Do natural events like volcanic eruptions contribute to
chlorine in the stratosphere? - .....ANSWER ...✔✔ Yes,
chlorine can come from natural sources such as
volcanoes, but they are not the primary source
Ground-level ozone is what absorbs and reflects
harmful UV rays from the sun - .....ANSWER ...✔✔
False
Ozone in the stratosphere absorbs and reflects harmful
UV rays from the sun, not ground-level ozone. Ground-
level ozone is actually harmful for humans when inhaled.
In which of the ways does ozone depletion affect
humans? - .....ANSWER ...✔✔ Increased risk of skin
cancer; Increased risk of cataracts.
When ozone is depleted, there is not enough ozone
present to absorb and reflect harmful UV rays from the
sun
Is there evidence that refrigerants are in the
stratosphere? - .....ANSWER ...✔✔ Yes
Air samples taken from the stratosphere confirm that
refrigerants, such as CFCs and HCFCs, reach the
stratosphere, where they destroy ozone.
