Recently we started to discuss the building and breaking down of mountains. Living in Sacramento we do not get to see actual mountains. However I have driven all up and down the westside of this country and I have seen the Rockies, Sierras, and Grand Canyon. A lot of the Rockies is sedimentary rock, and the Sierra Nevada's are Limestone. This building up process of these mountain ranges has taken years, and since they are still young and the plates are still constantly moving, they will continue to grow higher and higher. But due to the active movement of our Pacific plate, there are extreme differences in California. Death Valley ( the lowest point in the United States of America) and Mount Whitney ( the highest point in the United States) are literally only about one hundred and fifty miles apart.
This active movement might be another reason our weather patterns have slowly changed. Along with global warming, these two factors have to be the two biggest reasons why we are still having seventy five degree weather in Northern California, in December. As the plates move further north, so will the weather patterns, but since the north is getting warmer, so will we.
