Answer:
This all has to do with the location of the two areas.
Explanation:
Siberia is farther away from the equator, therefore, the sun does not make direct contact with it. The equator is the middle of the earth, and because it gets more exposure to sunlight, and the sun is always directly above them in the sky, the climate is very different from areas in places like Russia, Canada, and Iceland.
Answer:
Sediments are used to provide the proxies to understand the environmental changes as, the sediments are formed by the activity of the weathering from the wind, glacier and the water. The different weathering agent and other transportation agent are different types of the mark over the sediments that help in the study of the past environment.
I'm pretty sure it's railroads, because there's not that many highways in Siberia, the rivers would be frozen over, and there's not a ton of people in Siberia. I'm sorry if I'm wrong.
