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

- 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

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