What happens to shortwave radiation from the Sun and longwave radiation from the Earth in the Earth's atmosphere?
What happens to shortwave radiation from the Sun and longwave radiation from the Earth in the Earth's atmosphere?
- Both shortwave and longwave radiations are absorbed by the Earth's surface
- Shortwave radiation is absorbed and re-radiated by greenhouse gases in the atmosphere, while longwave radiation is mostly reflected back into space
- Shortwave radiation is mostly absorbed by the Earth's surface, while longwave radiation is absorbed and re-radiated by greenhouse gases in the atmosphere (correct)
- Shortwave radiation is absorbed by greenhouse gases, while longwave radiation is reflected by the Earth's surface
How does albedo affect the temperature of a surface?
How does albedo affect the temperature of a surface?
- Albedo has no effect on surface temperature
- High albedo surfaces absorb more solar radiation and tend to be cooler, whereas low albedo surfaces reflect more solar radiation and tend to be warmer
- Both high and low albedo surfaces absorb equal amounts of solar radiation
- High albedo surfaces reflect more solar radiation and tend to be cooler, whereas low albedo surfaces absorb more solar radiation and tend to be warmer (correct)
Why is understanding planetary temperatures crucial for studying climate variations?
Why is understanding planetary temperatures crucial for studying climate variations?
- Because it allows prediction of short-term weather patterns
- Because it helps determine the greenhouse gas concentrations in the atmosphere
- Because it helps identify which planets have similar climates to Earth
- Because it provides insights into the factors influencing climate and temperature changes (correct)
