Answer:
<em>Developing countries two major issues, of low incomes and eventually lower tax collections.</em>
Explanation:
Obstacle 1: Developing countries usually have a population with a low income. There are a lot of poor people, very few businesses are documented and there are very few well established larger corporations.
Obstacle 2: Lower income results in a low tax collection for the country. This means that the government is not able to meet its basic infrastructure resulting in underdeveloped health facilities and basic infrastructure.
In order to improve this, they look for either foreign direct investment into their country or take out loans from international banks to fund basic needs.
If done well, countries can escape from poverty. However if loans are mismanaged, countries can quickly find themselves burdened with rising debt and more poverty.
The changing ocean currents lead to climate cooling by bringing cooler breezes to places with higher climates. The cool breezes push the warm air out and leads to the drop of temperature

Answer: In some parts of the world, windblown dust and silt blanket the land. This layer of fine, mineral-rich material is called loess. Loess is mostly created by wind, but can also be formed by glaciers. When glaciers grind rocks to a fine powder, loess can form.
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.
