Which of the four belts in Russia is characterized by barren land?

The Barren Steppe is characterized by dry, inhospitable conditions that result in minimal vegetation and a landscape primarily consisting of sparse grasslands and bare soil. This region typically experiences extreme temperatures, limited precipitation, and harsh winds, which contribute to its classification as "barren." The lack of significant plant life and agricultural viability in this area further emphasizes its arid nature.

In contrast, the Taiga is known for its dense forests, primarily consisting of coniferous trees. The Black Land, often associated with fertile soil suitable for agriculture, is abundant in organic matter and conducive to farming. The Arable Steppe, while also having grasslands, supports agricultural practices more effectively due to better climatic conditions and soil fertility compared to the Barren Steppe. These distinctions highlight why the Barren Steppe is recognized specifically for its lack of vegetation and agricultural potential.
