How does radiation affect the ozone layer?
The depletion of the ozone layer leads, on the average, to an increase in ground-level ultraviolet radiation, because ozone is an effective absorber of ultraviolet radiation. The Sun emits radiation over a wide range of energies, with about 2% in the form of high-energy, ultraviolet (UV) radiation.
What are the effects of ozone layer?
Ozone layer depletion causes increased UV radiation levels at the Earth’s surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.
Do waves create ozone?
Ozone is produced in the air by the crashing of the waves in the ocean and as such became a fashionable name for cafes and hotels that sprung up everywhere around the turn of the century.
Does radiation destroy the ozone layer?
Ozone molecules in the stratosphere are constantly being produced and destroyed by different types of UV radiation from the sun. Normally, the production and destruction is balanced, so the amount of ozone in the stratosphere at any given time is stable.
What is ozone layer How does ozone layer protect us?
The ozone layer acts as an invisible shield and protects us from harmful ultraviolet (UV) radiation from the sun. In particular, the ozone layer protects us from the UV radiation, known as UV-B, which causes sunburn.
What is ozone layer depletion causes and effects?
The main effect of ozone depletion is an increase in UV-B rays reaching the earth’s surface. Causes : chlorofluorocarbon (CFCs), halons, and other compounds deplete the ozone layer. CFCs and halons break down into chlorine and bromine which in turn destroy the ozone layer.
What are the causes and effect of ozone layer depletion?
Explanation: Ozone depletion is primarily caused by human activities. The main effect of ozone depletion is an increase in UV-B rays reaching the earth’s surface. Causes : chlorofluorocarbon (CFCs), halons, and other compounds deplete the ozone layer.
How does ozone layer protect us?
What does the ozone absorb?
The ozone layer in the stratosphere absorbs a portion of the radiation from the sun, preventing it from reaching the planet’s surface. Most importantly, it absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light from the sun (and sun lamps) that has several harmful effects.
Does the ocean produce ozone?
The ocean, a longtime reservoir for CFC-11, will become a source of the ozone-depleting chemical by middle of next century, a new MIT study finds. The world’s oceans are a vast repository for gases including ozone-depleting chlorofluorocarbons, or CFCs.
What does ozone layer do?
The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth’s surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.
