a)

Expert Solution
Check Mark

Answer to Problem 1GST

At an average, the ice advance in the centre of the glacier is about 115 meters per year.

Explanation of Solution

The given diagram shows the pattern of movement of glacial ice in a mountain valley. This is the result of 8-year span of observation. The distance at the centre of the glacial is plotted as 920 meters. Therefore, in 8 years it travelled 920 meters.

b)

To determine

The speed in the centre of glacier per day.

b)

Answer to Problem 1GST

The speed of the centre of glacier per day is about 0.32 meters or 32 centimetres per day.

Explanation of Solution

The given diagram shows the pattern of movement of glacial ice in a mountain valley. This is the result of 8-year span of observation. The distance at the centre of the glacial is plotted as 920 meters. Therefore, in 8 years it travelled 920 meters. Therefore, per year it travels 115 meters. A year constitutes of 365 days.

c)

To determine

The average rate at which ice advanced along the side of the glacier.

c)

Answer to Problem 1GST

The glacial ice moves at the rate of 40 meters per year and 10.95 centimetres or 0.10 meters per day, along the sides.

Explanation of Solution

The given diagram shows the pattern of movement of glacial ice in a mountain valley. This is the result of 8-year span of observation. The distance at the centre of the glacial is plotted as 920 meters and at the sides of the glacier is plotted as 320 meters. A year constitutes of 365 days.

d)

To determine

The reason for the difference in the rate along the sides of glacier from its center.

d)

Expert Solution

Answer to Problem 1GST

Due the operation of frictional force, the movement of the glacier gets slower at the sides of the glacier when compared to the centre.

Explanation of Solution

The given diagram shows the pattern of movement of glacial ice in a mountain valley. This is the result of 8-year span of observation. The distance at the centre of the glacial is plotted as 920 meters and at the sides of the glacier is plotted as 320 meters.

Along the sides of the valley, there occurs the frictional force between the valley side and glacier apart from the bottom of the glacier.

There is an old axiom (a self-evident or universally recognized truth) of economics that “There is no such thing as a free lunch”. In the United States, stringent, enforced water quality laws and regulations provide a high level of protection of our waters. This is accomplished at a significant cost. For example, (sewage treatment plants use 2% of the electricity produced in the United States. This high level of protection increases the cost of goods manufactured in the United States compared to other nations such as China where standards are lower, enforcement a bit lax and in some cases, non-existent. What five (5) things could be done to “level the playing field” so that all manufacturers must provide the same degree of water quality protection no matter where in the world they are located? include how each of your ideas will be implemented (ex: which organization will be provided the power and resources to make sure each idea happens). These should be only about water pollution,…
Connecticut is the only state in America where treated industrial and municipal wastewater cannot be discharged to a surface water body used downstream as a source of drinking water. It is legal in all 49 other states. For example, New Orleans, Louisiana takes its drinking water from the Mississippi River which receives discharges of many, many treated municipal and industrial wastewater discharges as well as agricultural runoff from the more than 20 states that are upstream of it. Should other states be required to adopt Connecticut's standard? Why
