It is true that the ozone layer is being depleted. All the warming signs are true.
False. The main cause of the thinning of the ozone layer is the presence of halogen atoms in the stratosphere from man-madeHalocarbon refrigerants (CFCs, freons, halons).
It is true. Ozone is an allotrope of oxygen.
it does not cause the creation of the ozone.
False. Depletion of the ozone layer allows more harmful UV-B rays to reach Earth's surface, which can cause damage to plants and animals. UV-A rays are less harmful than UV-B rays and are not significantly affected by ozone depletion.
The ozone layer absorbs and scatters the majority of the Sun's harmful ultraviolet (UV) radiation before it reaches the Earth's surface. This helps to protect us from health issues like skin cancer, cataracts, and immune suppression that can be caused by UV exposure. Without the ozone layer, these harmful UV rays would reach the Earth's surface in much larger quantities, posing a significant threat to humans and other living organisms.
False it is. It is present in the stratosphere.
true
False. The main cause of the thinning of the ozone layer is the presence of halogen atoms in the stratosphere from man-madeHalocarbon refrigerants (CFCs, freons, halons).
It is true. Ozone is an allotrope of oxygen.
it does not cause the creation of the ozone.
True
CFC's are catalysts. They fasten the rate of reaction.
True, the absorption of UV rays by the ozone layer creates heat which forms the stratosphere, which gets warmer the higher you go.
False. In the stratosphere, where the ozone layer is located, temperatures actually increase with altitude. This warming occurs because ozone absorbs ultraviolet (UV) radiation from the sun, which heats the surrounding air. Therefore, as you ascend through the ozone layer, it generally gets warmer, not colder.
false
False
True AND False OR True evaluates to True. IT seems like it does not matter which is evaluated first as: (True AND False) OR True = False OR True = True True AND (False OR True) = True AND True = True But, it does matter as with False AND False OR True: (False AND False) OR True = False OR True = True False AND (False OR True) = False AND True = False and True OR False AND False: (True OR False) AND False = True AND False = False True OR (False AND False) = True OR False = True Evaluated left to right gives a different answer if the operators are reversed (as can be seen above), so AND and OR need an order of evaluation. AND can be replaced by multiply, OR by add, and BODMAS says multiply is evaluated before add; thus AND should be evaluated before OR - the C programming language follows this convention. This makes the original question: True AND False OR True = (True AND False) OR True = False OR True = True
