The evidence that the universe is flat is the tiny variations in cosmic backgrounds. The universe is flat, the universe is simply connected with the edges aren't glued together as in a torus and the universe contains finite mass and energy.
Answer:
The possibility of the universe expanding and thus being infinite can be cited as evidence that the universe is flat because an infinite plane is believed to have zero curvature.
Explanation:
- If an expanding object is given a curve in its course of expansion, it eventually ends up meeting itself at some point or the other.
- If something is believed to be 'ever-expanding', it can be broadly concluded that it has no curvature at all.
Answer:
The three large peninsulas extending off of Europe are the Iberian Peninsula, Italian Peninsula, and the Balkan Peninsula.
Explanation:
- The Europe continent is a 'peninsula of peninsulas'. Which means a bigger piece of land covered by 'water on three sides' and is constituted by smaller pieces of land which are also covered by 'water on three sides'.
- It is a peninsular landmass that is made up of other subsidiary peninsulas stretching out of the main peninsula.
- The European continent is covered by water on three sides both on the northern front and the southern front.
- It is covered by water on almost all the sides but is still connected to a larger piece of land.
- The three of the major peninsulas in Europe are the 'Iberian Peninsula', 'the Balkan Peninsula' and 'the Italian Peninsula' which are all on the southern side of the European continent.

Answer:
The length of time that a volcanic eruption impacts the climate is largely determined by whether the ash or gas reaches the stratosphere
Explanation:
A volcanic eruption releases gases and other particles in the atmosphere. The factor whether these released material reaches the stratosphere or not, determines whether that particular volcanic eruption will affect the climate or not.
The enormous output from the eruption gets released in the atmosphere. This output forms a permanent layer in the atmosphere over time and becomes a barrier to the sunlight reaching the earth.
The decrease in sunlight causes cooling effect thereby decreasing the temperature of the planet.
The time taken by the emission to reach the stratosphere determines the time taken by the emission to change the climate of the planet.
The gas that is the largest component of the atmosphere is oxygen. The correct option is B. In nature, nitrogen (N2), which accounts for about 78% of air, is the most prevalent gas. The second most prevalent gas after nitrogen (N2) is oxygen (O2).
Which gases are most important?
One of the most crucial gases to humans is oxygen. Due to the necessity of carbon dioxide for photosynthesis in plants, it is one of the most vital gases for all life on Earth.
The other main factor is that, in contrast to oxygen, nitrogen is much more stable in the atmosphere and plays a much smaller role in chemical reactions that take place there. As a result, it has accumulated in the atmosphere to a much greater extent than oxygen over geological time.
Thus, the ideal selection is option B.
