The stratospheric ozone layer is Earth’s “sunscreen” –
protecting living things from too much ultraviolet radiation from the sun
. The emission of ozone depleting substances has been damaging the ozone layer.
What is the function of the stratospheric ozone layer 1 point?
Ozone in the stratosphere (Good ozone).
Stratospheric ozone is considered good for humans and other life forms because it
absorbs ultraviolet (UV) radiation from the Sun
(see Figure Q2- 1). If not absorbed, high energy UV radiation would reach Earth’s surface in amounts that are harmful to a variety of life forms.
What is the function of the stratospheric ozone layer quizlet?
What is the purpose of the ozone layer?
To stop excessive amounts of ultraviolet radiation reaching the Earth’s surface
. It absorbs the UV rays to prevent them from reaching the ground.
What is the main function of ozone?
The main function of the ozone layer is
to absorb the Sun’s ultraviolet radiation
, hence protecting the Earth from its harmful effects.
What is the most important function of ozone?
Ozone
protects the Earth from harmful ultraviolet (UV) rays from the Sun
. Without the Ozone layer in the atmosphere, life on Earth would be very difficult.
Why should we care about ozone quizlet?
Ozone is a form of oxygen that contains three oxygen atoms instead of the usual two. … Why is the ozone layer important?
This layer acts as a filter to prevent too much of the harmful ultraviolet light in sunlight from reaching earth
.
What contributes to the ozone hole?
Ozone depletion occurs when
chlorofluorocarbons (CFCs) and halons
—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). … CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone’s ultraviolet radiation-absorbing capacity.
What is the main impact of ozone depletion?
Ozone layer depletion increases
the amount of UVB that reaches the Earth’s surface
. Laboratory and epidemiological studies demonstrate that UVB causes non-melanoma skin cancer and plays a major role in malignant melanoma development.
What is the importance function of ozone layer Class 9?
The importance of ozone is defined by the fact that
it protects the earth from harmful ultraviolet rays from the sun
. The ozone layer is found in the upper regions of the stratosphere where it protects the earth from the harmful ultraviolet rays of the sun. These radiations can cause skin cancer in humans.
What is the main function of ozone in upper atmosphere?
The Ozone layer at the upper atmosphere perform the function of
absorbing the harmful ultra violet (UV) rays coming from sun and prevents them from reaching the earth
. These UV rays cause harmful effects to humans, animals and plants.
What important function does ozone perform at higher level of atmosphere?
a) The Ozone layer at the upper atmosphere perform the function of
absorbing the harmful ultraviolet (UV) rays which are coming from the sun
and prevents them from reaching the earth.
What are the two types of ozone?
Ozone or “O3” is a colorless gas composed of three atoms of oxygen (O3). There are two types of ozone,
both “good” ozone and “bad” ozone
.
What is the importance of ozone day?
World Ozone Day is observed on September 16, every year. It is celebrated
to spread awareness among people about the depletion of the Ozone Layer and search for possible solutions to preserve it
. On this day, people from all over the world are expected to join the Montreal protocol to join the talks and seminars.
Is ozone good or bad?
Stratospheric ozone is
“good”
because it protects living things from ultraviolet radiation from the sun. Ground-level ozone, the topic of this website, is “bad” because it can trigger a variety of health problems, particularly for children, the elderly, and people of all ages who have lung diseases such as asthma.
Why is ozone found and why is it important quizlet?
Ozone layer is in the stratosphere about 20-30 km above Earths surface.
Provides protective layer = acts as a shield absorbing around 90% of UV rays
. High UV levels also slow photosynthesis in plants.
How is good stratospheric ozone formed?
Stratospheric ozone is formed
naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2)
. The “ozone layer,” approximately 6 through 30 miles above the Earth’s surface, reduces the amount of harmful UV radiation reaching the Earth’s surface.
