Topic 1: James Cameron/ Deep sea challenger
Q 1: who discovered the deep sea challenger?
A 1: James Cameron
Q 1:in which layer do earthquake occur?
A 1: In the Crust
Q1: what is AUV and ROV stands for?
A1: remotely operate vehicle and Human occupied vehicle.
Q1: what are plate tectonics?
A1: is the theory that earth's outer shell is divided into several plates that glide over the mantle above the core.
Q1: Define Seamount?
Q 2: what are the new species did James Cameron discover?
A 1: sea Cucumber/ squid warm
Q 2: which is the only layer that is completely liquid?
A 2: the outer core
Q2: why are ROVs so important to the scientists?
A2: because its allows them to explore all around the ocean without being in it.
Q2: why is the study of plate tectonics is a part of oceanography?
A2: because the plate tectonics of earth are important, it makes us understanding about earth layers features, such as submarine trenches,mid-ocean ridges etc...
Q2: Trench
A2: a long, deep and narrow depression of the seafloor
Q 3: Who 've reached to the bottom of the Mariana trench first ?
A 3: James Cameron
Q3: give 3 facts about mantle
Q3: the mantle is mostly solid rock/ convention in the mantle drives tectonics
Q3: How deep can ROVs go?
A3: ROVS can go down to a maximum operating depth of 4500 meter.
Q3: what had to be learned about earth before Alfred Wegener ideas could be accepted?
A3: the mechanism that caused continental to break apart and drift plate bounderies.
Q3: continental rise
A3: a general slope formed by the deposition of sedments at the base of continetal slope
Q 4: when did James Cameron dive into the Mariana Trench?
March 26, 2012
Q 4: which core is the hottest?
A 4: the Inner core
Q4: what features does HOVs have or equipment?
A4: It has lights, Cameras,sensors etc...
Q4: what mechanism have been proposed to account for plate motion?
A4: surface of the earth covered by crustal plates and other plate that resulting in a creation of new seafloor destruction of seafloor.
Q4: shoreline
A4: a strip of ground bordering any body of water and altenally exposed by tides.
Q 5: During the Dive 10th, how far did James Cameron go?
A 1: Depth 35,756 feet
Q 5: Name 8 layers
A 5: Ocean crust, continental crust, crust, lithosphere, outer core, convection currents, and inner core
Q5: What are the AUVs? (autonomous underwater vehicle)
A5: the are robots that can drift, dive or glide through the ocean without real-time control by human operators
Q5: in which layer do the convection drives plate tectonics?
A5: Mantle convection
Q5: Guyot
A5: the submerge that tapped seamount.
