Why is the Great Siberian plains marshy and swampy?
Answers
Explanation:
Many of the deposits on this plain result from ice dams that reversed the flow of the Ob and Yenisei rivers, redirecting them into the Caspian Sea, and perhaps the Aral Sea as well. It is very swampy and soils are mostly peaty Histosols and, in the treeless northern part, Histels.
Answer:
Difference in latitudes
Melting of rivers
Difference in temperature

Northern lowlands are drained by North flowing rivers like of OB, Yensie and Naina. The volume in these rivers increases during the spring and summer time due to the melting of ice. The southern region is higher than the northern region so the flow and rate in the Arctic ocean. The lower courses near the Arctic coastline still frozen and blocked by ice as it is close to the Arctic Circle which is a frigid zone. So the river waters overflow to the surrounding planes giving rise to the vast marshlands as the soil absorbs these waters. Use lakes like Lake Caspian and Baikal add more water for the formation of marshland biy rivers have major role. This land becomes unfit for cultivation as it is swampy and marshy.
