The atmosphere is divided into layers based on how the temperature in that layer changes with altitude, the layer’s temperature gradient. The temperature gradient of each layer is different. In some layers, temperature increases with altitude and in others it decreases.
Why is the Earth's atmosphere warmer at the surface?
The reason it is warmer at the surface is simple. The air is warmed by heat given off by the Earth! The farther away from the surface the air moves, the less heat there is to absorb. From 10 to 20 kilometers the atmosphere is stable.
What is the relationship between heat and temperature in the atmosphere?
Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere. This increase in temperature with height means warmer air is located above cooler air.
What is the true temperature profile of the atmosphere?
The true temperature profile of the atmosphere is shown in the image. The air at the surface up to around 10 kilometers is called the troposphere. The reason it is warmer at the surface is simple. The air is warmed by heat given off by the Earth! The farther away from the surface the air moves, the less heat there is to absorb.
Did you know that the atmosphere actually warms up again?
And even less know that the atmosphere actually warms up again! The true temperature profile of the atmosphere is shown in the image. The air at the surface up to around 10 kilometers is called the troposphere. The reason it is warmer at the surface is simple. The air is warmed by heat given off by the Earth!
What's a temperature profile?
A temperature profile is a graph that shows changes in temperature at different locations in the atmosphere. The temperature profile graph displays...
What is the maximum atmospheric temperature?
The atmospheric temperature is a range of temperatures that occur in the different layers of the atmosphere. The temperature changes at different l...
What is atmosphere temperature profile?
The atmosphere temperature profile of Earth demonstrates the temperature as it changes in the atmosphere. It displays changes in temperature as the...
What are the temperatures of the atmosphere layers?
The temperature varies significantly from one layer to another and even within a layer of the atmosphere. The temperature ranges in the atmospheric...
What is the normal atmospheric temperature?
The temperature at different locations within the atmosphere varies greatly. The normal atmospheric temperature is the expected temperature at any...
What happens to the temperature of the troposphere as you climb higher?
As one climbs higher, the temperature drops from an average around 62°F (17°C) to -60°F (-51°C) at the tropopause. Average temperature profile for the lower layers ...
Which layer of the atmosphere is considered the middle atmosphere?
Both the stratosphere (next layer down) and the mesosphere are considered the middle atmosphere. The transition boundary which separates the mesosphere from the stratosphere is called the stratopause.
What causes the temperature to increase in the thermosphere?
As such, incoming high energy ultraviolet and x-ray radiation from the sun begins to be absorbed by the molecules in this layer and causes a large temperature increase.
What is the outermost layer of the atmosphere?
Exosphere. This is the outermost layer of the atmosphere. It extends from the top of the thermosphere to 6,200 miles (10,000 km) above the earth. In this layer, atoms and molecules escape into space and satellites orbit the earth. At the bottom of the exosphere is the thermopause located around 375 miles (600 km) above the earth.
How far above Earth's surface is the oxygen layer?
This layer extends from around 31 miles (50 km) above the Earth's surface to 53 miles (85 km). The gases, including the oxygen molecules, continue to become denser as one descends. As such, temperatures increase as one descends rising to about 5°F (-15°C) near the bottom of this layer.
What does it mean when the temperature increases with height?
This increase in temperature with height means warmer air is located above cooler air. This prevents "convection" as there is no upward vertical movement of the gases. As such the location of the bottom of this layer is readily seen by the 'anvil-shaped' tops of cumulonimbus clouds.
What is the lower atmosphere?
Known as the lower atmosphere almost all weather occurs in this region. The troposphere begins at the Earth's surface and extends from 4 to 12 miles (6 to 20 km) high.
Answer
Different temperature gradients create different layers within the atmosphere. ... The troposphere is heated from the ground, so temperature decreases with altitude. Because warm air rises and cool air sinks, the troposphere is unstable. In the stratosphere, temperature increases with altitude.

Why is the atmosphere warmer?
The reason it is warmer at the surface is simple. The air is warmed by heat given off by the Earth! The farther away from the surface the air moves, the less heat there is to absorb.
What is the atmosphere called when it warms up with height?
From 10 to 20 kilometers the atmosphere is stable. This region is called the tropopause. From 20 to about 50 kilometers is the stratosphere. In this region the air actually warms with height! Ozone is concentrated in this part of the atmosphere and it absorbs ultraviolet light from the Sun. More light is absorbed at higher altitudes compared to ...
Why does the temperature decrease with height?
In the mesosphere, the temperature decreases with height again, because there is very little ozone to warm up the air. Finally, the mesopause divides the mesosphere from the thermosphere, which is the section of the atmosphere higher than 90 km. In this region, the temperature increases again!
What happens to the temperature at 50 km?
More light is absorbed at higher altitudes compared to the lower stratosphere, so the temperature increases. But at 50 kilometers, the temperature levels out again in a region called the stratopause. At about 55 km, the mesosphere begins. In the mesosphere, the temperature decreases with height again, because there is very little ozone ...
Is it colder on top of a mountain?
Most people know that it is colder on top of a mountain compared to the ground, but few actually know why. And even less know that the atmosphere actually warms up again! The true temperature profile of the atmosphere is shown in the image. The air at the surface up to around 10 kilometers is called the troposphere.
