1. if you traveled by ship eastward across the atlantic ocean from new york, new york, to lisbon, portugal, where would you expect to traverse the deepest water? are the deepest waters along this transect found in the middle of the ocean, halfway across the atlantic or are they found elsewhere?

2. does the magnitude of earthquakes increase with depth? in other words, do shallow earthquakes (< 50 km deep) have lower magnitude (i. e. lower numbers on the richter scale) than deep earthquakes (> 250 km deep)? what factors likely control earthquake magnitude?

3. a significant part of module explores the nature of earth's interior. how fast do tectonic plates move? is their motion typically measured in terms of km/yr or m/yr or mm/year or µm/year or nm/yr (i. e. are annual rates of motion in the range of kilometers, meters, millimeters, micrometers or nanometers)?

4. how does the temperature of the deep ocean compare with that of the surface ocean? do the temperatures at the seafloor vary seasonally, like those of the overlying surface waters?
