The answer depends on whether you want the mass of the atmosphere, the depth (height) or the volume above 8.5 km.
The layer extending 50-85km above Earth is the mesosphere. This layer is characterized by a decrease in temperature with increasing altitude and is where most meteorites burn up upon entering the Earth's atmosphere.
The answer is 85km
1. Troposphere (8-18km above Earth's surface) 2.Stratosphere (50km above Earth's Surface) 3. Mesosphere (50-85km) 4.Thermosphere (85-450km) 5.Exosphere (450-10,000km)
85km is 52.8166 miles.
The thermosphere, which is located above the mesosphere, contains only a tiny fraction of the atmosphere's mass. Despite its low density, it can reach very high temperatures due to the absorption of solar radiation.
85km
The approximate mole fraction of nitrogen in the atmosphere is about 0.7808, and the approximate mole fraction of oxygen is about 0.2095. When combined, the mole fraction of nitrogen and oxygen in the atmosphere is approximately 0.9903.
A = 22,698 km2
80km/h to 85km/h.
The five different layers of Earth's atmosphere are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. These layers vary in temperature, composition, and altitude, with the troposphere being the lowest layer where most weather occurs and the exosphere being the outermost layer where the atmosphere gradually transitions into space.
It is above the atmosphere and not in any atmosphere.
It is not necessarily cold above the atmosphere. In direct sunlight, it can be quite hot.
