A bunch of Scandinavian warriors and merchants, who were actually called Varangians, started expanding into Russia during this time, subduing the local Slavic tribes & forming the Kievan Rus.
The upliftment weathering hypothesis suggests that the formations of the uplifted terrains the global climate into an icehouse state and the main factor that influences the global state of the chemical weathering are the global rainfall and the high temperatures, like the rocks in the tropical areas, are exposed to the dry and hot weather conditions.
<u>Similar to that of the cold areas the rocks are exposed to the cold and first action and the interaction of the moisture contents that transform the minerals in the rocks. Which are ongoing processes through the impacts of the oxidation and hydrolysis.
</u>
The formation of the acidic contents in the rocks ios created by the impacts of these temperatures on the rocks mass. The carbonization that is an atmospheric process of the addition to carbon contents to the air and impacts the limestone and the chalk rocks.
