Answer:
The Russian Core region is located in the heart of Russia and encompasses the vast expanse of the Russian Plain, also known as the East European Plain. The region is characterized by a temperate continental climate, with long, cold winters and short, warm summers. The average temperature in January ranges from -12 to -20 degrees Celsius, while in July it ranges from +15 to +20 degrees Celsius.
The Russian Plain is a flat, low-lying area, with few natural barriers to human settlement. The main physical feature of the region is its vast expanse of fertile black soil, which is ideal for agriculture. The region is also crisscrossed by major rivers such as the Volga, which has played an important role in the development of transportation and trade.
The climate and physical geography of the Russian Core region have played a significant role in the settlement of the area. The long, cold winters and short, warm summers have had a significant impact on the types of crops that can be grown in the region. The fertile black soil and the presence of major rivers have made agriculture the mainstay of the region's economy, and many villages and towns in the region have developed around agricultural production. The flat and open landscape also made it relatively easy for people to move into the region and settle, which is why it has a high population density.
In summary, the Russian Core region is characterized by a temperate continental climate and a flat, low-lying physical geography. The fertile black soil and the presence of major rivers have played an important role in the settlement of the area, making agriculture the mainstay of the region's economy and the reason for high population density.
