The answer is D, noble gases are stable.
Answer: Gneiss
Explanation: Gneiss is a metamorphic rock formed from shale at very high temperature and pressure condition. They exhibit a preferred alignment or orientation of platy minerals called foliation. They are coarse grained and exhibit gneissose banding. They are formed from highest grade regional metamorphism with temperature between 450 - 600 degree celcius and pressure between 800 - 1000 mega pascal. They generally occur in cores of fold mountain belts where mountain ranges have been eroded.
Explanation:
This has put huge stresses on a range of natural systems, including the atmosphere[3],. The increase in the use of fossil fuels has been even greater than the increase in industrial activity. ... The characteristics of the systems that have led to these changes also make the problems hard to address.
Answer:
There have been three small railways, but none became part of the public transport network. The main reasons for the lack of railways are the small population, competition with automobile traffic, and the harsh environment.
Explanation:
Answer:
The climate and vegetation of Latin America have made many people move out, certain areas to be highly populated while some lack population, with the way of life, is very vibrant, with a lot of interaction, music, and spending time outside.
Explanation:
The majority of Latin America has tropical types of climate, with smaller patches having Mediterranean, temperate, or mountainous climates. Being dominated by tropical climates, this region is not the best when it comes to equal distribution of population, as the tropical rainforests have too much vegetation, heat, humidity, and precipitation, while the deserts and semi-deserts lack vegetation and water resources.
This has led to people being concentrated heavily along the coastlines, but also at relatively flat area high on the mountains and plateaus near the Equator. A lot of people have decided to migrate to other regions though, as their environment has not been the best for living. The ways of life can be said that are similar in many ways to the cultures from the Mediterranean region, vibrant, loud, lot of interaction and music, spending a lot of time outside.
