Basically, the moon is made up of similar ingredients as the earth because it is formed from the same remains of an impact that destroyed the earth. Among the more abundant elements known to be present on the moon’s surface include, silicates, which are anions that contain both silicon and oxygen. The same way they are in abundance on the moon is the same way they are in abundance on earth and make up approximately 90% of the earth’s crust
The global temperature records show the fluctuation of temperature from ocean to landraces and varying extremes. These have existed since the 1850 period when measured from the Pleistocene ice age by the use of various tools and techniques like the weather balloon radioscopy.
Tree ring and ice core data have shown a measuring record from 1000 to 2000 years of data, based on lake sediments, cave deposits and fossils records. The global mean surface temperatures have ranged for over 25 years of span with periods of little ice age and medieval warm periods.
World War I and II. These wars caused lots of economic growth and development because there was a pressure to create better inventions. Having better technology could mean the win or lose of a war. :D
