River delta, an Uncommon card

The card carries these facts from its Wikipedia article.

• The creation of a river delta occurs at the river mouth, where the river merges into an ocean, a sea, or an estuary, into a lake, a reservoir, or into another river that cannot carry away the sediment supplied by the feeding river.
• Etymologically, the term river delta derives from the triangular shape of the uppercase Greek letter delta.
• In hydrology, the dimensions of a river delta are determined by the balance between the watershed processes that supply sediment and the watershed processes that redistribute, sequester, and export the supplied sediment into the receiving basin.
