Q1.
Ozone (O₃) is composed of how many atoms of oxygen?
Two
Three
Four
Five
Show answer
Answer: B. Three
Ozone (O₃) is a triatomic molecule composed of three oxygen atoms, forming a bent molecular structure.
Q2.
What color is ozone gas in its natural state?
Light blue
Dark blue
Colorless
Green
Show answer
Answer: B. Dark blue
Ozone is a dark blue colored gaseous molecule in its natural state, which distinguishes it from colorless oxygen.
Q3.
Approximately what percentage of total ozone is found in the stratosphere?
70%
80%
90%
95%
Show answer
Answer: C. 90%
About 90% of Earth's total ozone is found in the stratosphere, forming the protective ozone layer that shields us from harmful UV radiation.
Q4.
At what altitude range is the stratospheric ozone layer primarily located?
5-15 km
15-35 km
35-50 km
50-80 km
Show answer
Answer: B. 15-35 km
The stratospheric ozone layer is primarily located between 15-35 kilometers above the Earth's surface, with maximum concentration around 20-25 km.
Q5.
Which atmospheric layer contains the ozone layer that protects Earth from harmful UV radiation?
Troposphere
Stratosphere
Mesosphere
Thermosphere
Show answer
Answer: B. Stratosphere
The protective ozone layer is located in the stratosphere, the second layer of Earth's atmosphere, where it absorbs harmful UV-B and UV-C radiation.
Q6.
What is the primary difference between 'good ozone' and 'bad ozone'?
Chemical composition
Location in atmosphere
Molecular structure
Temperature
Show answer
Answer: B. Location in atmosphere
The difference between good and bad ozone is their location: good ozone is in the stratosphere protecting us from UV rays, while bad ozone is in the troposphere causing pollution.
Q7.
Which of the following best describes the molecular structure of ozone?
Linear molecule
Bent/angular molecule
Tetrahedral molecule
Octahedral molecule
Show answer
Answer: B. Bent/angular molecule
Ozone has a bent or angular molecular structure due to the lone pair of electrons on the central oxygen atom, giving it a V-shaped geometry.
Q8.
The ozone layer in the stratosphere is also known as:
Ozonosphere
Ionosphere
Magnetosphere
Chromosphere
Show answer
Answer: A. Ozonosphere
The ozone layer in the stratosphere is also called the ozonosphere, which is the region of maximum ozone concentration in Earth's atmosphere.
Q9.
What is the primary function of stratospheric ozone for life on Earth?
Provides oxygen for breathing
Controls weather patterns
Filters harmful UV radiation
Maintains atmospheric pressure
Show answer
Answer: C. Filters harmful UV radiation
The primary function of stratospheric ozone is to filter and absorb harmful ultraviolet radiation from the sun, protecting life on Earth from DNA damage and skin cancer.
Q10.
In which layer of the atmosphere would 'bad ozone' primarily be found?
Troposphere
Stratosphere
Mesosphere
Thermosphere
Show answer
Answer: A. Troposphere
Bad ozone is primarily found in the troposphere (ground level), where it acts as a pollutant and contributes to smog formation and respiratory problems.
