Answer:
a) horizontally
Explanation:
If the sewage sludge is disposed of into the deep water , then the density gradient separates the surface water from the deep water,
the internal waves transport wastes horizontally .
<u>When the transport of the particles is dominated by the tides ,wind and the density gradients, the movement is essentially in horizontal direction whereas the vertical transport of the particles is mainly driven by gravity and also by some other processes that occur at the sediment-water interface.</u>
Answer:
The statement is true. Las Vegas, Nevada, has seen a great increase in the demand for water since it is one of the fastest growing regions in the U.S.
Explanation:
Las Vegas is the most populous and most densely populated city in the state of Nevada. It is located in the south of the state, in Clark County.
According to the 2010 national census, the city itself has 583,756 inhabitants, and its metropolitan region has about 1.9 million inhabitants. It is the 30th most populous city in the United States and is considered to be the fastest growing city in all of North America.
Population growth was especially marked in the 1990s, when the population went from a little over 200,000 people to more than 500,000. This brought a consequent lack of resources due to the desert location of the city, which was solved only with investment in infrastructure by the state government.
The math suggests that for every parsec the rate of moving away is 71 km/s, so when two galaxies are separated by two parsecs we come to 142 km/s speed of moving away from each other. If we take the first light ever (from what is known so far) the cosmic microwave radiation, is 46 billion light-years away from us at all directions, which comes at 4,200 megaparsecs, which comes at 13.7 billion light-years, so it will come to 29,820,000 km/s. It all depends from the distance between the galaxies which is calculated by their type of colour and movement in comparison to other galaxies.
