<span>An economic indicator shows the measurement to determine and
analyze the economic progress and performance of a country. Examples of this are consumer price index,
inflation, industrial production, bankruptcies, gross domestic product, retail
sales, stock market prices, money supply changes and unemployment rate. How these indicators perform depends on the
effectiveness of the policies and programs being implemented by the government’s
economic institutions. If these policies
help in the improvement of the country’s economic development then it will be
reflected in these indicators. Same can
be said if it is not effective.</span>
Answer:
B. atmosphere: because the ash blocked more radiation than normal, not allowing it to reach the surface
Explanation:
The volcanoes are one of the major factors that shape the climate on Earth. Their influence can be more moderate and gradual, or it can very big and abrupt. The large volcanic eruptions manage to cause changes in the global climate very quickly. The reason for this is that they have big influence on the atmosphere. By releasing lot of ashes and small particles into the atmosphere, a layer of them is formed around the Earth. This layer had greater albedo, thus it is reflecting the sunlight instead of letting it go through. This causes rapid drop in the global temperatures, and as was the case in 1815, it resulted in a year without summer. If the volcanic eruption is very big and comes from a super-volcano, than it can have much longer impact, lasting for decades or even centuries.

Describe the difference between revolution and a rotation, explain why each is important.
Revolution - Revolution is when the Earth revolves around the sun. This process takes 365 days/ 1 year.
Rotation - Rotation and revolution are both different. Rotation is when Earth is spinning on its own axis and also revolving around the sun. Rotation gives us day and night.
Why are they important?
Rotations gives us day and night which is 24 hours. Revolution gives us season. Earth's spins controls our live. We sleep at night and are awake in the days. Both of the spins are very vital to us.
Hope I helped (:
Have a great day!
