How does convection occurs in the troposphere quizlet?
The uneven heating of the regions of the troposphere by the Sun causes convection currents and winds. Warm air from Earth's surface rises and cold air above it rushes in to replace it.
How does the air in the stratosphere differ from the troposphere quizlet?
nitrogen,oxygen, and water vapor. how does temperature change in the troposphere differ from the stratosphere? the temperature in the troposphere decreases while the temperature in the stratosphere increases because of the density of air molecules.

Why does Venus have such a large difference in temperature between its no atmosphere temperature and its actual temperature?
In the case of Venus, it has a runaway Greenhouse Effect. Its atmosphere is mainly carbon dioxide, a highly effective Greenhouse gas, and very thick so it heats the surface of Venus to a much higher temperature than it would have without an atmosphere.
How does convection occur in troposphere?
The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles )causes convection currents, large-scale patterns of winds that move heat and moisture around the globe.
How is heat moved through the troposphere?
Within the troposphere, heat is transferred mostly by convection. When the air near the ground is heated, the molecules have more energy and move faster. The molecules bump into one another and move farther apart, or become less dense. Cooler, denser air sinks, forcing the warmer, less dense air to rise.
How are the troposphere and the stratosphere different?
They differ in important ways as well. The troposphere has a negative temperature gradient, is constantly convecting, has abundant clouds and has abundant moisture. The stratosphere has a positive temperature gradient, has generally stable layers of air, has no clouds, except for at the poles, and is fairly dry.
What’s the difference between ozone in the stratosphere and ozone in the troposphere?
The key difference between stratospheric ozone and tropospheric ozone is that stratospheric ozone concentration is very high, whereas tropospheric ozone concentration is low. Moreover, we can distinguish stratospheric ozone from tropospheric ozone by observing the formation of the ozone gas.
Why do you think does the troposphere contain over half of all the air in the atmosphere?
The Troposphere contains about half of all the air in the entire atmosphere. Because it i at the bottom, air pressure, or the weight of the air, is greatest in this layer. All the clouds we see and the changes in weather we exper occur in the Troposphere.
How are the troposphere stratosphere and thermosphere important for supporting life on Earth which layer of the atmosphere is likely the most important for life on Earth?
The thermosphere absorbs solar radiation and helps to regulate the Earth's temperature. All layers of the atmosphere are important for supporting life on the Earth, but the troposphere is the most important as it provides organisms with the air they breathe..
Why does Venus have such a great difference in temperature between its no greenhouse temperature and its actual temperature quizlet?
Why does Venus have such a great difference in temperature between its "no atmosphere" temperature and its actual temperature? It has a large amount of greenhouse gases in its atmosphere. Which planet experiences the greatest change between its actual day temperature and actual night temperature?
Why is Mars so cold compared to Venus if both of their atmospheres are made mostly of carbon dioxide a greenhouse gas?
– Mars' atmosphere is mostly carbon dioxide and has a pressure about one hundredth that of Earth. – Mars has a thinner atmosphere and a cold temperature because of the "runaway refrigerator" effect, which is making it colder over time.
Why is convection only in the troposphere?
The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles )causes convection currents, large-scale patterns of winds that move heat and moisture around the globe.
What prevents convection in the stratosphere?
Convection refers to the overturning and mixing of warmer and colder air layers. 2c. The temperature structure of the stratosphere is one of warmer air over colder air. No, convection never occurs in the stratosphere because of this temperature structure.
How does convection occur in the troposphere?
The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles )causes convection currents, large-scale patterns of winds that move heat and moisture around the globe.

The stratosphere has a positive temperature gradient, has generally stable layers of air, has no clouds, except for at the poles, and is fairly dry.
Why do convection currents occur in the troposphere?
The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles )causes convection currents, large-scale patterns of winds that move heat and moisture around the globe.
What is the difference between tropospheric and stratospheric ozone?
Unlike stratospheric ozone, which forms naturally in the upper atmosphere and protects us from the sun's harmful ultraviolet rays, ground-level (or tropospheric) ozone is created through the interactions of man-made (and natural) emissions of volatile organic compounds and nitrogen oxides in the presence of heat and …
What’s the difference between tropospheric and stratospheric?
Stratospheric ozone concentration is very high, whereas tropospheric ozone concentration is low. Stratospheric ozone and tropospheric ozone are the two types of ozone gas in the ozone layer. These two types are named as such, not due to any chemical difference but due to the distribution of the ozone gas.
What is difference between troposphere and stratosphere?
They differ in important ways as well. The troposphere has a negative temperature gradient, is constantly convecting, has abundant clouds and has abundant moisture. The stratosphere has a positive temperature gradient, has generally stable layers of air, has no clouds, except for at the poles, and is fairly dry.
Why does weather occur in the troposphere and not in other layers of the atmosphere?
Gravity, combined with the compressibility of air, causes the density of an atmosphere to fall off exponentially with height, such that Earth's troposphere contains 80% of the mass and most of the water vapor in the atmosphere, and consequently most of the clouds and stormy weather.
Why is the troposphere the most important of all the layers of the atmosphere give three points?
The troposphere contains about 85% of the atmosphere's total mass. Tropospheric processes, such as the water or hydrologic cycle (the formation of clouds and rain) and the greenhouse effect, have a great influence on meteorology and the climate.
Why troposphere is the only layer that supports life?
The troposphere is the only atmospheric layer that can support life. The higher layers have filtered out the harmful radiation, and there are large amounts of water vapor. This is the layer where clouds develop, birds fly, and pollution collects. Yes, the troposphere is where humans most pollute the atmosphere.
Which of the following worlds has the greatest difference in temperature between its no atmosphere temperature and its actual temperature group of answer choices?
Why does Venus have such a great difference in temperature between its "no atmosphere" temperature and its actual temperature? It has a large amount of greenhouse gases in its atmosphere.
Why does Venus have the highest surface temperature of any of the planets?
Venus is so hot because it is surrounded by a very thick atmosphere which is about 100 times more massive than our atmosphere here on Earth. As sunlight passes through the atmosphere, it heats up the surface of Venus.
Why is there so much more carbon dioxide in the atmosphere of Venus than that of Earth quizlet?
The reason why there is so much more carbon dioxide in the atmosphere of Venus than in that of Earth is because at Earth, most of the carbon dioxide that used to be in the atmosphere dissolved into the ocean water and are now in sea sediments.
Why is there so much more carbon dioxide in the atmosphere of Venus than in that of Earth?
Because Venus has such a dense atmosphere which is some 100 times thicker than the earth's. Evidently, Venus is sufficiently close to the Sun that the little carbon dioxide it had in its early, Earth-like atmosphere caused the surface to warm up and leach out more carbon dioxide into the atmosphere.
What is the difference between troposphere and stratosphere?
The troposphere contains most of the moisture, most of the weather, and most of the clouds in the atmosphere. The temperature in the troposphere decreases with increasing altitude. The stratosphere is just above the troposphere. It extends from the tropopause to 50 km above Earth's surface.
Can convection occur in the stratosphere?
The temperature structure of the stratosphere is one of warmer air over colder air. No, convection never occurs in the stratosphere because of this temperature structure.
What occurs in the stratosphere?
The Stratosphere It contains much of the ozone in the atmosphere. The increase in temperature with height occurs because of absorption of ultraviolet (UV) radiation from the sun by this ozone. Temperatures in the stratosphere are highest over the summer pole, and lowest over the winter pole.
