Question 1

A key value of ozone in the stratosphere is its ability to interact with and prevent ___ from reaching the Earth's inhabitants.

Accepted Answer

Ozone in the stratosphere plays a crucial role in absorbing and preventing most of the sun's harmful ultraviolet (UV) radiation from reaching the Earth's surface, thus protecting living organisms from its damaging effects.

Question 2

An environmental issue of global importance is ozone depletion of the

Accepted Answer

Ozone depletion primarily occurs in the stratosphere, where the ozone layer is located. This layer absorbs the majority of the sun's harmful ultraviolet radiation, and its depletion has significant environmental impacts.

Question 3

An increase of 2 deg C in the Earth's average temperature by the year 2100

Accepted Answer

An increase of 2 degrees Celsius in Earth's average temperature would lead to significant environmental and climatic changes, affecting ecosystems, weather patterns, sea levels, and global climate systems unevenly across different regions of the planet.

Question 4

A single chlorine atom such as a product of the breakdown of CFCs, can destroy ___ ozone molecules in the stratosphere.

Accepted Answer

A single chlorine atom can destroy up to 100,000 ozone molecules in the stratosphere. This is because the chlorine acts as a catalyst in the breakdown of ozone molecules, meaning it is not consumed in the reaction and can continue to destroy ozone molecules repeatedly.

Question 5

Atmospheric gases that produce air quality problems on a global rather than on a local scale have residence times that are measured in

Accepted Answer

Atmospheric gases that cause global air quality problems, such as carbon dioxide and methane, have long residence times in the atmosphere, often measured in years. This long duration allows them to disperse widely and affect global climate and air quality.

Question 6

Atmospheric gases that produce air quality problems on a global scale are generally considered locally, to be

Accepted Answer

The answer of Atmospheric gases that produce air quality problems...

Question 7

Chlorinated fluorinated hydrocarbons (CFCs) are

Accepted Answer

CFCs are stable in the lower atmosphere but become harmful in the stratosphere where they break down ozone molecules, leading to ozone layer depletion.

Question 8

Climate change, or global warming, would not affect the polar ice caps, glaciers, or sea levels

Accepted Answer

Climate change, or global warming, leads to the melting of polar ice caps and glaciers, contributing to rising sea levels.

Question 9

Compared to carbon dioxide (CO₂), the greenhouse gas methane (CH₄) is

Accepted Answer

Methane (CH4) is more effective at trapping heat in the atmosphere than carbon dioxide (CO2), making it a more potent greenhouse gas per molecule. However, CO2 is more abundant in the Earth's atmosphere, making methane less concentrated compared to CO2.

Question 10

In 1990, representatives of 93 countries signed the London Agreement to phase out all __- by the year 2000.

Accepted Answer

The London Agreement, an amendment to the Montreal Protocol, aimed to phase out the production of chlorofluorocarbons (CFCs) by the year 2000 due to their harmful effects on the ozone layer.

Question 11

Islands such as some in the Pacific Ocean could be wiped out by a significant rise in sea level.

Accepted Answer

Many islands in the Pacific Ocean are low-lying and would be significantly impacted or even submerged by a rise in sea levels, which is a consequence of climate change and melting polar ice caps.

Question 12

Over time, since 1880,

Accepted Answer

Since 1880, both global temperatures and carbon dioxide concentrations have shown a significant increase, largely attributed to human activities such as the burning of fossil fuels and deforestation. This trend is well-documented and widely accepted in the scientific community.

Question 13

State two ways to decrease our planet's carbon dioxide production.

Accepted Answer

Reducing energy consumption and finding alternative energy sources, such as solar or wind, can decrease carbon dioxide production.

Question 14

The ability of the Earth to trap the sun's heat (allowing it to enter but not to exit) is known as the

Accepted Answer

The Greenhouse Effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere. This effect is responsible for the Earth's ability to trap the sun's heat, allowing it to enter but not easily exit, thus maintaining the planet's warm temperature.

Question 15

Chlorinated fluorinated hydrocarbons (CFCs) are

Accepted Answer

Chlorinated fluorinated hydrocarbons (CFCs) are known to be powerful greenhouse gases. They have a high global warming potential, contributing significantly to the greenhouse effect and the warming of the Earth's atmosphere.

Question 16

The greenhouse gas nitrous oxide (N₂O)

Accepted Answer

Nitrous oxide (N2O) is commonly known as "laughing gas" due to its euphoric effects when inhaled.

Question 17

The inability of humans to accurately predict the results of all of their actions is known as the Law of

Accepted Answer

The Law of Unintended Consequences highlights the complexity of systems and human actions within them, acknowledging that actions often have effects that are unforeseen or unintended.

Question 18

The Intergovernmental Panel on Climate Change (IPCC) predicts that by the year 2100, the Earth's climate will be

Accepted Answer

The Intergovernmental Panel on Climate Change (IPCC) has consistently predicted that the Earth's climate will become significantly warmer by the year 2100 due to human activities that increase greenhouse gases in the atmosphere.

Question 19

The permanently frozen layer of the ground a short distance under the surface is called the

Accepted Answer

Permafrost refers to the ground, including rock or soil, that remains at or below the freezing point of water for two or more years. It is typically found in high latitude regions of the Earth, such as the Arctic and Antarctic, and at high elevations in mountains.

Question 20

To date, no international agreements to combat climate change have been made.

Accepted Answer

Several international agreements aimed at combating climate change have been established, including the Kyoto Protocol and the Paris Agreement.
