Answer:
Option A, Trees were cleared from a mountainside, causing an increase in soil erosion
Explanation:
The reason behind Alpine river getting muddier is that the surface runoff from the near by catchment areas consist of increased content of soil, clay, silt and debris.
This is possible only when the soil in the surrounding regions is loose enough to be carried away by water. And this is possible only when the trees in the near by areas are cut at a fast rate thereby leaving loose soil behind.
This loose soil is carried by water which drains into Alpine river and thus makes it muddier
Hence, option A is correct
The answer is A because since the trees are being cut the soil runs off to the river banks
Answer:
A: Disruption to electricity power grid.
A decrease in plant life would have no effect on the atmosphere.
b.
A decrease in plant life would cause carbon dioxide levels to increase and oxygen levels to decrease.
c.
A decrease in plant life would cause carbon dioxide levels to decrease and oxygen levels to increase.
d.
A decrease in plant life would cause an increase in all gases in the atmosphere.
A decrease in plant life would cause carbon dioxide levels to increase and oxygen levels to decrease. Therefore option B is correct.
Plants play a crucial role in the biosphere by performing photosynthesis, a process that absorbs carbon dioxide (CO2) from the atmosphere and releases oxygen (O2) as a byproduct.
With a decrease in plant life, the rate of photosynthesis would decrease, resulting in reduced CO2 absorption and lower oxygen production.
As a consequence, carbon dioxide levels would increase in the atmosphere, leading to potential implications for global warming and climate change.
Additionally, the decrease in oxygen production could have adverse effects on the air quality and the oxygen supply necessary for supporting aerobic life forms.
Thus, the reduction of plant life could disrupt the delicate balance of atmospheric gases, influencing the Earth's climate and living organisms.
Therefore option B A decrease in plant life would cause carbon dioxide levels to increase and oxygen levels to decrease. is correct.
