Answer: </u></h2>
<u>Erosion:</u> is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.Erosion is the opposite of deposition, the geological process in which earthen materials are deposited, or built up, on a landform.
Most erosion is performed by liquid water, wind, or ice . Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment.
<u>Public domains:</u>VegetationThe simplest and most natural way toprevent erosion is through planting vegetation. Plants establish root systems, which stabilizes soiland prevents soil erosion. Geotextiles: Using geotextiles is an effective method because it also stabilizes soi

The use of sandbags is a simple, but effective way to prevent or reduce floodwater damage. Properly filled and placed sandbags can act as a barrier to divert moving water around, instead of through, buildings. ... Tied sandbags are generally easier to handle and stockpile.

The answer is surface runoff
Nitrogen is the most abundant of the gases present in the atmosphere. 78
percent of the atmospheric air comprises of nitrogen, oxygen makes up
for 21 percent and all other gases make up for the remaining one
percent. Oxygen is a highly flammable gas and in the absence of nitrogen
it would not have been possible to utilize this atmospheric oxygen,
hence the presence of nitrogen reduces its flammability and also
neutralizes the toxicity of other gases. Another way to explain this question is - The vital thing about Nitrogen is that it gives air to people to take
in, 78% of the air we take in is Nitrogen and just 21% is oxygen, 1% is
different gasses. On the off chance that the air was unadulterated
oxygen then everything would be to a great degree flamable, and it would
likewise be hurtful to people. Nitrogen assumes a vital part in our
lives. Oxygen can be poisonious on the off chance that it was the main
gas noticeable all around... Nitrogen is too much critical, else we
would all die.... Also, I seek oxygen stays 21% after it can be
hazardous. Definitely, you ought to realize that Nitrogen can likewise
be risky in A few ways, you can look that up and take in more about it,
however at this moment we're looking at something else and I would
prefer not to be insignificant by any stretch of the imagination, so
I'll simply adhere to the Inquiry on the point as apose to the Entire
whole theme. I know I have addressed your inquiry, and I believe this
was useful.
Hope this helps
<h3><u>Answer;</u></h3>
acceleration= 2 m/s²
<h3><u>Explanation;</u></h3>
From the second Newton's Law of motion the resultant force is directly proportional to the rate of change in momentum.
That is;
F = ma
Thus; F = 100 N, m = 50 kg
a = F/m
= 100/50
= 2 m/s²
