Answer:Russia is probably richer in natural resources than any other country in the world. It has abundant supplies of oil, natural gas, and timber. And valuable minerals, such as copper, diamonds, lead, zinc, bauxite, nickel, tin, mercury, gold and silver. Most of which are located in Siberia and the Far East. Also the sell of these resources gives a major boost to the economy
As subconduction is a geologic process that takes place at the convergent boundaries. Where the one plate collides with the another plate that moves underneath the lighter plates. The subducting is the process that relates to the formation of the mountain building and is associated with the formation of volcanoes.
<u>The origin of the hotspots takes place due to the slow movement of the plate tectonics as they are fed by the narrow streams that come from the mantle and are related to the island formations like that of the hawaiian islands.</u>
Fertilizers and chemicals are important contaminants of water and enter ground both directly and indirectly. In the case of Karst landscapes, the contaminated water infiltrates into the groundwater through underground streams or percolation.
Oil and gas spills also pose a serious problem for groundwater contamination as they can pollute aquifers near fracking zones and other oil extraction areas.
Animal feces are more of a problem in the modern age due to large-scale commercialized animal farms. Unless the waste from these facilities is controlled, it can runoff into fields and rivers and eventually seep into groundwater reserves.
