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

Answers

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*

In 2014, Russia occupied and subsequently annexed this portion of the

A. Italian Peninsula
B. Armenian Peninsula
C. Crimean Peninsula
D. Balkan Peninsula

Answers

Answer:

the answer is Crimean peninsula

Answer:

Crimean Peninsula in Ukraine  

Explanation:

Russian Expansion and Political Interference

After the Cold War ended, the United States and its European allies began to view Russia as less of a security concern. Instead, they looked for ways to cooperate politically and economically with the former adversary. This period of relative peace was broken in 2014 when Russian military forces moved into and occupied several eastern Ukrainian provinces and the region of Crimea. Russia has taken on a more aggressive role in the world, largely under the leadership of Vladimir Putin.

Putin, a former KGB foreign intelligence officer, rose to power and became prime minister and president of Russia. Putin has used his power to increase Russia's economy and has sought to regain the former glory and power of the Soviet Union. The standard of living has risen under his regime, and he is thought to be widely popular. However, there's also a question as to how reliable Russian elections and favorability ratings are. Free speech continues to be limited in Russia, and protests are discouraged through increased fines and even prison time. Corruption has become more widespread, as well. Russia spends proportionately more on its military than the United States. Cyber-warfare and espionage form one of the nation's most effective means of attack. The FBI has confirmed that Russia was responsible for intervening in the US 2016 election. In 2020, President Putin ordered amendments to the Russian constitution that would allow him to remain in power past term limits until 2036, signaling that Putin's Russia will continue to be a force to resolve.

Answer:

Explanation:

In a business cycle, a contraction occurs when:
O A. aperiod of economic growth reaches its highest point.
B. the economy begins to show growth in key economic indicators.
O C. the economy slows down following a period of growth.
O D. a period of economic decline reaches its lowest point.

Answers

I think that it B but I’m not 100 percent sure

In a business cycle, a contraction occurs when the economy begins to show growth in key economic indicators. Thus, option (b) is correct.

At this point, the market is experiencing an excess of supply. Prices usually fall. All positive economic indices, such as revenue, output, wages, and so on, begin to collapse as a result. This stage of the business cycle is referred to as contraction or recession. An economic contraction is the downward slope of the business cycle towards a trough. In economics, contraction refers to a stage of the business cycle wherein the economy itself is in decline.

Therefore, option (b) is correct.

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.

Answers

Just a patreob will make it come true

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.

Hence, option B is correct.
