Question

Which factor should be included in a model of energy flow into the atmosphere?
places experiencing drought
variations in local temperatures
number of flood days per year
concentrations of greenhouse gases

Answer 1

In a model of energy flow into the atmosphere, the most relevant factor to include would be **concentrations of greenhouse gases**.

Greenhouse gases such as carbon dioxide, methane, and water vapor play a significant role in regulating the Earth's energy balance by trapping heat in the atmosphere. This affects radiative forcing and can significantly influence temperature and climate patterns.

While the other factors—drought conditions, local temperature variations, and flood days—can certainly impact weather and climate, they are more often results or consequences of energy flow and atmospheric conditions rather than direct contributors to the energy flow itself.
