1Which is false about how the bottom topography of the ocean is determined?
- AEcho sounding makes use of the propagation of sound through water
- BSensors mounted on satellites can accurately measure the sea surface height, which is related to ocean bottom
- CSubmarines can survey the bottom by shining light
- DRopes and weights were used in the days of the Challenger expedition
- ENone of the above
2Which is false about the scientific method?
- AIt is an iterative process that involves observations, conjecture, prediction and testing
- BObservations inconsistent with theory can lead to the theory being rejected
- CScientific "theories" are really just theories with no strong basis to support them
- DScientific theories cannot be definitively proven correct
- ENone of the above
3Plate tectonics can explain many features on the globe. Which of the following statements is false?
- AHimalayan mountains formed as a result of convergence of continental plates

- ENone of the above
4Many deltas today are decaying. Which of the following is NOT a major contributing factor?

5Which of the following is evidence in support of plate tectonics?

6Which is true about sediment transport in the ocean and bottom topography?
