What are the main factors that affect density altitude?
There are three important factors that contribute to high density altitude:
- Altitude. The higher the altitude, the less dense the air.
- Temperature. The warmer the air, the less dense it is.
- Humidity.
- 80 oF.
- 90 oF.
- 100 oF.
- 110 oF.
- 120 oF.
How does the temperature change as altitude increases?
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases.
Why does water vapor not contribute to global warming?
On average, it probably accounts for about 60% of the warming effect. However, water vapor does not control the Earth’s temperature, but is instead controlled by the temperature. This is because the temperature of the surrounding atmosphere limits the maximum amount of water vapor the atmosphere can contain.
How is water important for Earth’s climate?
Water vapor is also the most important greenhouse gas in the atmosphere. Heat radiated from Earth’s surface is absorbed by water vapor molecules in the lower atmosphere. The water vapor molecules, in turn, radiate heat in all directions. Some of the heat returns to the Earth’s surface.
Where does most water vapor come from?
About 90 percent of water in the atmosphere is produced by evaporation from water bodies, while the other 10 percent comes from transpiration from plants.
What is the effect of carbon monoxide on human health?
Carbon monoxide symptoms mimic the flu: headaches, fatigue, nausea, dizziness, confusion, and irritability. Continued exposure can lead to vomiting, loss of consciousness, brain damage, heart irregularity, breathing difficulties, muscle weakness, abortions and even death.
What are the harmful effects of carbon monoxide on human beings Plants & Animals?
Chronic poisoning Chronic exposure to relatively low levels of carbon monoxide may cause persistent headaches, lightheadedness, depression, confusion, memory loss, nausea, hearing disorders and vomiting. It is unknown whether low-level chronic exposure may cause permanent neurological damage.
