Why do planes fly at high altitudes?
The reason aeroplanes fly so high is due to improved fuel efficiency. A jet engine operates more efficiently at higher altitude where the air is much thinner, allowing an aircraft to travel faster whilst at the same time, burning less fuel.
Which layer of the atmosphere do airplanes usually travel?
Stratosphere
Can planes fly in the mesosphere?
It extends from about 50 to 85 km (31 to 53 miles) above our planet. Temperature decreases with height throughout the mesosphere. Weather balloons and other aircraft cannot fly high enough to reach the mesosphere. Satellites orbit above the mesosphere and cannot directly measure traits of this layer.
What is the hottest layer?
thermosphere
What is above the troposphere?
the stratosphere
What are two characteristics of the upper troposphere?
The troposphere extends up to a height of about 18km at the equator and declines gradually to a height of 8km at the poles. The upper limit of the troposphere calls the tropopause. The temperature stops decreasing in it. It may be as low as -580C.
What is the thickness of troposphere?
The troposphere is the lowermost layer of the atmosphere. Its average height is 13 km and extends roughly to a height of 8 km near the poles and about 18 km at the equator. Thickness of the troposphere is greatest at the equator because heat is transported to great heights by strong convectional currents.
Where is the troposphere the thickest?
the equator
What is an example of troposphere?
The troposphere is the lowest layer of the atmosphere with water vapor, vertical winds and temperatures that decrease as the altitude increases. An example of the troposphere is the layer below the tropopause. At the top of this region, temperatures are close to −55°C (−67°F). …
What is the role of troposphere?
MEMPHIS, TN (WMC) -The troposphere is the lowest layer of Earth’s atmosphere and the site of all-weather on Earth. Water vapor it important as it will absorb solar energy and thermal radiation from the surface of Earth, thus regulating the air temperature.
What are 3 characteristics of the troposphere?
It contains three-quarters of the mass of the Earth’s atmosphere and is composed of 78% nitrogen, 21% oxygen, and a 1% mixture of argon, water vapor, and carbon dioxide. Air at the bottom of the troposphere or near the Earth’s surface is warmer, which means the higher the altitude, the colder it is.
How does the troposphere support life?
The troposphere is the only atmospheric layer that can support life. The higher layers have filtered out the harmful radiation, and there are large amounts of water vapor. This is the layer where clouds develop, birds fly, and pollution collects. Yes, the troposphere is where humans most pollute the atmosphere.
