How do shield and composite volcanoes form?

Section	Detail
Key Ideas	Shield volcanoes occur at constructive plate boundaries and composite volcanoes occur at destructive plate margins. Features of a volcano include magma chamber, vent, crater and layers of rock (lava) and sometimes ash.
Terms	Shield volcano, composite volcano, magma chamber, vent, crater
Starter	Violent volcanoes clip – what makes volcanoes erupt and are they all the same?
Main	1.   TDIT 2.   Students use diagram below to mark 12 volcanoes (see list below) on world map and label if they are on destructive or constructive plate margins – then say if shield or composite. 3.   Students draw and label NT p13 C&D and add 2 examples of each, country and plate margin. 4.   Volcano photo quiz
Plenary	a.   What are shield volcanoes and what type of plate margin would you find them on? b.   What are composite volcanoes? Plate margin type? c.   Name 2 shield and 2 composite volcanoes. Describe their location.

How do people use an area of fold mountains?

Section	Detail
Key Ideas	People choose to live in areas of fold mountains for the advantages they bring. People adapt to living in these difficult environments.
Terms	Fold mountains, subsistence, terraces, irrigation, hydroelectric power (HEP), Andes
Starter	Clip of formation of fold mts below
Main	1.   TDIT. 2.   Label Andes, Alps, and Himalayas on world map. 3.   Fact file on the Andes Mountains NT p16 1. Using p9 & maps below. 4.   Farming: Watch clip below and use NT p14 to answer NT p16 2. 5.   Mining: Watch clip below and use NT p15 to answer NT p16 3 as questions. 6.   HEP: Watch clip below and use NT p15 to answer NT p16 4. 7.   Tourism: Watch 1st minute of linked clip below and use NT p15/16 and impacts of tourism table (below) to write a paragraph arguing the pros and cons of the Inca Trail.
Plenary	a.   Give 3 reasons people choose to live in fold mountains areas. b.   Give 3 difficulties that they may have to overcome. c.   Explain one way people have adapted to their environment.

How are fold mountains and ocean trenches formed?

Section	Detail
Key Ideas	Fold mountains occur at collision (a type of destructive margin) boundaries. Ocean trenches and fold mountains occur at destructive margins (where subduction is occurring).
Terms	Fold mountains, ocean trenches, landforms
Starter	Quiz
Main	1.   TDIT. 2.   Show presentation and then clip of collision margin and destructive margin. 3.   Students draw fold mountains onto a world map and label which are destructive and collision margins using NT p12 A, plus label Andes, Alps, Himalayas, Rockies, Mariana and Atacama trenches. 4.   Show collision clip again and students draw cross-section (profile) with labels (including key terms). Repeat for destructive margin possibly using simplified version of previous lessons diagram. 5.   Students draw NT p13 B.
Plenary	a.   What are fold mountains? b.   What are ocean trenches? c.   Name 2 fold mountain ranges and 2 ocean trenches.

What are the different types of plate boundary?

Section	Detail
Key Ideas	The 3 main types of plate boundary, destructive, contructive and conservative are all different. Examples of the boundaries are important to remember.
Terms	Convection currents, destructive margin, constructive margin, conservative margin, subduction, collision
Starter	Lava image – where is that happening? What makes it liquid? Convection currents animation
Main	1.   TDIT 2.   World map of tectonic plates 3.   Plates jigsaw 4.   Annotate plate margin cross-sections (below) using NT p10/11 D, E, F 5.   Add examples: ·         Destructive (subduction) = Nazca moving under South American – Andes Mts ·         Destructive (collision) = Indian towards Eurasian – Himalaya Mts ·         Constructive = Eurasian & North American away from each other - Mid Atlantic Ridge/Iceland ·         Conservative = Pacific & North American moving alongside each other – San Andreas Fault, California
Plenary	a.   How quickly do plates move? b.   Give an example of a conservative plate margin. c.   What happens at a destructive plate boundary? d.   How was Iceland formed?

Why is the earth's crust unstable?

Section	Detail
Key Ideas	The earth's crust is unstable, especially at plate boundaries. There are differences between oceanic and continental plates.
Terms	crust, plate, plate boundary/margin, mantle, convection currents
Starter	Apple. NT p8 A
Main	1.   TDIT. 2.   Students draw cross-section of earth and annotate with Key Terms. 3.   Pack of cards/plates simile. 4.   Students examine examples of basalt and granite for differences between oceanic and continental crust (physical and/or videos below). 5.   Students draw diagram NT p9 B 6.   NT p9 Qus 2b
Plenary	a.   What are the two types of plate called? b.   Give one difference between them. c.   What is the name for where plates meet? d.   What causes the plates to move?
