1- Remember back to your previous labs on plate tectonics. Using Slides 3 - 9, match points A to G to the given names below and give a brief explanation on how they are formed. Using the depths of abyssal plain, continental shelf, mid-ocean ridge, trench, and continental slope is a smart way to identify the correct locations. For passive or active margins, ask yourself if the feature is close or away from a plate tectonic boundary. Recommendation do these two last.

Mid-Ocean Ridge:

Continental Shelf:

Continental Slope:

Active Continental Margin:

Passive Continental Margin:

Oceanic trench:

Abyssal Plain:

2- Go to Slide 10 and look at the cross-section line labeled A to A'. Click on the image. Sketch what you see. You can use the provided elevation profile image on this slide for help. Label the different areas of your cross-section using the applicable terms from Question 1. What type of margins (active/passive) lies along this transect?

Type of Continental Margin: ________________________________________

3- Continue to Slide 11 where you will see a shaded polygon feature. What type of mass wasting is going on in this highlighted region? Exit out of "Present" mode, and activate the measurement toolto estimate the area (in km2) of this landform. (Tip: With the measurement tool open, use your mouse to click and outline around the provided polygon. Connect your last point with the first point to "close the shape." Your estimated area will appear in the upper-right box.)

Mass wasting type: ________________________________________

Area in km2:_____________________________________________

What natural hazard is usually associated with events like this one?

4- Remember to go back to "Present" mode after measuring. Open Slide 12 to look at the cross-section line labeled B to B'. Sketch a cross-section of the ocean floor elevation along that line. Again, an elevation profile image is provided in this slide as a guide. Describe the types of landforms this line transects as part of your answer.
