olga2289 [7]

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.

aleksandrvk [35]

The North Star appeared to move higher in the sky.

Answer: Option 3

<u>Explanation:</u>

North star is a special star found in the sky which is said to be fixed in the sky and does not move from it's place and the reason for this is that this star is very near to the axis of the planet Earth and is the only star that does not change it's position in relation to the rotation of earth. So since Albany is to the north of the New York city, the star will appear to move higher towards the north in the sky.
