Answer:
b. stratigraphically alternating sequences of sandstones, conglomerates, and shales.
Explanation:
It is unlikely that one would find igneous rocks such as basalt and granite in fluvial environments. Coal is also not usually found in fluvial environments. Limestone prefers shallow and calm waters so would not be moved by water normally. This therefore invalidates options a, c, d, e and f.
For the hypothesis to be true, one would need to find conglomerates as these contain large clasts and are present in fluvial environments. Alternating sequences involving conglomerates and sandstones would indeed show that that some floods were able to carry large clasts.
Answer:
Option C. Is used to cool the drill bit and to flush rock cuttings up and out of the drill hole
Explanation:
Drill mud plays a vital role in the drilling process. Its addition into the well-bore does a lot in enhancing the drilling processes and activities.
Among other importance and function of the drill mud /fluid:
1. It is used to cool off the drill bit
2. It flushes rock cuttings out of the drill hole
3. High pressure control
4. Providing buoyancy
5. Lubrication
South Asia is a really difficult place to try and centralize the countries. A big problem are the large populations in the countries, with the likes of India, Pakistan, and Bangladesh all being in one of the most populated countries in the world, so centralizing them would mean that hundreds of millions of people will either live on the verge of existence (even worse than it is now), or will be moving towards the city where the centralization will be taking place, and there's no such place that can function properly if that amount of people flood in it. Another problem is that there's multiple cities that are very big, with millions of people living in them, and if centralization takes place, they will start to decline in every aspect, and that will cause huge problems of all sorts on national level.
Considering the information the information in Border 2012 to answer the questions below, we have the following:
1. 3 of the 15 pairs of sister cities along the U.S.-Mexico border include:
- Deming, New Mexico;
- Douglas, Arizona;
- Alpine, Texas.
2. Yes, I believe that the health of the environment in the border region and the health of the residents will improve because the program is designed and meant to improve the environmental conditions along the United States-Mexico border.
Also, the program is designed to be carried out by all the stakeholders involved, including the communities involved who brought most of the idea of the programs.
3. Both nations must work together to clean up the pollution because there is a thin line between the United States and Mexico border.
Some land borders between the two nations are interwoven. In such a situation, people and the effects of pollution in one nation can easily diffuse or move to another nation.
Thus, to eradicate environmental problems like pollution, both nations need to work together to get it done.
4. The two nations can work together to balance their interests and needs with the environment's health by taking the following actions:
- setting standards,
- making the right environmental policy decisions,
- properly monitoring the environmental programs on the border area,
- working with both nations' border Indian tribes to develop and;
- execute different policies to would yield desired results.
Hence, in this case, it is concluded that Border 2012 is a good bilateral initiative between the United States and Mexico governments.
