Answer:

Quaternary period

Explanation:

The last Ice Age on Earth occurred during the Quaternary period. This Ice Age only ended around 10,000 years BC, so very recently. During this period, big portions of the Earth were under ice, with approximately half of North America, as well as half of Eurasia being covered in ice. The mountains around the globe too were covered in glaciers. Because there was so much water trapped in the ice sheets and glaciers, the sea levels were much lower, which opened up lot of land-bridges between the islands and continents, which turned out to be crucial for the human migrations around the globe.

This passage is mainly about
N76 [4]

Answer:

This passage is mainly about asteroids striking Earth.

Explanation:

The presented passage is mostly focusing on asteroids striking Earth. It is something that has been happening since Earth has formed, and it will happen in the future as well. The vast majority of the asteroids don't really have any impact on Earth, but some have an impact that is devastating and long-lasting.

In the earlier stages of Earth, many more asteroids were falling on the surface, and the main reason for that has been the lack of atmosphere or a very thin atmosphere. As the atmosphere started to take shape and became similar to what is nowadays, the asteroid impacts decreased significantly because the atmosphere was managing to burn them and break them apart. This is not possible with all asteroids though, as some are so big and fall under an angle where the atmosphere doesn't really have any impact on them so when they fall on the surface they are able to cause sudden climatic changes, mass devastation, and mass extinction of species. Such an asteroid will be in a direction to hit Earth in the future for sure, the question remains will humans with their technology be able to prevent an impact or not.

Can you think of any problems that could come from using only 15 years of data to predict trends for the next 100 years? Explain
pentagon [3]

Explanation:

A major problem with using 15 years of data to predict 100 years of data is that the 15 years could have been setting a trend, then level off.

For example, if the 15 years of data was a graph, and it was going up every year, then what if 20 years into the 100 years it stops going up? Then that means the data was invalid because there wasn't enough to base any trends off of.

You can prevent this from happening by extending the collection time of data and to reduce the amount of time that the data will be used to predict.

Hope this helps!
