Intro to Environmental processes

1. Teacher NotesRemember the intentions of this unit are to;A) educate boys about natural process and thesocial affects of such disastersB) Equip them with the skills and endurance todo written book work, note taking and writeessays. These of which are essential skills insocial studies, senior geography and University.

2. Kete Kupu Prominent Process Environmental

3. So what is anenvironmental process? It is processes, actions, operations, and cycles that occur naturally in the environment without the intervention or aid of man. Natural disasters are a result of an or combination of significant environmental processes.

4. What do we already know? What are all the different environmental processes you know?

5. What are the mostprominent 3 in NZ?

6. +So what do we need to understand first? Tectonic plates and how they move

7. + Layers of the earth Earth is made up of many different layers The interior layers of the earths are spherical, like an onion. Layers of the Earth

8. + Layers of the earth

9. + Practical Create a model of the layers of the earth. Complete the layers of the earth work sheet.

10. + Tectonic plates (copy this in full) The worlds surface is made up of many tectonic plates. There are 8 main plates. When the plates move volcanoes, mountains, earthquakes, and tsunamis are formed. Each tectonic plate is alongside another plate like a puzzle. Where they meet are called boundaries. There are three types of boundaries they are called; convergent boundaries, divergent boundaries, and transform boundaries

11. + Tectonic Plates

12. + Plate movement (copy this in full) Tectonic plates can move in three ways; Convergent one moves under the other Convergent boundaries is when plates in the earth overlap, one goes under and the other rises over to form mountain ranges. An example of a mountain range is the Himalayas. Divergent - move away from each other Divergent Boundaries are locations where plates are moving away from one another. This occurs above rising currents. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it. Divergent boundaries mostly cause volcanoes Transform they move along side each other Transform Plate Boundaries are locations where two plates slide past one another. Most transform faults are found in the ocean basin and connect offsets in the mid-ocean ridges. San Andreas Fault is an example.

14. + convergent video

15. + subduction video

16. + Mix and match all the squares so they align with the titles Divergent Convergent Transform One moves under the they move along side move away from each other each other other

17. + ANSWERS Divergent Convergent Transform move away from each one moves under the they move along side other other each other

18. + The Ring of Fire (copy the first 2 points) The "Ring of Fire is boundary stretching from New Zealand, along the eastern edge of Asia, north across the Aleutian Islands of Alaska, and south along the coast of North and South America The Ring of Fire is composed over 75% of the worlds active and dormant volcanoes.Now complete the Ring of Fire worksheet- Fill the gaps- Remember to glue it in your book
