Cays- they are formed when ocean currents transport loose sediments across a surface of a reef to a despositional node
Hey there!
Airplanes must be pressurized when flying at high altitudes so that the oxygen levels stay normal for us to breathe. The higher you go up, the thinner the air gets, which causes breathing problems for us humans.
Thank you!
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.
Four elements of civilization include division of labor commerce and trade technology.
<h3>
What is civilization?</h3>
- Any complex society that has developed a political state, social stratification, urbanization, and symbolic communication methods beyond naturally occurring spoken language is considered to be a civilization (namely, a writing system).
- Greece is frequently said to as the origin of Western culture and the birthplace of democracy. This is especially true of the Acropolis of Athens.
- Additional traits including centralization, the domestication of plant and animal species (including humans), labor specialization, culturally imprinted beliefs of progress, monumental architecture, taxation, societal reliance on agriculture, and expansionism are also closely linked to civilizations.
- In contrast to smaller, ostensibly less advanced cultures, "a civilization" has frequently been believed to be a bigger and "more advanced" culture.
