|---|---|---|---|---|---|
| Alfred Wegener | The German scientists who in 1912 developed the theory of continental drift later to be known as plate tectonics.
🗑
|
||||
| Transform Boundary | A plate boundary where two plates slide horizontally past each other.
🗑
|
||||
| Divergent Boundary | A plate boundary where two plates move aways from each other.
🗑
|
||||
| Plate Tectonics | The theory that pieces of the Earth’s lithosphere are in constant motion, driven by convection currents in the mantle.
🗑
|
||||
| Sea-Floor Spreading | The process by which molten material adds new oceanic crust to the ocean floor.
🗑
|
||||
| Mid-Ocean Ridge | The undersea mountain chain where new ocean floor is produced by a divergent boundary.
🗑
|
||||
| Continental Drift | The hypothesis that the continents slowly move across the Earth’s surface developed by Alfred Wegener.
🗑
|
||||
| Convection | The transfer of heat by movements of a heated fluid.
🗑
|
||||
| Convection Current | The movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another. This happens in the mantle.
🗑
|
||||
| Deep Ocean Trench | Deep valleys along the ocean floor through which oceanic crust slowly sinks towards the mantle.
🗑
|
||||
| Fault | A break in the Earth’s crust where slabs of rock slip past each other.
🗑
|
||||
| Convergent Boundary | A plate boundary where two plates move towards each other.
🗑
|
||||
| Pangea | Hypothetical land area believed to have once connected nearly all of the Earth's land masses together.
🗑
|
||||
| Tsunami | A large ocean wave that is caused by sudden motion on the ocean floor. This sudden motion could be an earthquake, a powerful volcanic eruption, or an underwater landslide.
🗑
