4 5th Grade Pangaea Question / Explain what Pangaea is and why it was part of Alfred Wegener’s theory.

5 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. Return

6 5th Grade Seafloor Spreading Question / What is seafloor spreading and how does it support the theory of continental drift?

7 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 / 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 Return

8 4th Grade Earth Question / Where is most of Earth’s mass located?

9 4th Grade Earth Answer / In the mantle. Return

10 4th Grade Seismographs Question / What do seismographs detect?

11 4th Grade Seismographs Answer / Ground movement as it occurs. Return

12 3rd Grade Earthquakes Question / Why do most earthquakes in the US occur in California and Alaska?

13 3rd Grade Earthquakes Answer / These states are located on a plate boundary. Return

14 3rd Grade Volcanoes Question / Where are most volcanoes located?

15 3rd Grade Volcanoes Answer / The ocean floor.

16 2nd Grade Earth's Layers Question / Earth’s inner core is a ________ _________ _________.

17 2nd Grade Earth's Layers Answer / Very dense solid. Return

18 2nd Grade Earth's Layers Question / Earth’s crust and the solid part of the mantle make up the ____________.

19 2nd Grade Earth's Layers Answer / Lithosphere Return

20 1st Grade Landforms Question / Which landform can be described as an area of flat land with few trees?

21 1st Grade Landforms Answer / Plateau. Return

22 1st Grade Plate Tectonics Question / Where are Earth’s tectonic plates found?

23 1st Grade Plate Tectonics Answer / On top of the lower (inner) mantle. Return

24 Million Dollar Question Grade Level Plate Tectonics

25 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.

26 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 / 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 Return
