Answer:
According to the former chief environment officer of the state environment department, Calcutta is blessed ecologically because it has, “the Ganga flowing beside its western end, traditionally huge groundwater reserve and wide wetlands area in its eastern fringe which naturally treats its waste water and turns that as raw water for fishery and agriculture.” Despite these advantages the city is increasingly running into trouble.
Officially 15% of core Calcutta’s water come from groundwater sources and rest from surface water. With the entire city being supplied water through pipelines. In reality up to 25% to 30% of the water used in households is groundwater.
Despite having water connections, rich families living in newly constructed multi-story apartment blocks pump their own water. They say that they do not have much faith on the quality of water supplied by civic bodies. The situation is even worse in smaller cities within Calcutta Metropolitan Area where the access to surface water is much less.
As a consequence of this groundwater levels have plummeted in various parts of the city. The people of Calcutta had carried out a detailed assessment of groundwater status in the city some years back and found that there had been sharp decline especially in central to south Calcutta as well as along EM Bypass where most high-rises have come up in recent years. So what the people of Calcutta were doing wouldn't help now because they are running out of water faster than you can count.
Calcutta officially has about 17,000 stand posts (as water hydrants are referred to in the city), 12,000 hand tube wells and around 2,500 large tube wells mainly catering to multi-story buildings, but the actual figures are far higher. In the same vein, although officially commercial establishments and industries account for around one-fifth of the city’s water, the actual consumption is significantly higher.
Supplying drinking water has become a big business in and around Calcutta, especially in areas with unsafe groundwater. For example, Madhusudhankati is a small hamlet at the northern fringe of Calcutta Metropolitan Area where groundwater is contaminated with arsenic. In the village nearly 200 families pay ten rupees every day to buy 20 litres of safe drinking water provided by non-profit Sulabh International. Rates are much higher in other areas where private companies operate.
The drinking water supply also gets contaminated by leaking sewerage pipes. Industrial pollutants including heavy metals also leak into groundwater supplies. There was an effort from the state pollution control board to ensure that industries treat effluent before disposing it into the sewer line but they have to accept that virtually nothing has been done on the ground.
With all these problems, the city is running towards an imminent water crisis. There is a limit to supply of treated surface water if you do not introduce water charges and minimise water waste. With increasing demand the pressure will be more on groundwater, which in turn will further affect the quantity and quality of groundwater especially in context to continually decreasing water recharge due to increasing concretization, there is no doubt, despite traditionally having good water reserves Calcutta are entering into an era of water starvation in city

Write a congruence statement for any figures that can be proved congruent.
Answer:
From the triangles, I think the congruence statement would be that of the ASA theorem. Triangle AWC is congruent to triangle RWC by virtue of the Angle-Side-Angle theorem. hope I helped ;)
Explanation:
21. The triangle EDG is concurrent to EFG by ASA concurrency.
23. The value of x is 55°.
What is triangle?
Simple polygons with three sides and three internal angles make up triangles. One of the fundamental geometric shapes, it is represented by the symbol and consists of three connected vertices.
One of the fundamental shapes in geometry is represented by the symbol Δ and consists of three connected vertices.
Three straight lines coming together create a triangle. There are three sides and three corners on every triangle (angles). A triangle's vertex is the intersection of two of its sides. Any one of a triangle's three sides can serve as its base, however typically the bottom side is used.
The triangle EDG is concurrent to EFG because,
∠ D = ∠ F = 90°
FG = DE
∠ GED = ∠ FGE
Thus, they are concurrent by Angle side angle concurrency.
23. Calculate The value of x as shown below,
90 + 35 + x = 180 (Sum of interior angles of a triangle is 180°)
x = 180 - 125
x = 55°

