Environment and Its Components Quiz

Conceptual Components of the Environment

• Hydrosphere: Includes all water bodies and is a crucial transporter of matter.
• Atmosphere: Acts as a transporter of matter through wind and air currents.
• Biosphere: Organisms within the biosphere play a role in the movement of matter through processes like photosynthesis and decomposition.

Thermosphere

• The thermosphere is known for the ionosphere, a layer of charged particles.

Environmental Spheres with Limited Storage Capacity

• Atmosphere: The atmosphere has the least ability to store matter in comparison to the hydrosphere, lithosphere, and biosphere.

Development Activities Impacting the Hydrosphere

• Pollution: Industrial and agricultural activities introduce pollutants into water bodies, affecting water quality and aquatic life.
• Damming: Construction of dams alters water flow and sedimentation patterns, impacting ecosystems downstream.

Stratosphere

• The temperature increases with altitude in the stratosphere, not decreases.

Atmospheric Layers

• Exosphere
• Thermosphere
• Mesosphere
• Stratosphere
• Troposphere

Ecology

• The study of living organisms with the environment is known as ecology.

Atmospheric Composition

• Nitrogen: Highest percentage of air.

Particulate Pollutants

• Carbon dioxide is not a particulate pollutant, but rather a gaseous pollutant.

Secondary Pollutants

• Ozone is an example of a secondary pollutant, formed from reactions between primary pollutants like nitrogen oxides and volatile organic compounds.

Definition of Environment

• The term "environment" encompasses everything surrounding us, including living and non-living components.

Jet Plane Flight

• The stratosphere provides a suitable environment for jet plane flight due to its stable atmospheric conditions.

Earth's Surface Coverage

• Water covers 71% of the earth's surface.

Sulphur Dioxide Source

• Burning of fossil fuels is a major source of sulphur dioxide.

Taj Mahal Pollution

• The Taj Mahal is being affected by acid rain caused by air pollution.

Most Polluted River

• The Ganges River in India is considered one of the most polluted rivers in the world.

Air Pollution Effects

• Air pollution can cause respiratory issues, cardiovascular diseases, and other health problems.

Greenhouse Gas

• Carbon dioxide is a significant greenhouse gas.

Nitrogen Percentage

• Nitrogen constitutes 78% of the atmosphere.

Carbon Monoxide Pollution

• Carbon monoxide is a pollutant because it reduces oxygen-carrying capacity in the blood, leading to health problems.

Naturally Occurring Greenhouse Gas

• CFCs (chlorofluorocarbons) are not naturally occurring greenhouse gases.

Bhopal Gas Tragedy

• The gas leaked in the Bhopal tragedy was methyl isocyanate.

Ozone Layer Location

• The ozone layer is found in the stratosphere.

Taj Mahal Threat

• Air pollution poses a threat to the beauty of the Taj Mahal due to its impact on the marble structure.

Air Pollutant

• Carbon dioxide is not typically considered a major air pollutant.

Aerosols

• Soot is an example of solid particle aerosols produced by combustion.

Incomplete Combustion Product

• Carbon monoxide is primarily produced due to incomplete burning of wood.

Pollution Causes

• Industrial activities, vehicular emissions, and agricultural practices contribute to pollution.

CNG

• CNG stands for compressed natural gas, a cleaner fuel alternative.

Water Pollution Effects

• Water pollution can lead to health issues, ecosystem damage, and water scarcity.

Chlorofluorocarbon Use

• Chlorofluorocarbons (CFCs) were used in refrigerants, aerosols, and foam-blowing agents.

Aquatic Life Requirement

• Oxygen is a vital requirement for aquatic life.

Wastewater Sources

• Wastewater released from industrial facilities and sewage treatment plants can be sources of bacteria.
