### Understanding Earth’s Movement: Tectonic Plates and Their Impact ###

Explore the dynamic nature of Earth's structure and learn why it is always changing. This lesson examines convection currents and tectonic plates, including convergent, divergent, and conservative margins. Understand where volcanoes and earthquakes occur globally, the reasons behind these geological phenomena, and how convection currents drive the movement of tectonic plates. Visual aids and diagrams will enhance comprehension of constructive and destructive margins, providing insight into Earth's internal processes. ###

  1. Why does the earth move? Key words: Convection currents Tectonic plates Convergent Divergent Fold mountains L/O: To understand why the earth’s structure is always changing To describe where volcanoes and earthquakes are found in the world and why http://www.youtube.com/watch?v=Cm5giPd5Uro http://www.youtube.com/watch?v=CtBXTvtFaCU&list=PLEAC4343D4E68CFAF

  2. http://www.youtube.com/watch?v=Q9j1xGaxYzY The Earth’s structure Why do they say the earth’s structure is like an apple?

  3. Which plate do you live on? Which plates border the plate where you live? Which plates are moving towards / away from your plate? Where do you think volcanoes and Earthquakes occur and why? Explain your answer!

  4. Why do the plates moves? B A How do convection currents make our earth move? – draw a diagram if needed! What is created at A and B and why? One is called a CONSTRUCTIVE margin and one is called a DESTRUCTIVE margin – which do you think is which and why?

  5. Converging, diverging and conservative plates Constructive / diverging margin Destructive / converging margin Conservative plate margin Collision Margin
