The Moldavian Plateau was formed at the end of the Neogene through sediments, over an old continental platform, the East European Platform. Afterwards, the settled sediments, which were brought in by rivers from the Carpathian Mountains, were modeled by the elements giving the plateau its current aspect. The materials that formed the sediments are gravel and sand. Hardened, they formed gritstones. All over the plateau, the latter are interspersed with clays, or badlands, which produce landslides. The slope of the terrain follows the direction of the rivers: from northwest to southeast. Along them, the altitude decreases from to under. The strata are disposed in North-South and northwest-southeast aligned layers, producing asymmetric valleys and ridges. Among the latter are the steep edge of the Bârlad Plateau, known as the Iași Ridge, the edge of the Central Moldavian Plateau, known as the Cornești Hills, and the edge of the Dniester Hills, known as the Dniester Ridge. The relief in the valleys of the rivers and creeks is quite conspicuous, so that the valleys have large terraces and hillocks. The Siret Passage, ramified in the north with the Moldova Valley, and Suceava Valley cuts the main part of the plateau from the Moldavian Subcarpathians. The Prut Passage cuts the Plateau in half in the north-south direction. The Dniester Passage bounds it from the Podolian Plateau and the Pontic Plain. Its ramification Răut Passage separates the main part of the Moldavian Plateau from the Dniester Hills
Composition
The Moldavian Plateau comprises several distinct regions:
The Moldavian Subcarpathians in the west and southwest, has altitudes of up to, but also includes depressions.
The Suceava Plateau, situated in the northwest, has altitudes that exceed and long ridges.
The Dniester Hills, also known as Northern Moldavian Plateau, situated in the north and northeast, ridges along the Dniester River and has elevations of approximately.
The Moldavian Plain, in the center-north has elevations of approximately :
* The Middle Prut Valley, east of the river Prut, creeks tributary to the Prut,.
* The Bălți Steppe, east of the river Prut, creeks tributary to the Dniester,.
The Bârlad Plateau, situated in the south-center occasionally has heights over, but is generally sloped from north at to the south at.
The Central Moldavian Plateau, situated in the center and southeast, has elevations that in the north-south direction decrease in altitude from to under.
The climate of this plateau is transitional TemperateContinental. Overall, the altitude affects the climate, with annual mean temperatures in the Suceava Plateau ranging between and and precipitation of to per year and, with annual mean temperatures of to and precipitation of to in the Moldavian Plain or Bârlad Plateau. The main influence on the climate is Dry Continental with frequent cold north winds in winter. In the Suceava Plateau and the Dniester Hills, there is an influence of Scandinavo-Baltic climate with the circulation of masses of polar air in the winter.
Waters
Streams on the plateau flow into the Siret, Prut, or Dneister rivers. The Prut has the Jijia as its principal tributary. The Siret traverses and—with the exception of the Subcarpathians—limits the Moldavian Plateau The lack of precipitation has required water management in the Jijia Plain and in the Bălți steppe which serves as a reservoir and for fish farming; Lake Dracşani is the most largest of these. Other bodies of water are the rivers Siret and Prut, in the Siret Passage.
Natural resources
The Moldavian Plateau holds hydrocarbon resources, which are extracted in the southwest portion. In the northwest are found Romania's most important reserves of kaolin, extracted and used to produce porcelain. Hemp is cultivated in the Suceava plateau, cereals and wine grapes in the Jijia Plain, Bălți steppe, Bârlad Plateau and Central Moldavian Plateau. In the Siret Passage they cultivate potatoes and sugar beets.
Animals
Characteristic of the plateau are mammals such as goats, wild boars, wolves, foxes, European wildcats, lynxes, badgers, and hares. Birds include black grouse, woodpeckers, cuckoos, pheasants, quails, hawks, owls, and fish include perch and the carp-like barbel.
