What layer of the atmosphere contains all the water vapor?
The Troposphere
The Troposphere The actual change of temperature with height varies from day to day, depending on the weather. The troposphere contains about 75% of all of the air in the atmosphere, and almost all of the water vapour (which forms clouds and rain).
Which contains the most water air at?
The troposphere contains 99 % of the water vapor in the atmosphere. Water vapor concentrations vary with latitude. They are greatest above the tropics, where they may be as high as 3 %, and decrease toward the polar regions.
In which layer of the atmosphere does most condensation occur?
The cycle, which occurs in the troposphere, begins as the sun evaporates large amounts of water from the earth’s surface and the moisture is transported to other regions by the wind. As air rises, expands, and cools, water vapor condenses and clouds develop.
Which layer of the atmosphere did the Concorde cruise?
The Concorde aircraft cruised at Mach 2 at about 19,000 m (62,000 ft), and the SR-71 cruised at Mach 3 at 26,000 m (85,000 ft), all within the stratosphere.
Which atmospheric layer contains the ozone layer?
the stratosphere
The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth’s surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.
Where is the most water in the atmosphere?
Most water is in the troposphere, the lowest level of the atmosphere. This is the layer that contains most clouds, and almost all of our weather. Trace amounts of water vapor, often in the form of ice crystals, exists in the second layer, the stratosphere.
What makes up the atmosphere of the Earth?
We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions. Water vapor and dust are also part of Earth ’s atmosphere.
Where does water vapor occur in the troposphere?
The troposphere contains 99% of the water vapor in the atmosphere. Water vapor concentrations vary with latitudinal position(north to south). They are greatest above the tropics, where they might be as high as 3% and decrease toward the polar regions.
Which is the most dense layer of the atmosphere?
Between about 53 miles (85 km) and 375 miles (600 km) lies the thermosphere. This layer is known as the upper atmosphere. While still extremely thin, the gases of the thermosphere become increasingly more dense as one descends toward the earth.
