#2 | In a convection current, the cooler, deser fluid does this | What is sink to the bottom? |
#3 | The transfer of energy through empty space | What is radiation? |
#4 | Who first proposed the theory of Continential drift? | Who is Alfred Wegener? |
#5 | This erupts through the valley of the mid-ocean ridge | What is molten material? |
#1 | Heat transfer by movement of fluid is called | What is convection? |
#2 | This is the boundary where 2 plates slip pass each other | What is a transfrom boundary? |
#3 | This is part of the mantle that can bend like plastic | What is the asthenosphere? |
#4 | The process that continually adds new material to the ocean floor | What is sea floor spreading? |
#5 | The supercontinent that began to break apart 225 million years ago | What is pangaea? |
#1 | Geologists study these waves to gather indirect evidence about the inner earth | What are sesmic waves? |
#2 | These are deep underwater canyons that the ocean floor can plunge into | What are deep ocean trenches? |

#4 | this theory that state that the pieces of the lithosphere are in constant but slow motion | What is the theory of plate tectonics? |
#5 | the oceanic crust is made of this type of rock | What is basalt? |
#1 | The 3 evidences that Wegner used for his theory of continental drift | What are matching landforms,similar fossils and evidence of climate change? |
#2 | The 3 evidences that Hess used for his theory of sea floor spreading | What are molten material on the sea floor(pillows), magnetic stripes, and the age of the rocks through drilling samples? |
#3 | Name the factors that set convection currents in motion | what is temperature differences, density difference and gravity? |
#4 | This is a boundary where 2 plates pull apart from each other | What is a divergent boundary? |
#5 | This is a boundary where 2 plates collide into each other | What is a convergent boundary? |
Final Question | |
What happens at the different kinds of convergent boundaries? | O-O denser sinks (subduction) O-C denser basalt sinks C-C mountains form |
