1.
The greenhouse effect occurs because gases in the atmosphere trap energy from the sun. Which of the following gases are a part of this process?
Correct Answer
E. All of the Above
Explanation
The greenhouse effect occurs when certain gases in the atmosphere, including carbon dioxide, methane, nitrous oxide, and water vapor, trap energy from the sun. These gases act like a blanket, allowing sunlight to enter the Earth's atmosphere but preventing some of the heat from escaping back into space. This process leads to an increase in the Earth's temperature, known as global warming. Therefore, all of the gases mentioned are part of the greenhouse effect.
2.
When the greenhouse effect becomes stronger as increasingly more heat is being trapped on the Earth and consequently causing temperatures across the planet to rise it is called. . .
Correct Answer
E. Both A and C
Explanation
When the greenhouse effect becomes stronger and more heat is trapped on Earth, causing temperatures to rise, it is known as global warming. Climate change refers to the long-term changes in weather patterns and other environmental conditions that result from global warming. Both terms, global warming and climate change, are used to describe the phenomenon of increasing temperatures and its impact on the planet.

The Intergovernmental Panel on Climate Change (made up of the world's top scientists and climatologists) met for the first time in 1988 to discuss the threat of climate change and find the cause. In 2001 they came to a conclusion, what did they decide?
Correct Answer
C. Human activity is the primary cause for climate change
Explanation
The Intergovernmental Panel on Climate Change (IPCC) concluded that human activity is the primary cause for climate change. This means that the actions and behaviors of humans, such as burning fossil fuels and deforestation, are the main factors contributing to the changes in the Earth's climate. The IPCC, consisting of top scientists and climatologists, reached this conclusion after extensive research and analysis of the available evidence. This finding highlights the importance of addressing and reducing human activities that contribute to climate change in order to mitigate its impacts.
4.
Climate change has which of the following effects on the weather?
Correct Answer
E. All of the above
Explanation
Climate change has multiple effects on the weather. It leads to extreme heat waves, causing abnormally high temperatures for prolonged periods. Melting ice caps are another consequence of climate change, resulting in rising sea levels and changes in ocean currents. Climate change also leads to stronger and more frequent storms, including hurricanes and cyclones, due to increased energy and moisture in the atmosphere. Additionally, it can cause droughts, as changing weather patterns disrupt rainfall patterns and increase evaporation rates. Therefore, all of the options mentioned - extreme heat waves, melting ice caps, stronger more frequent storms, and drought - are effects of climate change on the weather.
5.
Climate change has killed % of coral reefs in the Western Indian Ocean?
Correct Answer
E. 92%
Explanation
The correct answer is 92%. This indicates that climate change has had a devastating impact on coral reefs in the Western Indian Ocean, with 92% of them being killed. This highlights the urgent need for action to address climate change and protect these fragile ecosystems.
6.
What happens when Carbon Dioxide dissolves in ocean water?
Correct Answer
A. It becomes Carbonic Acid - Acidifying the ocean
Explanation
When carbon dioxide dissolves in ocean water, it combines with water molecules to form carbonic acid. This process is known as ocean acidification. The increased levels of carbonic acid in the ocean lead to a decrease in the pH of the water, making it more acidic. This can have detrimental effects on marine life, such as the inability of shell-forming organisms to build their shells properly. Therefore, the correct answer is that carbon dioxide dissolving in ocean water leads to the formation of carbonic acid, which acidifies the ocean.
7.
Trees Carbon Dioxide.
Correct Answer
A. Store
Explanation
Trees store carbon dioxide through the process of photosynthesis. During photosynthesis, trees take in carbon dioxide from the atmosphere and convert it into glucose, which is then used for energy and growth. This process helps to remove carbon dioxide from the air, reducing its concentration and mitigating the effects of climate change. Therefore, the correct answer is "Store".
8.
As concluded by the IPCC, human activity has caused the Earth's temperature to rise an average of how many degrees?
Correct Answer
D. 1.35 degrees Fahrenheit
Explanation
According to the IPCC, human activity has caused the Earth's temperature to rise by an average of 1.35 degrees Fahrenheit. The IPCC is a scientific body that assesses the latest research on climate change, and their conclusion is based on extensive scientific evidence and studies. This increase in temperature is primarily due to the emission of greenhouse gases from human activities such as burning fossil fuels and deforestation. The IPCC's findings highlight the significant impact of human activity on global warming and emphasize the urgent need for mitigation and adaptation measures to address climate change.
9.
Which country refused to sign the Kyoto Protocol?
Correct Answer
C. United States of America
Explanation
The United States of America refused to sign the Kyoto Protocol. The Kyoto Protocol is an international agreement aimed at reducing greenhouse gas emissions and combating climate change. The United States argued that the protocol would harm their economy and that developing countries like China and India should also have binding emissions targets. As a result, the United States did not ratify the agreement, which limited its effectiveness and global impact.
10.
The United States has 4% of the world's population and emits % of the world's greenhouse gasses.
Correct Answer
A. 24%
Explanation
The United States has a relatively small population compared to the rest of the world, accounting for only 4% of the global population. However, it is a major contributor to greenhouse gas emissions, responsible for 24% of the world's total emissions. This can be attributed to various factors such as a high level of industrialization, a large transportation sector, and a high per capita energy consumption.
11.
Oil is a resource.
Correct Answer
C. Finite
Explanation
The correct answer is "Finite." Oil is a finite resource because it is formed over millions of years from the remains of ancient plants and animals. It takes a long time for new oil to be created, and the rate at which we are consuming oil is much faster than the rate at which it is being replenished. Therefore, oil is limited in quantity and will eventually run out if not managed properly.
12.
What is the single fastest-growing cause of climate change today?
Correct Answer
C. Air Travel
Explanation
Air travel is the single fastest-growing cause of climate change today. This is because airplanes emit large amounts of greenhouse gases, particularly carbon dioxide, into the atmosphere. These emissions contribute to the greenhouse effect, trapping heat and causing global temperatures to rise. The high altitude at which airplanes operate also enhances their climate impact, as the emissions released at this level have a more potent warming effect. As air travel continues to increase due to factors like globalization and tourism, its contribution to climate change becomes more significant.
