1. Plate boundaries and their processes
By the end of today’s lesson all of you will:
Identify different plate boundaries using digital images and maps
Know the different plate boundaries and the features of them
Some of you will:
Explain what happens at plate boundaries
Key terms: Destructive, constructive, conservative and collision margins (boundaries) digital images, subduction, hot spots

2. Today I am looking for: Good observation skills
Good descriptive and analysis skills
Good collaberation skills
Good leadership skills

3. What is happening at these plate boundaries in relation to convection currents kinesthetic RISING FALLING point and name boundary pupils to to the correct poster
Conservative margin

4. Animations Destructive plate boundaries/ margins
Constructive plate boundaries / margins
Collision plate boundaries / margins
Conservative plate boundaries / margins
Hot spots
Use the animations to help pupils understand concept - use digital images to show actual margin

5. Q & A Each student needs copy fig 5 in separate word doc, Next four slides get students using digital images to recognise features, Identify which type of boundary slide 1 – Constructive and name plates????? MID ATLANTIC RIDGE
Students to have a copy of fig5 ( there is a word doc in file with it on) for this lesson glue into books to refer to when needed

6. Conservative SAN ANDREAS FAULT Plates????

7. Collision Boundary Himalayas Plates????

8. Destructive ANDES point out the trench dark line Plates??????

9. 1. Describe the distribution of plate boundaries. (3 marks)
2.Identify the type of boundary or boundaries found between the
The African plate and the Eurasian plate
The indo Australian plate to the East of India and the Eurasian plate
The Eurasian plate and the North American plate
( 3marks)

10. Answer – swap books – Peer assess
1) Very uneven. Two basic categories – close to continents (1 mark)or mid-ocean (1 mark). There are a few exceptions, as with the Eurasian/Indo-Australian boundary(1 mark).
2) (a) A destructive boundary/margin.( 1mark) (b) A collision plate boundary/margin.(1 mark) (c) A constructive boundary/margin.(1 mark)
Total 6 marks

11. Group work Into groups and using the processes grid:
Elect one member to be “teacher”
When asked “teacher” move around to next group and teach the information
By the end all columns should be completed

12. Type of margin / boundary Processes Main features Example
Destructive plate boundary/ margin
Oceanic crust destroyed
Oceanic plate subducts under less dense continental plate forming fold mountains in the process
Magma rises through weaknesses melting crust forming volcanoes
Frequent earthquakes and volcanoes
~Ocean trench
Fold mountains
Nazca and South American plates
Use FOLLOWING SLIDES TO SELF ASSESS THE PROCESS GRID

13. Type of margin / boundary
Processes
Main features
Example
Constructive plate boundary/ margin
New basaltic material rises to the surface forcing oceanic plates
Hot magma is able to fill the “gap” creating new crust.
As magma continues to build up new mountain ranges form under sea = mid-ocean ridge
Magma continues to rise until eventually above sea = volcanic island
New crust created
Mid Ocean ridges
Volcanoes
Earthquakes
Mid Atlantic ridge between the Eurasian and North Amercian plates
Volcanic islands Surtsey and Iceland

14. Type of margin / boundary
Processes
Main features
Example
Collision Plate boundaries/margins
Two continental plates moving towards each other
Same density so no subduction crusts buckle and fold = no volcanoes
Crust neither formed or destroyed
Fold mountains
Earthquakes common
Himalayan mountain chain
Tibetan plateau
Pakistan earthquake 2005

15. Type of margin / boundary
Process
Main features/processes
Example
Conservative plate boundaries/margins
Plates slide past each other = Crust neither created or destroyed because no magma or subduction
Friction between plates = extreme stress builds in crustal rocks when released = earhtquake
Longer period of movement = more stress build up so when released = more energy significant earthquake
Earthquakes
San Andreas fault- North American and Pacific plates (same direction slip)
