Plate Tectonics & Evolution
| Question | Answer |
|---|---|
| species | A group of similar organisms that can mate with each other and produce offspring that can also mate and reproduce |
| fossil | The preserved remains or traces of an organism that lived in the past |
| adaptation | An inherited behavior of physical characteristic that helps an organism survive and reproduce in its environment |
| evolution | Change over time; the process by which modern organisms have descended from ancient organisms |
| natural selection | The process by which organisms that are best adapted to their environment are most likely to survive and reproduce |
| variation | Any difference between individuals of the same species |
| Plate | A section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of continental and oceanic crusts |
| Plate tectonics | The theory that pieces of Earth's crust are in constant motion, driven by convection currents in the mantle |
| Fault | A break in Earth's crust where masses of rock slip past each other |
| Divergent boundary | A plate boundary where two plates move away from each other |
| Convergent boundary | A plate boundary where two plates moves towards each other |
| Transform boundary | A plate boundary where two plates move past each other in opposite directions |
| Ring of Fire | Area the circles the Pacific Ocean where we find larger number of volcanoes and earthquakes. |
