What is ozone

Ozone is created in the atmosphere when the sun's rays split oxygen molecules into single atoms. These atoms combine with nearby oxygen to form a three-oxygen molecule, called ozone. Even as it's being made, ozone is also destroyed by sunlight and reactions involving natural compounds that contain chlorine, nitrogen, and hydrogen. Most of the earth's ozone is contained in the stratosphere, a layer of the atmosphere 10–40 km above the surface of the earth. The amount of ozone in the stratosphere is fairly constant when viewed globally. However, it changes throughout the year and from one place to another. Most of the world's ozone is created over the Tropics, and is then pushed by stratospheric winds over the rest of the planet. For more info visit: https://www.youtube.com/theopenbook

The Middle Age

The Middle Age The fall of the Roman Empire marked the beginning of a new age in the history of Europe and most historians refer to it as the Dark Ages or the Middle Age. The name Dark Age was given by the Italian scholar and poet Petrarch as during this time he felt Latin literature and art were declining. This has come under question as the name is used to denote the period from5th to 10th centuries where there were intermittent periods of intellectual advance and periods of lull. Today it is considered derogatory to say Dark Age. For more info visit: https://www.youtube.com/theopenbook
