- Features of the Oceans
- Continental Shelf
- Although below sea level, the shelf is part of the continent
- Continental Slope
- steeper slope of the continental margin between the edge of the shelf and where it merges into the abyssal plain
- Sediments are transported down the slope of the continental margin by turbidity currents
- Abyssal Plain
- Deep Ocean Basin 3-5km deep
- covered by thin beds of fine grained, slowly deposited pelagic sediment
- PELAGIC is organisms living in, and sediment deposited from, the main body of sea water
- the area has no earthquakes
- thicker deposits of coarser sediment is carried by turbidity currents
- Deep Sea Trench
- Very deep (up to 11km)
- elongated submarine valley occuring at the edges of the oceans
- Shallow-focus earthquakes
- Seamounts
- Submarine basalt volcano rising at least 1000m above ocean floor without reaching sea level
- Some are topped by coral atoll
- A seamount with an eroded top is called a GUYOT
- Continental Shelf
