River Delta
2013-04-18 22:36:25

A river delta is a landform that is created at the mouth of a river, where the river flows into an ocean, estuary, lake, sea, or reservoir. These deltas are built from the deposition of the sediment that is carried by the river as the flow exit’s the mouth of the river. Over a long period of time, this deposition constructs the distinctive geographic pattern of a river delta. The creation of a delta is made up of three core forms: the bottomset, topset, and foreset/frontset. Bottomset...

In geology, a conglomerate is a rock consisting of other stones that have been cemented together. Conglomerates are sedimentary rocks consisting of subangular clasts and are thus differentiated from breccias, which consist of angular clasts. Both conglomerates and breccias are characterized by clasts larger than sand (>2 mm). There are two varieties of conglomerate, defined by texture: paraconglomerates and orthoconglomerates. Paraconglomerates are one of two varieties of conglomerate...
