The process of erosion or the wearing away of soil and rock will most likely causing people to move from coastal cliffs. Many coastal cliffs have been worn away by this process and houses and roads are in danger of being destroyed by this process.
Answer:
Acid precipitation begins when compounds such as sulfur dioxide and nitrogen oxide emanating from pollution (which come from factories, vehicles, power plants, and boilers) <u>mix with water or oxygen</u> in the atmosphere.
Explanation:
Acid precipitation is produced by the concentration of <em><u>nitrogen oxides and sulfur dioxide </u></em>that react with particles of water or oxygen in suspension in the atmosphere, creating <em><u>nitrogen acids and sulfur acids.
</u></em>
These concentrations of oxides and dioxides are, above all, created by the human hand, due to the vapors emanating from the burning of fossil fuels.
In addition to the fact that this rain contaminates any body of water with which it has contact,<u> destroying entire aquatic ecosystems.</u>
Answer:
recession constant = 0.9819
Q(97) = 815.6910 m³/s
Explanation:
given data
on June 7, 2018
flow = 4790 m³/s
august flow declined = 1,631 m/s
time = 59 day from June 7, 2018 i.e on August 5, 2018
time = 97 days from June 7, 2018 i.e on September 12, 2018
solution
we know here equation that is
Q(t) = Q(o) 
here Q(t) is flow at any time t and Q(o) is initial flow and
K is recession constant i.e 
so first we find recession constant
Q(t) = Q(o)
put here value
1631 = 4790 
take ln both side
-1.07733 = - 59 a
a = 0.01825
so
recession constant =
recession constant = 
recession constant =
recession constant = 0.9819
and
flow after 97 day that is on 12 September
Q(97) = 4790 
Q(97) = 815.6910 m³/s
The closess is number 1
hope that helps
