Somewhere around the third or fourth section, this article's complexity suddenly jumps about eight grade levels - it's simply a mash of terms with little explanation made for each. I might try my hand at fixing this. ZS16:39, 5 October 2009 (UTC)reply
I've been trying to make incremental improvements. If I get ambitious, I'll incorporate some of the references into inline citations while I'm at it. Anyone else who wants to contribute to this effort is welcome.

Cross-section please?
The section on morphological expression is begging for a cross-sectional illustration and/or clear bathymetric example with labels of the 'outer rise', 'outer slope' and 'inner slope'.

Thanks! I didn't expect anyone to be that fast. They're not perfect for this purpose, but these images are a good step in the right direction.

Great, thanks! In addition, in Morphology, last paragraph starting with "As the subducting plate approaches the trench", it talks about "bending faults that give the outer trench slope a horst and graben topography". The Horst and Graben slats, do they run parallel to the trench axis, or perpendicular? Hard to imagine anything spreading there. Tx.

Parallel to the trench generally, although older inherited structures could potentially alter this a bit. As the downgoing slab flexes, the outer (upper) part will be extended, forming normal faults.
