How do plates move? Plates consist of two types of crust ….. The plates float ….. Heat from ….. convection currents Few centimetres each year. Plates may move in 3 directions …… Continental crust Oceanic crust
What have I learnt? Next lesson: constructive boundaries …. Why is the UK moving further away from USA?
Objectives of lesson today:

To copy level achieved and development targets from yr 8 reports onto target sheet in Ex books
Obtain coloured picture showing 4 layers of earth and stick in ex book
Learn glossary of key words: Continental plate, oceanic plate, crust, mantle, inner core, outer core, subduction zone, destructive plate boundary, convection currents, ocean trench to be found on the blog . http://tudorgeogclass2011.blogspot.com
