The thermosphere is.
in the very very top
there are 5, troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
The Thermosphere contains the ionsphere and exosphere with nitrogen and other gases
thermosphere
The thermosphere is what we call the layer between the mesosphere and the exosphere. We associate that name with the region of the atmosphere between altitudes of 90 to 1,000 km (56 to 621 miles).
The altitude of the Thermosphere is from about 50 miles to 310 miles. The Thermosphere is the biggest of all layers of the Earth's atmosphere.
The thermosphere, which is a region of the Earth's atmosphere, is above the mesosphere. The thermosphere helps the planet because it absorbs most of the X-ray and UV radiation from the Sun. The thermosphere extends from 53 miles to about 621 miles above the Earth's surface.
The thermosphere is a layer of Earth's atmosphere above the mesosphere. The thermosphere extends from 50 to 55 miles (80-90 km) above sea level, with the upper limit undefined. The temperature in the thermosphere initially rises rapidly with heights up to about 120 miles (200 km) and thereafter increases more slowly. Above 120 miles (200 km) - depending on solar activity - the temperature varies between 600° and 2000°C (1100 and 3600°F).

The ionosphere begins at around 85 km and ends at around 600 km, making it start in the border of mesosphere/ thermosphere and end in the border of thermosphere/ exosphere.
The hottest layer is the mesosphere that is why meteors and asteroids burn in this layer .
Calgary has a width of about 22 miles from east to west and a length of about 19 miles from north to south, making the distance from one end to the other approximately 22 miles.
The four main layers of Earth's atmosphere are Toposphere, Stratosphere, Mesosphere, and Thermosphere. (The Thermosphere ends at 62 miles from earth's surface. or, where space starts.TroposphereExosphereIonosphereOzonosphere
