5The US Navy developed [blank_start]SONAR[blank_end] to track German U-Boats during [blank_start]WWII[blank_end]. It provided boats w/ a quick way to map the ocean [blank_start]floor[blank_end]. Before this, they used rope.

8[blank_start]Alvin[blank_end] is a [blank_start]DSV[blank_end] owned by the Woods Hole Oceanographic Institute and operated by Dr. Bob Ballard. This submersible is very famous and
has made from fascinating discoveries. It was used to discover the [blank_start]Titanic[blank_end] as well as deep sea trenches, hydrothermal [blank_start]vents[blank_end], and many other deep ocean features.- AAlvin

113 methods used by scientists to study the ocean floor:
*Echo Sounding ([blank_start]SONAR[blank_end])
*[blank_start]Sediment[blank_end] Cores
*[blank_start]Satellites[blank_end]- ASONAR
- BSediment
- CSatellites
12Submarine Canyons:
Submarine canyons were formed by extensive [blank_start]erosion[blank_end] either from a river entering the continental shelf, [blank_start]earthquakes[blank_end], or turbidity currents (a large
underwater [blank_start]avalanche[blank_end] of sediment).- Aerosion
- Bearthquakes
- Cavalanche
13Continental Shelf: extends from the [blank_start]continent[blank_end] to the continental slope; composed of sediments
Passive Margins: [blank_start]no[blank_end] tectonics [ex) east coast]
Continental Slope: water depth begins to [blank_start]in[blank_end]crease rapidly; steep drop off to the ocean bottom.
Continental Rise: pile of [blank_start]sediment[blank_end] lying on the ocean crust at the base of the continental slope.
Active Margins: [blank_start]yes[blank_end] tectonics [ex) japan]- Acontinent
- Bno

14[blank_start]Abyssal[blank_end] Plain: large flat area of the ocean covered in sediment.
[blank_start]Trench[blank_end]: deep ravine feature located at convergent boundaries.
Mid-Ocean [blank_start]Ridge[blank_end]: linear mountain range under the ocean with a rift valley in the middle; located a divergent boundaries
[blank_start]Volcanic[blank_end] Island: when a seamount breaches the surface of the ocean
[blank_start]Guyot[blank_end]: seamount has been flattened on top by current action
[blank_start]Seamount[blank_end]: underwater mountain of volcanic origin- AAbyssal
- BTrench
- CRidge
- DVolcanic
- EGuyot
- FSeamount
15Atolls: 1st described by [blank_start]Darwin[blank_end]. A ring of [blank_start]coral[blank_end] reefs around a [blank_start]volcanic[blank_end] island. Once the volcano goes extinct, it begins to [blank_start]sink[blank_end]. Eventually, a circle of coral is left in the middle of the ocean with a lagoon in the middle.
