Answer: Light years is a form of measurement like km

so 31536000 x 299792458 is 9,454,254,955,488,000 meters a year which to simplify it and not needing to say that many numbers we say one light year.

Romashka [77]

Answer: An erosion of soil which enters waterways

Explanation:

Acidic water is more poisonous to human, animal and plant life so if acidic water were to wash into a river that humans drink, the health risks posed to those humans would increase.

If there were plants and animals connected to the river, the risks to them would increase as well and disrupt their life cycle.

Acidic water does not make water more or less capable of soil erosion so the water being acidic would not contribute to soil erosion.
