Russia spans forest, steppe, tundra, and high mountain regions. A wide view of western Siberia can show broad lowlands and extensive drainage networks; farther east, rugged terrain becomes more prominent. The map here covers most of Eurasian Russia but does not include the full area across the antimeridian.
A country too large for one visual shortcut
Compare the lowlands east of the Urals with more mountainous eastern Siberia. Use the river pattern to describe the relief you can actually see.
Similar landscapes across borders
Canada has comparable boreal and Arctic landscapes, while Kazakhstan shares steppe and agricultural patterns. A small crop of trees or fields may not contain enough evidence to distinguish them. Avoid forcing a precise regional guess from colour alone.
