How does temperature vary with altitude?
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.
How does temperature change with altitude in the troposphere quizlet?
The temperature decreases with increasing altitude in the troposphere because these air molecules are heated by the radiation and conduction of energy from Earth's surface and therefore air molecules closer to the surface have higher temperatures than molecules further from the surface.
How does temperature vary throughout the troposphere?
As the density of the gases in this layer decrease with height, the air becomes thinner. Therefore, the temperature in the troposphere also decreases with height in response. As one climbs higher, the temperature drops from an average around 62°F (17°C) to -60°F (-51°C) at the tropopause.
Why does temperature decrease with altitude in the troposphere and increase with altitude in the stratosphere?
The basic answer is that the farther away you get from the earth, the thinner the atmosphere gets. The total heat content of a system is directly related to the amount of matter present, so it is cooler at higher elevations. The heating of the earth itself also plays a role.
How and why does temperature vary with height in the atmosphere?
The air in contact with the ground is warmer than air just above. As you get further and further from the warm ground, the air is colder and colder. This explains why air temperature decreases with increasing altitude in the troposphere.
Why is temperature lower at higher altitudes?
High-altitude locations are usually much colder than areas closer to sea level. This is due to the low air pressure. Air expands as it rises, and the fewer gas molecules—including nitrogen, oxygen, and carbon dioxide—have fewer chances to bump into each other.
How does temperature change as height increases in the troposphere compare this to how temperature changes with height in the stratosphere quizlet?
How does temperature change as height increase in the troposphere? As altitude increases the temperature decreases in the Troposphere. How does temperature change as height increases in the stratosphere? The lower stratosphere is lower in temperature and the upper part is warmer because of the ozone belt.
How does the temperature vary with altitude in Earth’s stratosphere and why does it behave this way?
Temperature in the stratosphere rises with increasing altitude, because the ozone layer absorbs the greater part of the solar ultraviolet radiation. The ozone layer is an absorbing agent that protects life on Earth.
What is the altitude of troposphere?
The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. Almost all weather is in this region. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high.
Why does temperature decrease with altitude in troposphere?
In the troposphere, the temperature generally decreases with altitude. The reason is that the troposphere's gases absorb very little of the incoming solar radiation. Instead, the ground absorbs this radiation and then heats the tropospheric air by conduction and convection.
Why does temperature increase with altitude in the thermosphere?
The thermosphere is the outer layer of the Earth's atmosphere, extending from about 53 miles to more than 370 miles above the surface. The temperature increases rapidly in this layer due to the absorption of huge amounts of incoming high energy solar radiation by atoms of nitrogen and oxygen.
What happens to the temperature in the thermosphere with increasing altitude?
The temperature of the thermosphere gradually increases with height. Unlike the stratosphere beneath it, wherein a temperature inversion is due to the absorption of radiation by ozone, the inversion in the thermosphere occurs due to the extremely low density of its molecules.
What happens to air temperature as you climb to higher altitudes?
As you go to higher altitudes, there are less air molecules pushing down on you (lower pressure). When the pressure of a gas decreases, the temperature also decreases (the reverse is also true – when the gas pressure increases, the temperature increases). Therefore, the air temperature is lower at higher altitudes.
How does temperature change as height increases in the troposphere compare this to how temperature changes with height in the stratosphere?
Temperature varies with altitude, as follows: In the troposphere, temperature decreases as altitude increases. In the stratosphere, temperature generally increases as altitude increases due to the increasing absorption of ultraviolet radiation by the ozone layer.
How does temperature change as altitude increases in the thermosphere?
Temperatures decrease with increasing height as the ozone layer is left behind and the air thins out with increasing altitude. The lowest portion of the low-pressure mesosphere is heated by the warm air of the upper stratosphere.
What causes temperature to decrease with height in the troposphere?
In the troposphere, the temperature generally decreases with altitude. The reason is that the troposphere's gases absorb very little of the incoming solar radiation. Instead, the ground absorbs this radiation and then heats the tropospheric air by conduction and convection.
How does temperature vary in different layers of the atmosphere?
The layers from closest to the Earth's surface to further away are the troposphere, stratosphere, mesosphere, thermosphere (with the ionosphere), and exosphere. The temperature increases at first then decreases, and then begins to increase again through the different layers.
Why does troposphere temperature decrease with altitude?
In the troposphere, the temperature generally decreases with altitude. The reason is that the troposphere's gases absorb very little of the incoming solar radiation. Instead, the ground absorbs this radiation and then heats the tropospheric air by conduction and convection.
Why does the troposphere height vary?
Answer: Since the thickness of the troposphere is determined by the amount of solar energy and the vertical mixing, the tropopause is lower over areas where the air is cold than where it is warm.
Why temperature decreases with altitude in the troposphere?
In the troposphere, the temperature generally decreases with altitude. The reason is that the troposphere's gases absorb very little of the incoming solar radiation. Instead, the ground absorbs this radiation and then heats the tropospheric air by conduction and convection.
Does the temperature increase or decrease in the troposphere?
In the troposphere, the temperature of the air decreases at high altitude, however, in the stratosphere the air temperature initially is constant, and then increases with altitude.
Why does temperature decrease with altitude in the troposphere?
Although variations do occur, the temperature usually declines with increasing altitude in the troposphere because the troposphere is mostly heated through energy transfer from the surface.
Why does the temperature of the stratosphere increase with altitude?
The stratosphere is the layer in the atmosphere above the troposphere. The stratosphere reaches from the tropopause to a height of about 50 km. Temperature in the stratosphere rises with increasing altitude, because the ozone layer absorbs the greater part of the solar ultraviolet radiation.
In which layer does the temperature vary the most?
In the top layer of the atmosphere, the thermosphere, temperatures again rise with altitude due to absorption of ultraviolet sunlight. At the top of this layer, temperatures can vary from 500 C (932 F) to 2,000 C (3,632 F) or higher.
How does the temperature vary in different layer of the atmosphere?
The layers from closest to the Earth's surface to further away are the troposphere, stratosphere, mesosphere, thermosphere (with the ionosphere), and exosphere. The temperature increases at first then decreases, and then begins to increase again through the different layers.
What happens in the troposphere?
We humans live in the troposphere, and nearly all weather occurs in this lowest layer. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. Air pressure drops, and temperatures get colder, as you climb higher in the troposphere.
