Question The main greenhouse gas is _______. (1 point) Responses carbon dioxide carbon dioxide nitrous oxide nitrous oxide oxygen oxygen methane
carbon dioxide
The main greenhouse gas is carbon dioxide.
The main greenhouse gas is carbon dioxide.
To arrive at this answer, we can start by understanding what greenhouse gases are. Greenhouse gases are gases in the Earth's atmosphere that trap heat from the sun, thereby contributing to the greenhouse effect and ultimately leading to global warming.
Now, to determine the main greenhouse gas, we need to consider the gases that are most abundant and have the greatest impact on the greenhouse effect. Although there are several greenhouse gases, including nitrous oxide, oxygen, and methane, carbon dioxide is considered to be the most significant and abundant greenhouse gas.
To verify this information, you can consult reputable sources such as scientific journals, environmental organizations, or government agencies that focus on climate change and atmospheric conditions. These sources can provide more detailed and up-to-date information on the topic.

Survivors of the tsunami recognized that a receding ocean was a sign of danger.
During the Indian Ocean tsunami of 2004, one of the common observations made by survivors was the sudden and significant retreat of the ocean water, exposing a large portion of the shoreline. This phenomenon is known as a "receding ocean" or "drawback." In many cases, people who were unaware of the impending tsunami were drawn to the exposed seabed, curious about the unusual sight. However, the receding ocean is actually a warning sign of an imminent tsunami, indicating that the ocean is rapidly pulling back before a massive wave comes crashing ashore.
