These volcanoes pumped water vapor, ammonia, and carbon dioxide into the atmosphere around Earth. …
WebIn the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O 2), they split the molecule into two single oxygen atoms, known as atomic oxygen. A freed oxygen atom then combines with another oxygen molecule to form a molecule of ozone. WebWord of the ozone hole spread through news headlines like wildfire, as people began to realize the significance of a region in the stratosphere that most had never heard of before. Without the ozone layer Earth would be very different. Earth's gaseous envelope, the atmosphere, is made up of layers.