Even though you are getting closer to the sun as you ascend into the troposphere, why does the temperature drop?
the lower atmosphere is heated by the ground
warm air stays below cold air
the troposphere is a stable layer
ozone blocks the sunlight
Answer:
hope it's the right answer:warm air stays below cold air
Explanation:
warm air stays below cold air:the troposphere is heated from the ground, so temperature decreases with altitude. Because warm air rises and cool air sinks.
the lower atmosphere is heated by the ground:*the troposphere is heated from the ground*
the troposphere is a stable layer:*the troposphere is unstable*
ozone blocks the sunlight:*in the stratosphere, temperature increases with altitude.The stratosphere contains the ozone layer, which protects the planet from the Sun’s harmful UV radiation*

1. Canada is located at a much higher latitude than Mexico. How does climate or
temperature change as latitude increases?
Answer:
Thanks for the question,
Due to the latitude and and distance from the equator the temperatures drop the further in a region,i.e. the equator because of the curvature of the world. In areas nearer to the poles, daylight has a larger space of atmosphere to experience and also the sun is at a lower angle within the sky.
In case of Canada and Mexico, Mexico lies near the equator and the sunlight directly hits the surface and therefore the climate and temperature in Mexico is constant and tropical. But, when we comes to Canada the latitudes increases and the temperature decreases due to the inconstant amount of sunlight. (Please check the attached Maps below which explains the latitude-temperature and latitude-climate effects)
Hope it helps!<3
Answer:
IS WITH EXPLANITION
Explanation:
latitude affects climate due to the rays of the sun as Mexico is slightly in the Torrid zone and Canada is in the North temperate zone so it is colder than Mexico thus proving latitude increase can effect climate

Just as climate has affected the settlement and agricultural activities of humans, likewise, humans have extensively modified the physical environment. Such modifications have been facilitated by globalization and urbanization. Human action such as the operation of industrial plants and power generating facilities has increased acid precipitation. Acid rain has the potential to damage forests, kill fish, and damage lakes. Excessive use of water is depleting ground water systems and creating water resource shortages.
1. Reset the map.
2. Select Water Resources Vulnerability. Select Acid Rain (U.S) and Split map window.
Compare the two maps and determine which statement is true.
A. Both acid rain and water resource vulnerability are extremely high for the Midwest.
B. Whereas the Southwest generally has extremely high water resource vulnerability, acid rain is a major issue on the East Coast.
C. Both acid rain and water resource vulnerability are extremely high for much of the East Coast.
D. Both acid rain and water resource vulnerability remain an issue for much of the Southwest
E. Whereas the East Coast generally has extremely high water resource vulnerability, acid rain is a major issue in the Southwest.
The statement which is true is that, "Whereas the Southwest region in U.S. generally has extremely high water resource vulnerability, acid rain is a major issue on the East Coast."
What do you mean by water resource vulnerability?The water resource vulnerability is defined as the tendency of water resource systems to break down because of the external influences. Vulnerability of water resources includes two aspects- sensitivity and adaptability of water resource systems to external driving factors.
The water resource vulnerability includes vulnerability of water quality and quantity. Thus, because of the climate change and human activities, human society is facing water resources shortage, frequent natural calamities, and a series of problems which leads to the increase in the vulnerability of water resource systems.
What is acid rain?Acid rain is a form of precipitation which is unusually acidic, with acidic components such as sulfuric or nitric acid which falls to the ground from the atmosphere in wet or dry forms. This includes- rain, hail, snow, fog, or even dust that is acidic.
Which part of the U.S. is most affected by water resource vulnerability?
The part of the United States which is most affected by water resource vulnerability is the Southwestern region of United States. This region stemmed mainly from consumptive uses whereas the vulnerability in watersheds of the southern US was due to changes in flooding, water quality issues, and other uses.
Which part of the U.S. is most affected by acid rain?The region of the United States which is most affected and harmed by acid rain is the East Coast, including the Appalachian Mountains and the Northeast Some.
Thus, acid rain occurs naturally, but when sulfur dioxide and nitrogen oxide emissions from smokestacks combine with rain they tend to make sulfuric and nitric acid in amounts which harm the environment.
