bec. of the gravity of the earth
The troposphere is the layer of Earth's atmosphere where practically all clouds and storms occur. This layer is closest to the Earth's surface and is characterized by decreasing temperature and pressure with increasing altitude.
The air temperature in the mesosphere layer decreases with increasing altitude. This is because the mesosphere is the coldest layer of the Earth's atmosphere, with temperatures decreasing to as low as -90 degrees Celsius at the top of the layer. The decrease in temperature is primarily caused by the decreasing density of gas molecules at higher altitudes in the mesosphere.
thermosphere
From Wikipedia:Temperature decreases with height in the mesosphere. The mesopause, the temperature minimum that marks the top of the mesosphere, is the coldest place on Earth and has an average temperature around −100 °C (−148.0 °F; 173.1 K)the mesosphere is the coldest layer in the atmosphere. It contains the ozone.OK!! the answer above is incorrect the coldest layer in the atmosphere is the Mesopause its the thin layer between the Mesosphere and Thermosphere. Also the Ozone is in the Stratosphere.Actually its correct because the mesopause is a part of the mesosphere....ok the 1st and 3rd answers are wrong! i should know im learning this in my 7TH GRADE SCIENCE CLASS! the ozone is in the stratosphere, the second closest layer to the earth. STUPIDS!
The thermosphere is the layer of the atmosphere that lies between the mesosphere and the exosphere. It is characterized by increasing temperatures with altitude and is where the auroras occur.
An increase in temperature with height in an atmospheric layer is called an inversion layer. This phenomenon is opposite to the normal decrease in temperature with increasing altitude in the Earth's atmosphere.
The lowest layer of Earth's atmosphere is called the troposphere. This layer is where weather events occur and temperature decreases with increasing altitude.
The layer of the atmosphere that contains weather is the troposphere. It is the lowest layer of the atmosphere where temperature decreases with increasing altitude and where most weather phenomena occur, including clouds, precipitation, and wind.
The troposphere is the layer of Earth's atmosphere where practically all clouds and storms occur. This layer is closest to the Earth's surface and is characterized by decreasing temperature and pressure with increasing altitude.
The thermosphere is the layer of the atmosphere that has the greatest range in temperature, with temperatures increasing with altitude due to the absorption of solar radiation. Temperature in the thermosphere can vary from below -100°C at the bottom to over 2,500°C at higher altitudes.
The Mesosphere has the lowest temperature of the layers of Earth's atmosphere because Temperature decreases with height in the mesosphere. The mesopause, the temperature minimum that marks the top of the mesosphere, is the coldest place on Earth and has an average temperature around −100 °C (−148.0 °F; 173.1 K)
In the troposphere (the layer of the earth that we live in), the temperature decreases with increasing height. The troposphere contains approximately 80% of the atmosphere's mass and 99% of its water vapour and aerosols.As you increase height, you reach areas of the atmosphere that have fewer and fewer air molecules (which means the air is less dense) because gravity is keeping the majority of air molecules closer to the ground. So, at higher altitudes, the air is less able to store heat.
The layer in which temperatures increase with elevation is the troposphere. This is the layer above the surface of the Earth. The troposphere contains half of the Earth's atmosphere. Weather occurs in this layer.
A layer in the atmosphere in which temperature increases with altitude.
The air temperature in the mesosphere layer decreases with increasing altitude. This is because the mesosphere is the coldest layer of the Earth's atmosphere, with temperatures decreasing to as low as -90 degrees Celsius at the top of the layer. The decrease in temperature is primarily caused by the decreasing density of gas molecules at higher altitudes in the mesosphere.
Assuming the depth of the layer is restricted to between 1000mb and 500mb, and increasing with time, it is almost certain that the surface temperature will remain constant, thus not increasing or descreasing.
The layer of the atmosphere with the lowest temperature is the mesosphere. Temperatures in this layer can drop as low as -90 degrees Celsius (-130 degrees Fahrenheit).
