How Much Do You Know About Global Warming?

Explanation
The term "global" refers to something that is worldwide in scope or extent. It implies that it encompasses or relates to the entire world or a large portion of it. In this context, "global" means that it is not limited to a specific region or country, but rather includes people, events, or phenomena from all around the world.

Explanation
The statement "is the earth getting colder" is followed by the answer "False." This suggests that the Earth is not getting colder.

Explanation
Burning fossil fuels is the main cause of global warming. When fossil fuels such as coal, oil, and natural gas are burned for energy, they release greenhouse gases, primarily carbon dioxide, into the atmosphere. These greenhouse gases trap heat from the sun and prevent it from escaping back into space, leading to a rise in global temperatures. This phenomenon, known as the greenhouse effect, is responsible for the increase in global temperatures and the resulting climate change.

Explanation
Global warming can lead to an increase in drought conditions and the occurrence of violent and severe storms. These effects are caused by the rising temperatures and changes in weather patterns associated with global warming. Drought can result in water scarcity, crop failure, and the loss of natural habitats. Violent and severe storms, such as hurricanes and cyclones, are intensified by the warmer ocean temperatures and can cause widespread destruction and loss of life. These effects of global warming have significant impacts on ecosystems, economies, and human well-being.

Explanation
The correct answer is "co2 stands for carbon dioxide." CO2 is the chemical formula for carbon dioxide, which is a colorless gas that is a byproduct of combustion and respiration. It is a greenhouse gas that contributes to climate change and is also used in various industrial processes.
