According to the source, the land in question is located in the Ternopol, Khmelnitsky, and Chernovitsky regions - fertile black soil farming areas in the western part of Ukraine.

One of the natural wonders of the region are its cave complexes.[5] Although Ternopil Oblast is among the smallest regions in Ukraine, over 100 caves have been discovered there.[5] Scientists believe these are only 20% of all possible caves in the region.[5] The biggest cave is Optymistychna Cave.[5] Measuring 267 km (166 mi) in total length, it is the longest cave in Eurasia and the fifth-longest in the world.[5] Twenty percent of the land in the region is chernozem soil.[5]

The oblast is located in Western Ukraine and has an area of 13,800 km2 (5,300 sq mi). It is situated at the western part of the Podilian Upland, which is known for its rocky terrain. Among noticeable mountains there are the Kremenets Mountains. The oblast is also famous for its caves.

One of the major rivers in the country Dniester forms southern and southwestern borders of Ternopil Oblast with the adjacent Chernivtsi Oblast and Ivano-Frankivsk Oblast. Its tributaries that flow through the oblast include Zbruch, Seret, and Strypa among just a few of them. The Seret River (not to be confused with Siret nor Seret) is a left tributary of the Dniester flowing through the oblast administrative center, i.e. Ternopil.

Ternopil Oblast is one of two oblasts in West Ukraine that do not have an international border. It is surrounded by five other oblasts of Ukraine: Chernivtsi Oblast – to the south, Ivano-Frankivsk Oblast – to the southwest, Lviv Oblast – to the northwest, Rivne Oblast – to the north, and Khmelnytskyi Oblast – to the east.

Khmelnytskyi Oblast has a total area of 20,600 km2 (7,953.70 sq mi) (3.4% of the total area of Ukraine).

The oblast borders the Rivne Oblast to the northwest, the Zhytomyr Oblast to the northeast, the Vinnytsia Oblast to the east, the Chernivtsi Oblast to the south, and the Ternopil Oblast to the west.

The Podolian Upland (270–370 meters above sea-level) occupies the central area of the Khmelnytska oblast. The northwestern areas of the oblast are part of the Volyn highland (highest point — 329 m above sea-level), while to the north, the oblast claims a part of the historic region of Polissia (highest point — 200–250 m above sea-level). The southwestern territory of the Khmelnytska oblast is crossed by the Tovtry range (Ukrainian: Товтровий кряж, translit. Tovtryi kryazh), which includes Mount Velyka Buhaikha (Ukrainian: Велика Бугаїха), the highest point of the oblast at 409 m above sea-level. The extreme south of the oblast has a surface with canyon-like river valleys. The Dneister Reservoir located there is the lowest point of the oblast (121 m above sea-level) .

Chernivtsi Oblast (Ukrainian: Черніве́цька о́бласть, romanized: Chernivetska oblast), also referred to as Chernivechchyna (Чернівеччина), is an oblast (province) in western Ukraine, consisting of the northern parts of the historical regions of Bukovina and Bessarabia. It has an international border with Romania and Moldova. The region spans 8,100 square kilometres (3,100 sq mi). The oblast is the smallest in Ukraine both by area and population. It has a population of 890,457 (2022 estimate),[3] and its administrative center is the city of Chernivtsi.

The oblast has a large variety of landforms: the Carpathian Mountains and picturesque hills at the foot of the mountains gradually change to a broad partly forested plain situated between the Dniester and Prut rivers.

In the oblast there are 75 rivers longer than 10 kilometers. The largest rivers are the Dniester (290 km, in the Oblast), Prut (128 km, in the Oblast) and Siret (113 km, in the Oblast).[5]

Chernivtsi Oblast is bordered by Ivano-Frankivsk Oblast, Ternopil Oblast, Khmelnytskyi Oblast, Vinnytsia Oblast, Romania, and Moldova. Within the oblast the national border of Ukraine with Romania extends 226 km, and with Moldova 198 km (123 mi).[5]
