Answer:
The best answer to the question: The greenhouse effect is driven by the fact that greenhouse gases are:___, would be: Good absorbers of radiation at all wavelengths.
Explanation:
Under normal circumstances, the Earth receives energy from the sun and also produces a bit of its own energy. The energy that arrives from the sun is usually known as shortwave radiation, while the energy that is both absorbed by the Earth´s atmosphere, and the energy produced by Earth itself, becomes part of what is known as the longwave radiation. Greenhouse gases, like water vapor, carbon dioxide and methane trap both longwave and shortwave radiation, which should usually be expelled to a certain extent towards space, and maintain them trapped inside the atmosphere. This bouncing effect between the shield created by the gases and the lower atmosphere, should normally be controlled by the amount of atoms of gases in the higher atmosphere. However, in the greenhouse effect, what is happening is that the amount of gases is too high, and therefore they are trapping most of the radiation, both longwave and shortwave, and keeping it in, allowing the climate to warm up.

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.
