atmosphere

Question 1

is a layer of gases that
surrounds the Earth. The atmosphere is
made up of different gases. It is composed of
a mixture of different gases, including
nitrogen (about 78%), oxygen (about 21%),
argon (about 0.93%), carbon dioxide, and
trace amounts of other gases such as water
vapor, methane,

Answer 1

ATMOSPHERE

Question 2

5 layers of the atmosphere from innerost to outermost

Answer 2

Troposphere
Stratosphere
Mesosphere
Thermosphere
Exosphere

Question 3

This is the layer closest to the Earth’s surface and
contains the majority of the atmosphere’s mass. Weather
events, such as clouds, precipitation, and storms, occur in
the troposphere. Temperature generally decreases with
altitude.

Answer 3

Troposphere

Question 4

is known for the presence of the
ozone layer, which absorbs and protects against the majority of the sun’s harmful ultraviolet (UV) radiation. Unlike the troposphere, temperature increases with altitude in this layer. Contains 80% of the total mass of the atmosphere.

Answer 4

Stratosphere

Question 5

is where most meteorites burn up
upon entering the Earth’s atmosphere. Temperatures start decreasing again with altitude in this layer.

Answer 5

Mesosphere

Question 6

is characterized by a significant
increase in temperature due to the absorption of solar radiation. However, despite the high temperatures, the low density of particles in this layer means that it would not feel hot to a human. The International Space Station orbits within the lower

Answer 6

Thermosphere

Question 7

thermosphere is due to two occurrences

Answer 7

Ionosphere
Auroras

Question 8

is a region within the Earth’s atmosphere that
contains a high concentration of ions and free electrons.

Answer 8

Ionosphere

Question 9

Composed of ionized particles, primarily ions and free electrons.
Solar radiation, especially in the form of ultraviolet (UV) light, is
responsible for ionizing the gas molecules in this region.

Answer 9

Ionosphere

Question 10

The ionosphere is involved in the formation of auroras,
such as the northern lights (aurora borealis) and southern lights
(aurora australis). Solar wind particles interact with the ionosphere,
causing the release of energy in the form of light.

Answer 10

Auroras:

Question 11

is the outermost layer of the Earth’s
atmosphere, gradually transitioning into outer space. It has
extremely low density, and the few particles present can escape
into space. Satellites and other objects in orbit are found in this
layer.

Answer 11

Exosphere

Question 12

4 (Play crucial roles in supporting and sustaining life on Earth)

Answer 12

Oxygen and Respiration
Carbon Dioxide and Photosynthesis
Climate Regulation
Protective Layer

Question 13

it is when The atmosphere contains
oxygen, which is essential for
the respiration of many
organisms, including humans.
Organisms extract oxygen from
the air to support their
metabolic processes.

Answer 13

Oxygen and Respiration

Question 14

it is when Plants and certain microorganisms utilize
carbon dioxide from the atmosphere
during photosynthesis, converting it into
oxygen and organic compounds. This
process is vital for the production of food
and the maintenance of atmospheric oxygen levels.

Answer 14

Carbon Dioxide and Photosynthesis

Question 15

it is when The atmosphere plays a critical
role in regulating Earth’s
temperature through the
greenhouse effect. It helps
maintain a suitable climate for
diverse forms of life.

Answer 15

Climate Regulation

Question 16

it is when The atmosphere acts as a
protective shield by absorbing and
scattering solar radiation, reducing
the intensity of harmful ultraviolet
(UV) rays. This protection is crucial
for preventing damage to living organisms.

Answer 16

Protective Layer

Question 18

6

Negative Effects on Atmosphere

Answer 18

Air Pollution

Greenhouse Gas Emissions

Ozone Depletion

Acid Rain

Loss of Biodiversity

Global Warming and Climate Change

Question 19

it is the contamination of the indoor or
outdoor environment by any
chemical, physical or biological
agent that modifies the natural
characteristics of the atmosphere.
Household combustion devices,
motor vehicles, industrial facilities
and forest fires are common sources

of air pollution.

Answer 19

Air Pollution

Question 20

it is the Carbon Dioxide (CO2): The burning of fossil
fuels for energy and deforestation contribute
to elevated levels of carbon dioxide in the atmosphere.

Methane (CH4) and Nitrous Oxide (N2O):
Agricultural practices, livestock, and certain
industrial activities release methane and
nitrous oxide, potent greenhouse gases that
contribute to the greenhouse effect and global warming.

Answer 20

Greenhouse Gas Emissions

Question 21

it is the Chlorofluorocarbons (CFCs) and Halons:
These human-made compounds, once
widely used in refrigeration, air conditioning,
and aerosol propellants, have been major
contributors to the depletion of the ozone
layer. The thinning of the ozone layer allows
more harmful ultraviolet (UV) radiation to
reach the Earth’s surface, posing risks to
human health and ecosystems.

Answer 21

Ozone Depletion

Question 22

it is the Sulfur Dioxide (SO2) and Nitrogen Oxides
(NOx): Emissions from industrial processes
and combustion of fossil fuels release
sulfur dioxide and nitrogen oxides into
the atmosphere. These pollutants can
lead to the formation of acid rain, which
has detrimental effects on soil, water
bodies, and vegetation.

Answer 22

Acid Rain

Question 23

it is the Air pollution and climate
change can impact
ecosystems and lead to the
loss of biodiversity. Changes
in temperature, precipitation
patterns, and the distribution
of plant and animal species
can disrupt ecological balance.

Answer 23

Loss of Biodiversity

Question 24

it is the Temperature Rise: The
accumulation of greenhouse
gases in the atmosphere
contributes to global warming,
leading to changes in
temperature patterns, sea level
rise, and more frequent and
intense extreme weather events.

Answer 24

Global Warming and Climate Change
