The extension of a trough or basin penetrating the land or an elevation is termed an " embayment " when wide, and a " gully " when long and narrow; and the deepest part of a depression is termed a " deep."
- Mississippi lies for the most part in the Mississippi embayment of the Gulf Coastal Plain.
The entire state is included within the Austro-riparian life zone; the higher portions fall within the Carolinian area and the lower portions, including the Gulf and the Mississippi embayment almost to the N.E.
The extension of a basin or trough stretching towards the continent is termed an embayment when relatively wide and a gully when narrow.
The special features of the Gulf Plain are the peninsular extension of the plain in Florida, the belted arrangement of relief and soils in Alabama and in Texas, and the Mississippi embayment or inland extension of the plain half-way up the course of the Mississippi river, with the Mississippi flood plain there included.
In the embayment of the coastal plain some low cuesta-like belts of hills with associated strips of lowlands suggest the features of a beltedcoastal plain; the hillybeltordissected cuesta determined by the Grand Gulf formation in western Mississippi is the most distinct.
The most striking feature of the embayment is the broad valley which the Mississippi has eroded across it.
The head of the coastal plain embayment is near the junction of the Ohio and the Mississippi.
After constriction from the Mississippi embayment to 250 m.
The second important embayment is the estuary of the Columbia river; but theoccurrence of shoals at the mouth decreases the use that might otherwise be made of the river by ocean-going vessels.
The boundary between the prairie and Ozark regions follows the Missouri river from its mouth to Glasgow, running thence south-westward, with irregular limits, but with a direct trend, to Jasper county at the south-east corner of Kansas; and the boundary between the Ozark and embayment regions runs due south-west from Cape Girardeau.
The embayment region is of 'Tertiary origin, containing deposits of both neocene and eocene periods.
Excepting the embayment region, Missouri lies wholly within the Carolinian area of the Upper Austral life-zone; the There has been some controversy as to whether this condition is due to the elevation and corrosion of original flood-plain meanders after their development in a past base-level condition - which theory is probably correct - or to the natural, simultaneous lateral and vertical cut of an originally slightly sinuous stream, under such special conditions of stream declivity and horizontal bedstrata (conditions supposed by some to be peculiarly fulfilled in this region) as would be favourable to the requisite balance of bank cutting and channel incision.
Embayment lies in the Austro-riparian area of the same zone.
So far as these are an article of general commerce, they come, like frogs, terrapin and turtles, mainly from the counties of the embayment region.
Ash, oaks, black and sweet gums, chestnuts, hickories, hard maple, beech, walnut and short-leaf pine are noteworthy among the trees of the Carolinian area; the tupelo and bald cypress of the embayment region, and long-leaf and loblolly pines, pecans and live oaks of the uplands, among those characteristic of the Austro-riparian.
The south-eastern embayment is rich to an exceptional degree.
The Mississippi embayment is in parts predominantly sandy, in others clayey; it is mainly under timber.
Tobacco is grown over half the area of the state, but especially in the central and north-central counties, and cotton along the Arkansas border counties, but especially in the embayment lowlands.
Apples are grown to best advantage in the north-west quarter; peaches on the Arkansas border; pears along the Mississippi; melons in the sandy regions of the embayment; small fruits in the south-west.
Limestone is quarried all over the state (except in the embayment region).
