I read practically the whole article, still have no idea what deltas are or why that matters.
On Earth, deltas form when rivers slow down as they reach larger bodies of water. These formations are important to scientists because they preserve geological, climatic, and even biological history over long periods.
So the article is saying that Titan’s lack of deltas is surprising because of its active river systems of methane and ethane.
Means that maybe we're wrong to assume that wherever there are flowing rivers of liquid and sediment, deltas will naturally form.
I guess it’s good we have another world nearby that has liquid other than water so we don’t make generalizations there.
Well it is pretty far away. And the whole point of the article was we are learning new things every day about planetary processes.
