Between 0 and 4 percent of the Earth's atmosphere is made up of water vapor. The amount of water vapor present in the atmosphere, also known as humidity, is the most variable characteristic of the atmosphere and is largely dependent on air temperature.Know More
At 86 degrees Fahrenheit, a volume of air can hold up to 4 percent water vapor. At minus 40 F, air can hold no more than 0.2 percent water vapor.
Water vapor enters the atmosphere by way of evaporation from the Earth's surface. When a volume of air holds the maximum amount of water vapor possible for a given temperature, it is said to be saturated and has a relative humidity of 100 percent.Learn more about Atmosphere
Ozone is formed naturally when oxygen in the Earth's atmosphere is exposed to strong concentrations of ultraviolet light. It also forms artificially when nitrogen and oxygen emissions from internal combustion engines are exposed to sunlight.Full Answer >
Since the exosphere is the topmost layer of Earth's atmosphere, the air in it is very thin as it slowly fades into outer space. The air in the exosphere has multiple similarities to the vacuum of space, and it is generally characterized by the existence of light atmospheric gases like helium and hydrogen alongside trace amounts of atomic oxygen and carbon dioxide.Full Answer >
According to USA Today, the coldest time of the day comes just before sunrise because the earth has had all night to expel the heat from the previous day into the atmosphere. As soon as the sun begins to rise, the earth will immediately begin to heat up once again.Full Answer >
In meteorology, temperature inversions occur in the layer of the atmosphere closest to the Earth's surface, known as the troposphere. Temperature inversions in the atmosphere occur when a cool layer of air close to the Earth's surface is covered by a warm layer above.Full Answer >
