Problem 1
Describe the main differences between oceans and continents.
Problem 2
Sketch a cross section of the Mid-Oceanic Ridge, including the rift valley.
Problem 3
Describe the dimensions of the Mid-Oceanic Ridge.
Problem 4
Explain why the Mid-Oceanic Ridge is topographically elevated above the surrounding ocean floor. Why does its elevation gradually decrease away from the ridge axis?
Problem 5
Explain the origin of the rift valley in the center of the Mid-Oceanic Ridge.
Problem 6
Why arc the abyssal plains characterized by such low relief?
Problem 8
Describe the two main types of sea-floor sediment. What is the origin of each type?
Problem 9
Compare the ages of oceanic crust with the ages of continental rocks. Why are they so different?
Problem 11
Explain how a continental shelf-slope-rise complex forms on a continental margin.
Problem 12
Why does an active continental margin typically have a steeper continental slope than a passive margin?
