2. Do Now Take all the papers out of your red folder. Take them home.

3. Write a paragraph using the words below. You may not use your book. landformsplate tectonics continental drift faultweathering erosiondeposition floodplaindelta

4. word splash A floodplain is plain that has been flooded. A landform is land that is in a different form. A delta is a narrow stream. Erosion is when a river slower wears down a landform.

5. Essential Question How do forces of the Earth cause geographic changes?

10. A. Plate Tectonics The theory that earth’s surface is divided into several major, slow-moving plates or pieces. 1. Layers of the Earth a. Crust b. Mantle c. Outer Core d. Inner Core 2. Pangaea a. The name given to Earth’s landmasses when it formed one huge supercontinent. 3. Continental Drift Theory a. Forces within earth caused Pangaea to break apart into continental plates and drift apart. 4. Mountain formation a. tectonic plates push together b. two plates collide and one moves up over the other

11. B. Earthquakes 1. Plates shake causing an earthquake 2. A fault is a break in Earth’s crust where movement occurs.

12. C. Volcanoes 1. Plates push against each other creating cracks in the crust onto Earth’s surface. 2. Heat within the mantle causes rock in the lower plate to melt. This molten rock is magma. 3. Lava is the name for magma that has escaped onto the surface.

13. Do Now Read page 23-24 Shaping Earth’s Surface silently.
