Answer:
Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area. As an example, picture a city street during a thunderstorm. As rainwater flows over asphalt, it washes away drops of oil that leaked from car engines, particles of tire rubber, dog waste, and trash. The runoff goes into a storm sewer and ends up in a nearby river. Runoff is a major cause of nonpoint-source pollution. It is a big problem in cities because of all the hard surfaces, including streets and roofs. The amount of pollutants washed from a single city block might be small, but when you add up the miles and miles of pavement in a big city you get a big problem.
In rural areas, runoff can wash sediment from the roads in a logged-over forest tract. It can also carry acid from abandoned mines and flush pesticides and fertilizer from farm fields. All of this pollution is likely to wind up in streams, rivers, and lakes.
Airborne pollutants are major contributors to acid rain. It forms in the atmosphere when sulfur dioxide and nitrogen oxides combine with water. Because acid rain results from the long-range movement of those pollutants from many factories and power plants, it is considered nonpoint-source pollution.
Explanation:
To answer the question what is 77800000 in scientific notation let’s recall how to convert 77800000 to scientific notation as detailed on our home page.
When you split the number 77800000 into a coefficient and a power of 10 you do get 77800000 in exponential form, but there is an indefinite number of possibilities.
As you probably want 77800000 in normalized scientific notation, the coefficient or significand of 77800000 in scientific notation must be in the interval [1,10[.
As there are many ways to express 77800000 in scientific notation, in this post we mean 77800000 in normalized scientific notation, unless stated otherwise. Therefore:
77800000 in scientific notation = 7.78 × 107.
Answer:
All Three Populations Would Decrease
Explanation:
Dead zones have little to no life in them, and besides the fact that this would mean the popoulations of all of them would just be down because of this, mullet will die out due to nothing to feed on, which will make drums and trout also die out, so all of the populations would go down.
