Why does air stop rising at the top of the convection?
As the air rises in a convection cell, it eventually reaches the top of the troposphere, known as the tropopause. At the tropopause, the temperature stops decreasing with altitude, which inhibits further rising of the air. Additionally, the density of the air decreases with altitude, causing it to become less buoyant and preventing further upward movement.
Is the troposphere equal in depth everywhere and why or why not?
Definitely not - it varies with temperature. The top of the troposphere is defined by (to simplify) the point where the temperature stops decreasing with height. This is going to vary depending on the temperature of the air below. The troposphere can be less than half the height at the poles as it is at the equator because cold air takes up much less space. Additionally, its height varies in the same location as the seasons change, or even as different air masses move through.
What is the lowest temperature in the trophosphere?
The troposphere, the lowest layer of Earth's atmosphere, is heated from below. The troposphere is warmest at the bottom near Earth's surface. The troposphere is coldest at its top, where it meets up with the layer above (the stratosphere) at a boundary region called the tropopause. Temperatures drop as you move upward through the troposphere.Sunlight streams down from space through the atmosphere, striking the ground or ocean beneath. The sunlight heats the surface, and that surface radiates the heat into the adjacent atmosphere. Atmospheric scientists use a concept called a "standard atmosphere" to represent an average atmosphere with variations caused by weather, latitude, season, and so forth, removed. In the standard atmosphere model, the temperature at sea level at the bottom of the troposphere is 15° C (59° F). Higher up in the troposphere, where less heat from the surface warms the air, the temperature drops. Typically, the temperature drops about 6.5° C with each increase in altitude of 1 kilometer (about 3.6° F per 1,000 feet). The rate at which the temperature changes with altitude is called the "lapse rate". In the standard atmosphere, by the time you reach the top of the troposphere the temperature has fallen to a chilly -57° C (-70° F).Of course, the atmosphere is always changing and is never "standard". Temperatures in the troposphere, both at the surface and at various altitudes, do vary based on latitude, season, time of day or night, regional weather conditions, and so on. In some circumstances, the temperature at the top of the troposphere can be as low as -80° C (-110° F). When a weather phenomenon called at "temperature inversion" occurs, temperature in some part of the troposphere gets warmer with increasing altitude, contrary to the normal situation.In the layer above the troposphere, the stratosphere, temperature rises with increasing altitude. In the stratosphere, the air is heated from above by ultraviolet "light" which is absorbed by ozone molecules in the air. The tropopause is the boundary between the troposphere (below) and the stratosphere (above). The tropopause occurs where the temperature stops dropping with increasing altitude (in the troposphere) and begins climbing with increasing altitude (the stratosphere).
What keeps clouds rain and snow restricted to the troposphere?
The higher you get in the troposphere, the colder it gets. However, when you reach the stratosphere the temperature starts to increase. A warm parcel of air rising creates a cumulus cloud, and eventually turns into a cumulonimbus cloud, which is a rain/snow cloud. As the warm updraft relies on colder surrounding air for it to be buoyant, as it gets warmer again it is no longer buoyant and begins to flatten out at the base of the stratosphere, unable to rise any further. Evidence of this is shown at the top of the cloud, which appears flattened like a pancake or appearing like an anvil. So it is this increase of temperature in the stratosphere which keeps rain and snow restricted to the troposphere.
Does the troposphere have less variable conditions than any other layers?
No, it has more variable conditions by most definitions. This is because it is unstable, with cold air at the top and warm air at the bottom. It also contains water vapor, which is vital to most forms of weather.
Which top portion of troposphere?
The top portion of the troposphere is known as the tropopause. It is characterized by a stable temperature gradient and acts as a boundary between the troposphere and the stratosphere above.
Does the temperature stay constant at the top of the troposphere?
yes

How does temperature change as increases in the troposphere?
As the altitude increases in the Troposphere, The air temperature decreases. When about 1 kilometer increases in altitude, the air cools about 6.5 degrees Celsius. And at the very top of the Troposphere the air temperature stays the same at around -60 degrees Celsius.
How does temperature change as height increases the troposphere?
As the altitude increases in the Troposphere, The air temperature decreases. When about 1 kilometer increases in altitude, the air cools about 6.5 degrees Celsius. And at the very top of the Troposphere the air temperature stays the same at around -60 degrees Celsius.
How does temperature change as the height increases in troposphere?
As the altitude increases in the Troposphere, The air temperature decreases. When about 1 kilometer increases in altitude, the air cools about 6.5 degrees Celsius. And at the very top of the Troposphere the air temperature stays the same at around -60 degrees Celsius.
What condition that occurs in the troposphere when warm air sits on top of cold air?
Temperature inversion occurs in the troposphere when warm air sits on top of cold air, causing the normal temperature profile to invert. This can lead to pollutants being trapped near the surface, affecting air quality. Temperature inversions are more common during calm, clear nights.

What is the temperature in Celsius of the temposphere?
The temperature in the troposphere, which is the lowest layer of Earth's atmosphere, typically decreases with altitude, averaging around 15°C at sea level. As you ascend, the temperature can drop to about -50°C at the top of the troposphere, which varies based on geographical location and weather conditions. This layer extends from the surface up to about 8 to 15 kilometers high, depending on the region.
What layer in the atmosphere is the top portion of the troposphere?
The troposphere is the portion of the atmosphere closest to earth. It is below the stratosphere.
