ocean topography
| Question | Answer |
|---|---|
| flat ocean bottom; flattest place on Earth | abyssal plain |
| weathered & eroded seamount | guyot |
| marks the true edge of a continent | continental slope |
| mountain range formed at oceanic divergent boundaries | midocean ridge |
| volcanic mountain formed on the ocean floor | seamount |
| V-shaped canyon that cuts through the continental shelf and/or continental slope | submarine canyon |
| slopes gently from the continental landmass; usually no deeper than 150m | continental shelf |
| deepest part of the ocean; very steep-sided; forms at convergent boundaries | deep ocean trench |
| topographical features of the ocean floor formed by plate tectonics | midocean ridge, rift valley, deep ocean trench |
| the ocean floor is predominately this feature | abyssal plain |
| mountain on the ocean floor NOT found at a plate boundary | seamount |
| depth increases faster at a (CHOOSE ONE): continental shelf / continental slope | continental slope |
| deep canyon on the ocean floor NOT found at a plate boundary | submarine canyon |
| valley between the ridges of the midocean ridge; formed where plates diverge | rift valley |
