Russia.
1)Climate:
Most of Northern European Russia and Siberia has a subarctic climate, with extremely severe winters in the inner regions of Northeast Siberia (mostly the Sakha Republic, where the Northern Pole of Cold is located with the record low temperature of ?71.2 °C or ?96.2 °F), and more moderate elsewhere. The strip of land along the shore of the Arctic Ocean, as well as the Russian Arctic islands, have a polar climate. The coastal part of Krasnodar Krai on the Black Sea, most notably in Sochi, possesses a humid subtropical climate with mild and wet winters. Winter is dry compared to summer in many regions of East Siberia and the Far East, while other parts of the country experience more even precipitation across seasons. Winter precipitation in most parts of the country usually falls as snow. The region along the Lower Volga and Caspian Sea coast, as well as some areas of southernmost Siberia, possesses a semi-arid climate.

2)Landscape:
Russia is the largest country in the world; its total area is 17,075,400 square kilometres (6,592,800 sq mi).
Most of Russia consists of vast stretches of plains that are predominantly steppe to the south and heavily forested to the north, with tundra along the northern coast. Russia possesses 10% of the world's arable land.[151] Mountain ranges are found along the southern borders, such as the Caucasus (containing Mount Elbrus, which at 5,642 m (18,510 ft) is the highest point in both Russia and Europe) and the Altai (containing Mount Belukha, which at the 4,506 m (14,783 ft) is the highest point of Siberia outside of the Russian Far East); and in the eastern parts, such as the Verkhoyansk Range or the volcanoes of Kamchatka Peninsula (containing Klyuchevskaya Sopka, which at the 4,750 m (15,584 ft) is the highest active volcano in Eurasia as well as the highest point of Asian Russia). The Ural Mountains, rich in mineral resources, form a north-south range that divides Europe and Asia.
