded by North American & Pacific plate.

Activities!

Let's proceed!

Plate Boundaries

Activity 2: Let's Mark the Boundaries!

Objectives

---

• Describe the distribution of active volcanoes, earthquake epicenters, and major mountain belts.

• Determine the scientific basis for dividing the Lithospheric plates.

Activity 2: Let's Mark the Boundaries!

Materials

---

• Figure 5: Map of earthquake distribution

• Figure 6: Map of active volcanoes of the world

• Figure 7: Mountain ranges of the world

• marking pens (two different colors)

• Two pieces plastic sheet for book cover, same size as a book page

Procedures - PART A

Let's mark the boundaries!

---

• Study Figure 5 showing the earthquake distribution around the world.

• Trace the approximate locations of several earthquake “clusters” using a marking pen on one of the plastic sheets.

GUIDE QUESTIONS

Q5. How are earthquakes distributed on the map

?

GUIDE QUESTIONS

Q8. Where are they located

?

GUIDE QUESTIONS

Q7. Where are there no earthquakes

?

GUIDE QUESTIONS

Q8. Why is it important for us to identify areas which are prone to earthquakes

?

Procedures - PART B

Let's mark the boundaries!

---

• Study the map of active volcanoes in Figure 6.

GUIDE QUESTIONS

• Q9. How are volcanoes distributed?

• Q10. Where are they located?

• Q11. Based on the map, mention a country that is unlikely to experience a volcanic eruption.

Procedures - PART C

Let's mark the boundaries!

---

• On the second plastic sheet, sketch the approximate locations of several volcanoes using a marking pen.

• Place the earthquake plastic sheet over the volcano plastic sheet.

• Compare the location of majority of earthquake epicenters with the location of volcanoes around the world

GUIDE QUESTIONS

• Q12. How will you relate the distribution of mountain ranges with the distribution of earthquake epicenters and volcanoes?

• Q13. What do you think is the basis of scientists in dividing Earth’s lithosphere into several plates?

Thank you!
