The correct answer is - They formed long ago, and erosion has beveled them to their present elevation.
The Appalachian Mountain Range is one of the oldest mountain ranges on the planet. They have formed in the Ordovician Period, around 480 million years ago. When they formed and were at their peak, the Appalachians were much larger and higher than what they are in the present. The reason for their decline in size is attributed to the erosion. The erosion is a process that removes the material from its original position. This process has been influencing, at different rates, the Appalachians for almost half a billion years. Even though the erosion is not a process that acts very quickly, when put the time that it influenced these mountains we will see that it managed to lower them significantly. That process continues in the present, and in the manner in which the continents are moving, there shouldn't be any force that will help lift up the Appalachians again, but instead they will continue to shrink until they are flattened in the distant future.
Farmer Wilcox should plant a windbreak or shelterbelt. There are plantations made up of one or more rows of trees to provide shelter from the wind and to prevent wind velocity near his farm.
Answer: Exactly the same way since the very begining of our existence?
Explanation: Uniformitarianism suggests that the processes that rule the Earth have always been the same.
The only thing that comes to my mind and that has something to do with the disaster of Chernobyl is that all the radioactive and hazardous activity somehow could have affected the structure of the soil. It´s not pretty clear, but in practical terms, I wouldn´t build another facility on at least 30 miles around Chernobyl or Pripyat.
‘Climate’ is an old idea, but an idea which retains tremendous power, versatility and utility in today’s world. For the Ancient Greeks, climate worked both as index and as agency , and this dual function has recurred throughout human cultural history and it works too in contemporary discourses about climate change. Climates change physically, but climates can also change ideologically. What climate means to different people in different places in different eras is not stable. If culture is concerned with how human meaning, symbolism and practice take on substantive and material forms, then studying climate through culture is likely to be a fruitful activity.
