Question
Chapter 10, Problem 1GST
a)
To determine
The average yearly rate of ice advance in the centre of the glacier with reference to the given diagram.
a)
Expert Solution
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)
Expert Solution
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)
Expert Solution
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.

Background/Synopsis
You are working for the administrative or government apparatus of a city. Good credentials have
resulted in you working in this position.
The top echelon of the city government changed a few years ago, but they did not replace many
staff. Nonetheless, the situation is such that the city is led by a corrupt mayor who has realized dded
that elections are approaching. Opinion polls suggest that a significant part of the electorate has
the environment as a major concern. Close associates of the mayor organized a focus group and
chose to investigate several initiatives which they felt might be possible to conduct in a relatively
short amount of time.
Jual pro
Metho
The administration wants several projects examined. You have been tasked with conducting a
cost benefit analysis on the construction of permeable pavements. The idea put forth is to replace
A2_Call city alleyways with permeable pavements as a means to better manage water resources.

I always find it interesting to consider the Earth's Hydrologic Cycle, our water in all of the different phases: solid ice, liquid water, and water vapor (a gas). In place number one for the majority of the World's water, we have the oceans. In place number two, we have ice. Neither one is available to us for drinking water at this point. Amazingly enough, in place number three is groundwater before lakes and streams. Water has led to many problems in the history of California, the United States, and even the world.

Outline of topic: Increased urbanization together with climate changes forces cities to find solutions for their simultaneous water shortage and flooding problems. The preservation of water resources needs sustainable urban water management strategies that combine ecological health maintenance with these priorities. This study investigates combined strategies that involve rainwater collection together with wastewater treatment and the deployment of green infrastructure consisting of urban wetlands alongside permeable pavements. The research aims to discover multi-purpose solutions that decrease flood dangers together with water shortages while maintaining ecological health for long-term urban water management success. The research investigates ways in which novel solutions assist cities to create…arrow_forward
