### 2.2c convection currents drive the tectonics movement that drives vocanic activity

1. 1. VL = 1 Bellwork 1. Make a brief summary: a. How are earthquakes formed/made? b. What make volcanoes erupt?
2. 2. Convection Objective: how convection activity relates to plate movements and volcanoes.
3. 3. ConvectionVocabulary Viscous – (viscosity) resistance of fluids to flow. Viscosity of fluids depends on the “thin-nes” or “thickness” of a fluid.  Example:  Water is thin – its resistance to flow is low.  Honey is thicker – its resistance to flow is high.
4. 4. ConvectionVocabulary Rheids – are solid materials, like rocks, that deforms by viscous flow.  Example:  The earth’s mantle is made up of solid materials that are in semi-liquid form due to extreme heat, it behaves as a rheid.
5. 5. ConvectionVocabulary Convection - refers to the movement of molecules within fluids (i.e. liquids, gases and rheids). It is one of the major modes of heat transfer and mass transfer.
6. 6. Convection  Hotter molecules rise.  Cooler molecules go down.  Given the above facts, predict what is its effect in a pot of cold water on a hot plate.  Ans:  Heat is evenly distributed.  Matter is evenly distributed
7. 7. Convection  Hotter molecules rise.  Cooler molecules go down.  In a pot of boiling spaghetti sauce are chopped Italian sausages.  Predict its movement in the sauce.  Will the temperature of the ingredients be the same?  Will the sausages remain at the bottom?
8. 8.  Hotter Convection molecules rise up.  Cooler molecules go down.  Land heats up easily and cools down easily.  The sea heats Explain the convection activity in up slowly and the picture cools down slowly.
9. 9.  Hotter Convection molecules rise up.  Cooler molecules go down.  Land heats up easily and cools down easily.  The sea heats Explain how this convection up slowly and activity relates to plate cools down movements and volcanoes. slowly.
10. 10.  Hotter Convection molecules rise up.  Cooler molecules go down.  Land heats up easily and cools down easily.  The sea heats up slowly and Draw and label 1. cools down slowly.
11. 11.  Hotter Convection molecules rise up.  Cooler molecules go down.  Draw and Label 2 Explain how this convection activity relates to plate movements and volcanoes.
