Weekly Quiz Competition

Question 1
1 / -0

The atmosphere of the earth is heated by radiations which are mainly:

A
Radiated by the sun

B
Re-radiated by land

C
Re-radiated by water

D
Re-radiated by land and water

Solution

Earth's surface gets heated by the energy received from sun in short wave from, then earth itself becomes a radiating body and star radiating heat in long wave forms. This energy heats up the atmosphere from below and phenomenon is called "terrestrial radiation". The correct options is A
Question 2
1 / -0

The blanket of gases that surround the earth is called

A
Air

B
Atmosphere

C
Lithosphere

D
Biosphere

Solution
Question 3
1 / -0

Which of the following is not correctly matched?

A
Water pollution- using synthesis detergents for ashing clothes

B
Photochemical smog- releasing gases produced by automobiles and factories

C
Damaging ozone layer- using $$CFCs$$

D
Acid rain- releasing pesticides and fertilizers in water

Solution

Acid rain is caused by releasing gases to atmosphere after burning waste material containing sulphur. Hence option (D) is the answer.
Question 4
1 / -0

An increase in $$ CO_{2}$$ concentration in the atmosphere will result in :

A
Adverse effects of natural vegetation

B
Global warming

C
Temperature decrease in global atmosphere

D
Genetic disorders in plants and animals

Solution

Rising carbon dioxide concentrations will increase plant growth. More rapid leaf area development and more total leaf area could translate into more transpiration. Rising carbon dioxide concentrations will decrease leaf stomatal conductance to water vapor. This effect could reduce transpiration.
Question 5
1 / -0

Acid rain occur due to atmospheric pollution of .;

A
$$ SO_{2}$$

B
$$ NH_{3}$$

C
$$ CO_{2}$$

D
$$ N_{2} O$$

Solution

sulphuer di oxide
Question 6
1 / -0

Pollution can be controlled by :

A
Sewage treatment

B
Checking atomic blasts

C
Manufacturing electrically operated vehicles

D
All the above

Solution

Sewage treatment, Checking atomic blasts
Manufacturing electrically operated vehicles

so all are correct
Question 7
1 / -0

The gaseous envelope around the earth is known as atmosphere . The lowest layer of this is extended upto 10 km from sea level, this layer is ...

A
Stratosphere

B
Troposphere

C
Mesosphere

D
Hydrosphere

Solution

The gaseous envelope around the earth is known as atmosphere . The lowest layer of this is extended upto 10 km from sea level, this layer is called troposphere
Question 8
1 / -0

Recent reports of acid rains industrial cities are due to the effect of atmospheric pollution by :

A
Excessive release of $$ NO_{2} and SO_{2} $$ by burning of fossils fuels

B
Excessive release of $$ CO_{2} $$ by burning of fuel like wood and charcoal , cutting of forest and increased animal population

C
Excessive release $$ NH_{3} $$ by industrial plants and coal gas

D
Excessive release CO in atmosphere by incomplete combustion of cock , charcoal and other carbonaceous fuels in pancity of oxygen

Solution

release of NO2 and SO2 in factury as a burning of fossils fuels
Question 9
1 / -0

What is the correct sequence of atmosphere layers starting from earth ?

A
Stratosphere troposphere , mesosphere , thermosphere

B
troposphere, Stratosphere , mesosphere , thermosphere

C
mesosphere , t troposphere , Stratosphere , thermosphere

D
Thermosphere , mesosphere Stratosphere troposphere

Solution

troposphere, Stratosphere , mesosphere , thermosphere
Question 10
1 / -0

Which of the following statements is wrong ?

A
Polar stratosphere clouds (PSCs) are clouds formed over Antarctica

B
Acid rain dissolved heavy metals such as Cu , Pb , Hg and Al from soil , rocks and sediments.

C
$$ H_{2}SO_{4}$$ is major contributor to acid rain, $$HNO_{3}$$ ranks second and HCl third in this respects

D
Fishes grows as well in warm as in cold water

Solution

Actually can grow in both, cold and warm water. However, too cold and hot will unbearable for the fishes. Also, sudden change in temperature can affect not only the fishes, any type of aquatic fishes and animals.

D is wrong statement
