3. 5th Grade Pangaea Question
Explain what Pangaea is and why it was part of Alfred Wegener’s theory.

4. 5th Grade Pangaea Answer
All continents were once connected in a large continent called Pangaea. Wegener suggested they broke apart and made today’s continents. Theory says all continents drifted apart and continue to do so.

5. 5th Grade Seafloor Spreading Question
What is seafloor spreading and how does it support the theory of continental drift?

6. 5th Grade Seafloor Spreading Answer
Happens at the ocean ridges; magma pushes through Earth’s crust and cools, forming new crust; then more magma pushes up and pushes the new and old crust aside
Rows of magnetism on the ocean floor show that rock has been spreading on the ocean floor

23. Million Dollar Question Grade Level Plate Tectonics

24. 1,000,000 Question
The theory of plate tectonics explains many of Earth’s features and how they happened. Describe how the theory of plate tectonics explains why most earthquakes occur near plate boundaries. Describe how the theory of plate tectonics explains why most volcanoes occur near plate boundaries.

25. 1,000,000 Answer
Plates get caught when they are sliding by each other; pressure builds until the pressure becomes too great; rocks suddenly move and cause an earthquake
One plate sinks below another at a boundary, the sinking crust melts to magma; when the crust cannot withstand the pressure; magma explodes as a volcano
