Tectonics Boundaries – Convergent
Open the digital learning object called ‘Tectonic Boundary – Convergent’ and as
you step through it, answer the following questions.
1. What type of tectonic plate boundary is found where the Nazca plate meets the
South American plate? (i.e. name the boundary type)
______________________________________________________________
2. What type of crustal material is present in the (i.e. oceanic or continental):
(a) Nazca plate: _________________________
(b) South American plate: __________________________
3. Describe what is happening at a convergent boundary.
______________________________________________________________
______________________________________________________________
4. What is the approximate rate at which these two plates are moving towards each
other each year?
____________________________
5. What is the term for the movement of the oceanic crust beneath the continental
crust?
____________________________
6. Describe what happens to the oceanic crust that is subducted.
______________________________________________________________
7. What forms on the continental crust adjacent to a subduction zone?

8. Name the geological events that may be associated with movements at this type
of tectonic plate boundary.

9. Explain how earthquakes are formed.

10. Draw and label a side-view diagram showing this oceanic-continental plate
convergence between the Nazca and the South American plates. Then, using
plasticine, toothpicks and labels, and the hints provided to you below, create a
labelled model of this boundary type. You may like to photograph it and put it in
your science journal.
Hints to help you build your plate boundary model:
blue plasticine = oceanic plate,
green plasticine = continental plate,
red plasticine = magma
arrows engraved in the plasticine plates = direction of movement of the plates
labels = for title of your model – i.e. Convergent Boundary – oceanic-continental
plate (perhaps you could use question 2 to name each of the plates)

11. Predict what feature forms when continental crust collides with continental
crust.
______________________________________________________________
The most famous example of this is the _______________________________
12. Which two plates collide to form these mountains?

13. Draw and label a side-view diagram showing this continental-continental plate
convergence between these two plates. Then, using plasticine, toothpicks and labels,
and the hints provided to you below, create a labelled model of this boundary type.
You may like to photograph it and put it in your science journal.
Hints to help you build your plate boundary model:
green plasticine = continental plate,
arrows engraved in the plasticine plates = direction of movement of the plates
labels = for title of your model – i.e. Convergent Boundary – continental-continental
plate (perhaps you could use answers to questions 11 and 12 to name each of the plates
and the featured event that happens at this boundary type)

14. What geological structure is found on the oceanic side of a convergent
boundary?

15. Draw and label a side-view diagram of an oceanic-oceanic plate convergence
between the Pacific plate and the Australian plate. Then, using plasticine,
toothpicks and labels, and the hints provided to you below, create a labelled model
of this boundary type. You may like to photograph it and put it in your science
journal.
Hints to help you build your plate boundary model:
blue plasticine = oceanic plate,
arrows engraved in the plasticine plates = direction of movement of the plates
labels = for title of your model – i.e. Convergent Boundary – oceanic-oceanic plate
(perhaps you could create and label the geographic structure from question 14)
