1. Interaction Of Elements and Natural Processes
Operating in the Tongariro Volcanic Centre

2. Definition Involves elements of an environment being linked together.
Interaction incorporates movement, flows, connections, links and interrelationships. Landscapes are the visible outcome of interactions. Interaction can bring about environmental change.
What is an example of interaction in this classroom? What change does it bring about?

3. Elements vs. Processes
What is an element? A part, thing, or component of the environment
What is a process? A series of actions that shape or change the environment
Therefore: Vegetation is a _________________
But vegetation succession is a ______________
Element
Process

4. Warm up Task
Using the images below, write a sentence about how the following elements interact:
Soil interacts with vegetation because the more soil there is, the more vegetation can grow. Also, the more vegetation there is, the more wind-blown particles are trapped, and leaves/debris are dropped – which creates soil.

5. 3 September
LO) To be able to explain the interaction of elements in the TVC
SC) You can explain how 2 elements interact differently in different places
DN) Turn to the person next to you and tell them what Orographic Rainfall is
How does this relate to the TVC?

6. OROGRAPHIC RAINFALL in the TVC
Peaks, eg Ruapehu at 2797m
This can help you explain a spatial variation
TASMAN SEA
South-west slopes of Ruapehu
Rangipo Desert on the East

7. Warm up Task Climate Vegetation
Using the images below, write a sentence about how the following elements interact:
Climate
Vegetation

8. Task | Elements Diagram
Text Box Shuffle task to create an interaction diagram
The template has the arrows and the elements
Rearrange the textboxes to create a correct diagram
Open up the text box shuffle PPT in:
S:\Social Science\2. Geography\GEO 201\TVC
Rearrange the text boxes to fit with the diagram

9. Interaction Diagram Relief Soil Vegetation Climate LOCATION: TVC
Steep relief means less soil = less vegetation
The more erosive the weather, the less soil there will be
Vegetation traps windblown particles, and drops leaves to create soil
The colder the climate the less and the smaller the vegetation
The higher the elevation the colder the climate
Soil
Vegetation
Vegetation can slow down wind, reducing it’s effects
Weather elements erode relief features
The more fertile the soil, the better the vegetation
Steep relief = less soil because it runs off and erodes more
TIP: Rotate the textboxes so they are parallel to the arrow direction
Feel free to add your own..

16. Quiz Task
Person A turn to Person B and ask them to explain how any given 2 elements interact
Person B provide an answer and then do the same thing back at them
After 2 rounds each, start trying to ‘catch each other out’ by throwing in tricky questions

17. Spatial Variation of Interaction
Now go back to your interaction diagram and duplicate the slide 3 times (or copy + paste)
Give each of the new slides the following titles:
a. Bolderfield on Ruapehu, b. Beech Forest on Southwest slopes, c. Rangipo Desert (East)
Now adjust the thickness of the arrows depending on how strong you think the link is
For example: Beech Forest on SW Slopes:
VEGETATION CLIMATE

18. 4 September LO) To be able to summarise data into a table
SC) You can complete a summary table of data
DN) Take 5 minutes to finish your series of 3 interaction diagrams from last lesson (ppt)
DNX) Open up the Vegetation and Climate Interaction Summary Table PPT in the S: Folder

19. Different Locations in TVC
Rangipo Desert
Boulderfield
Beech Forest

20. 5 September
LO) To be able to explain the interaction of elements in the TVC
SC) You can explain how 2 elements interact differently in different places as SEXY paragraph/s
DN) Login to Kahoot.it ready for a quiz…

21. Spatial Variation
Things occur differently in different places, thus creating Spatial Variation.
This creates Patterns
This means interactions may be stronger or weaker in different parts of the TVC
Think about this as you answer the following questions in full sentences

22. Spatial Variation
Climate interacts with relief by eroding the land – where in TVC would this occur most?
Where would it occur the least? Why?
How does the interaction between climate and soil look on the Eastern slopes?
How does it look on the Western slopes?
EXTRA: Write your own question! Then give it to a buddy to answer

23. Paragraph Exemplars So what does this answer actually look like?
You will have 2 exemplars come up on your screen.
You must ‘grade them’ based on the marking schedule in front of you. There is an A and E
You are looking to see if the student:
Explain how the characteristics interact
Explain how the interaction varies in different parts of the environment (in our case, the TVC)
Include specific evidence (eg rainfall data from notes)

24. Paragraph Answer Writing
Putting all the pieces together
Use the following sentence starters to write a full paragraph answer on interaction between 2 elements.
Be sure to:
Explain how the characteristics interact
Explain how the interaction varies in different parts of the environment (in our case, the TVC)
Include specific evidence (eg rainfall data from notes)

25. How to Write it Typed up on either:
Word and ed to me
Google Doc and shared with me
You Must have a completed paragraph response to me by the end of the weekend –
no exceptions, no extensions

26. INTERACTION Sentence Starters
The elements of climate and ___________ are key features of the TVC, and interact in different ways in different parts of the environment
In this environment, the prevailing weather is from the West with evaporation occurring over the Tasman Sea and precipitation occurring mainly on the ________________, which receives ________ of rainfall per year.
This creates a spatial pattern of ______________ where _____________________because as …...
This can be contrasted to the Eastern slopes of ____________, where the rain shadow effect can be observed. This means that the climate is _____________________, exemplified by a rainfall of only ______________. This creates……
