The temperature at the upper limit of the mesosphere, known as the mesopause, typically reaches around -90 degrees Celsius (-130 degrees Fahrenheit). This layer is situated approximately 85 to 100 kilometers (53 to 62 miles) above Earth's surface. The temperature decreases with altitude in the mesosphere, making it the coldest part of the Earth's atmosphere.
A flat gray layer of heavy clouds not far above the ground is typically referred to as a "stratus cloud." These clouds are characterized by their uniform, low-lying appearance and often bring overcast skies and light precipitation, such as drizzle or mist. Stratus clouds can create a gloomy atmosphere and limit visibility, particularly in foggy conditions.
The "effective volume" of the Earth's atmosphere is about 4.2 billion cubic kilometers. This figure is the surface area of the Earth (509 million square kilometers) times the "effective thickness" of the atmosphere (8.2 kilometers, or about 27,000 ft). The effective thickness and volume are what the thickness and volume of the atmosphere would be if the entire atmosphere were at sea level conditions. The actual volume of the atmosphere is considerably greater than its effective volume, as its pressure and density drop with increasing altitude. If we adopt the "Karman Limit" of 100 km elevation as the boundary between earth and space, the volume of the atmosphere would be 100 times 509 million or about 51 billion cubic kilometers. However, the Karman Limit is a non-physical and rather arbitrary boundary.
A common misconception about Earth's atmosphere is that it is unlimited and can constantly absorb greenhouse gases without consequence. In reality, there is a limit to how much greenhouse gases can be absorbed, leading to global warming and climate change.
all planets have atmospheres. However, Mercury has extremely low atmospheric pressure, Mars has an atmosphere way below the Armstrong Limit, and Venus and the Outer worlds have way too high of an atmosphere.

Troposhphere
The uppermost part of the Thermosphere, better known as the Exosphere.
The exosphere is the outermost layer of Earth's atmosphere that transitions into outer space. It does not have a defined upper limit and contains a very thin density of gas molecules that can reach thousands of kilometers above the planet's surface.
The different layers of atmosphere, starting with the lowest layer in which most clouds appear, is the troposphere. The next layer is the stratosphere, which has the ozone layer at its upper limit about 50 km above sea level. The next layer is called the mesosphere, and above this is the ionosphere which extends to about 1,000 km. Next is the thermosphere and then the outside layer of atmosphere called the exosphere, which reaches a height of about 6,000 km above sea level..
The atmosphere layer that is thinnest in size is the upper layer, the exosphere. 1. The troposphere is the first layer above the surface and contains half of the Earth's atmosphere. Weather occurs in this layer. 2. Many jet aircrafts fly in the stratosphere because it is very stable. Also, the ozone layer absorbs harmful rays from the Sun. 3. Meteors or rock fragments burn up in the mesosphere. 4. The thermosphere is a layer with auroras. It is also where the space shuttle orbits. 5. The atmosphere merges into space in the extremely thin exosphere. This is the upper limit of our atmosphere.
Exosphere is the layer of Earth's atmosphere with no definite outer limit. It extends from the top of the thermosphere to outer space and gradually transitions into the vacuum of space. The exosphere is where particles are so sparse that they can travel long distances without colliding with each other.
