What part of the atmosphere is at 10 km?
Troposphere
Troposphere. The troposphere is the lowest layer of our atmosphere. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level.
What percentage of the atmosphere is below 5.5 km?
A mixture of the heavier gases in the atmosphere lies near the earth. About 95% of the atmosphere by mass below the 25 km altitude. For the Earth, half the mass of the atmosphere lies below about 5.5 km altitude, and 99 per cent below 30 km.
How many km is each layer of the atmosphere?
Thermosphere: 80 to 700 km (50 to 440 miles) Mesosphere: 50 to 80 km (31 to 50 miles) Stratosphere: 12 to 50 km (7 to 31 miles) Troposphere: 0 to 12 km (0 to 7 miles)
What is the temperature of the atmosphere at 5 km?
Temperatures in the troposphere drop an average of 6.5 degrees C per kilometer (3.5 degrees F per 1,000 feet) of altitude. Five kilometers up, the temperature would be 15 – (5 x 6.5) = -17.5 degrees C. This rough equation remains reasonably accurate up to the tropopause.
How many km does ionosphere extend into the atmosphere?
The region of the atmosphere above about 80 km is also caused the “ionosphere”, since the energetic solar radiation knocks electrons off molecules and atoms, turning them into “ions” with a positive charge.
What is the height of the mesosphere?
about 50 to 85 km
The mesosphere is a layer of Earth’s atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. Temperature decreases with height throughout the mesosphere.
What are the pauses in the atmosphere?
Those pauses are the dividing lines between the troposphere, the stratosphere, the mesosphere, and the thermosphere. The pause regions are even named as well – the tropopause, the stratopause, and the mesopause. The following plot/figure shows these layers on top of the temperature plot from above.
What is normal atmospheric temperature?
NIST uses a temperature of 20 °C (293.15 K, 68 °F) and an absolute pressure of 1 atm (14.696 psi, 101.325 kPa). This standard is also called normal temperature and pressure (abbreviated as NTP).
How far does the atmosphere extend?
Earth’s atmosphere stretches from the surface of the planet up to as far as 10,000 kilometers (6,214 miles) above. After that, the atmosphere blends into space.
