Sometimes it is also categorized as including Mazovian-Podlasian Lowlands which together form part of the greater North European Plain.

As the area was the southernmost border of the ice sheet's presence, the northern and southern parts of the plain differ significantly: the former is a vast open space while the latter is more rough terrain.

The central part of the Mazovian Lowland, the so-called Warsaw Cauldron, as well as the valleys of Radomka and Pilica rivers are covered by a number of parabolic dunes.

The soils are mostly of bielica type, that is white sands on a layer of glacial age clay and sedimentary rocks.

The climate of Mazovian Lowland is temperate continental, with average temperatures in summer period ranging from 18 °C to 18,5 °C.
