Trivia Quiz About Global Warming

Explanation
Carbon dioxide is the main greenhouse gas that can cause global warming. Greenhouse gases trap heat in the Earth's atmosphere, leading to an increase in the Earth's temperature. Carbon dioxide is released into the atmosphere through various human activities such as burning fossil fuels, deforestation, and industrial processes. It has a significant impact on climate change and is the primary driver of global warming. Oxygen and nitrogen are not greenhouse gases and do not contribute to global warming in the same way that carbon dioxide does.

Explanation
Human activity is the major cause of global warming because it involves the release of greenhouse gases, such as carbon dioxide, into the atmosphere. These gases trap heat from the sun, leading to an increase in the Earth's temperature. Activities such as burning fossil fuels for energy, deforestation, and industrial processes contribute significantly to the emission of these gases. The accumulation of greenhouse gases in the atmosphere over time has resulted in the phenomenon of global warming, causing climate change and its associated impacts on the environment and ecosystems.

Explanation
In 1750, carbon dioxide was at its lowest level. This is because it was before the Industrial Revolution, when human activities significantly increased the release of carbon dioxide into the atmosphere. During this time, the burning of fossil fuels and deforestation had not yet contributed to the significant rise in carbon dioxide levels that we see today. Therefore, 1750 marks a period when carbon dioxide concentrations were relatively low compared to subsequent years.

Explanation
Fossil fuels are used to heat homes and cars, and they contribute to global warming. When fossil fuels such as coal, oil, and natural gas are burned for heating or transportation purposes, they release greenhouse gases like carbon dioxide into the atmosphere. These greenhouse gases trap heat, leading to the greenhouse effect and global warming. Gold and silver are not used for heating purposes and do not contribute to global warming, making them incorrect options.

Explanation
Carbon dioxide is the main greenhouse gas because it is the most abundant and has the highest ability to trap heat in the Earth's atmosphere. It is released through natural processes like respiration and volcanic activity, but human activities such as burning fossil fuels and deforestation have significantly increased its concentration in the atmosphere. This leads to the greenhouse effect, where carbon dioxide and other greenhouse gases trap heat, causing global warming and climate change.
