The [[Danubian Plain (Bulgaria)|Danubian Plain]] encompasses the Moesian plate and extends from the river Timok in the west to the Black Sea in the east and from the river [[Danube]] in the north to the Balkan Mountains in the south, covering 31,520&nbsp;km<sup>2</sup>, or almost 1/3 of Bulgaria's total area.<ref>{{harvnb|Donchev|Karakashev|2004|pp=34, 92}}</ref> Its width varies from 25 to 30&nbsp;km in the west to 120&nbsp;km in the east. The highest point is Tarnov Dyal (502&nbsp;m) on the [[Shumen Plateau]]; the average altitude is 178&nbsp;m.<ref name="donchev92">{{harvnb|Donchev|Karakashev|2004|p=92}}</ref> As a result of the rock weathering processes the relief is uneven with fertile [[alluvial plain]]s along the Danube (Vidinska, Chernopolska, [[Zlatia (region)|Zlatia]], Belenska, Pobrezhie, Aidemirska), and hilly terrain in the remaining area, including plateaus in the east. The altitude rises from west to east. The valleys of the rivers [[Vit (river)|Vit]] and [[Yantra River|Yantra]] divide the Danubian Plain into three parts&nbsp;– western, central and eastern.<ref name="donchev92"/> The topography of the plain is characterized with hilly heights and plateaus. Most of the heights and all plateaus are situated in the eastern parts. There are 14 [[basalt]] mounds between [[Svishtov]] and the village of [[Dragomirovo, Veliko Tarnovo Province|Dragomirovo]].<ref name="donchev34">{{harvnb|Donchev|Karakashev|2004|p=34}}</ref>

The predominant soil types are [[loess]] in the north, reaching a depth of up to 100&nbsp;m at the banks of the Danube, and [[chernozem]] in the south.<ref name="donchev93">{{harvnb|Donchev|Karakashev|2004|p=93}}</ref> The climate is [[temperate]]. The flat relief and the openness of plain to the north facilitate arrival of moist air masses in spring, summer and autumn. In winter the Danubian Plain falls under the influence of the Eastern European anticyclone, which brings cold Arctic air masses.<ref name="donchev93"/> The mean temperature in January is −1&nbsp;°C and in July is 24&nbsp;°C, making it the geomorphological region with the highest average annual amplitude in Bulgaria&nbsp;– 25&nbsp;°C.<ref name="donchev93"/>
