What layer of the atmosphere do plants and animals live?
Troposphere. At the bottom of the atmosphere, where most of the life on the surface exists, is the troposphere. 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.
What is the difference between the troposphere and stratosphere What key role does the stratosphere play in maintaining life on the earth?
Temperatures in the troposphere decrease with altitude. The stratosphere is the next layer up from Earth’s surface. This ozone absorbs some of the incoming solar radiation, shielding life on Earth from potentially harmful ultraviolet (UV) light, and is responsible for the temperature increase in altitude.
What is the relationship between the stratosphere and the troposphere?
Introduction. The stratosphere lies 10-50 km above the Earth’s surface, but can nonetheless have significant influence at ground level. The stratosphere is coupled to the troposphere via interactions between atmospheric waves and the large-scale circulation, which drives weather patterns.
How does the troposphere differ from the stratosphere quizlet?
How does the troposphere differ from the stratosphere? All of the above; The troposphere has higher atmospheric pressure and concentrations of water vapor. Also temperatures in the troposphere typically decrease with an increase in altitude. How do atmospheric conditions affect air pollution?
How does the air in the stratosphere differ from the troposphere quizlet?
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.
What layer do planes fly in?
stratosphere
Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.
Why do we live in the troposphere?
Importance of troposphere to life on earth The study of the troposphere is very important because we breathe the air in this layer of air. The troposphere contains about 85% of the atmosphere’s total mass.
Why are the troposphere and stratosphere so important?
Furthermore, the troposphere is protected from the hard ultraviolet radiation of the Sun by the higher layers of the atmosphere, namely by the stratospheric ozone layer. Because of this protection, many molecules are more stable in the troposphere then elsewhere in the atmosphere.
What is the role of the stratosphere?
The stratosphere is where you’ll find the very important ozone layer. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us.
What’s the difference between stratospheric and tropospheric ozone quizlet?
What is the difference between stratospheric and tropospheric ozone? Stratospheric ozone protects Earth from harmful UV radiation. Tropospheric ozone = smog (toxic). This is all measured throughout the atmosphere vertically in a “column” in Dobson Units (300 DU on average, which is equal to one layer about 3mm thick).
Which is the main characteristic of the stratosphere?
The stratosphere is a very calm & stable layer unlike the troposphere, which is a turbulent layer. This layer is calm and stable because of the absence of any vertical air currents.
What’s the difference between the troposphere and the stratosphere?
Tropopause: The upper layer of troposphere is called tropopause. It is a thin layer and its height changes according to latitudes. In fact, this is a transitional zone which connects the lower troposphere with the upper stratosphere. 2. Stratosphere: It extends up to the height of 50 km.
How tall does the stratosphere have to be?
Stratosphere: It extends up to the height of 50 km. The temperature remains constant up to the height of 20 km, in this layer. Afterwards, it increases upto the height of 50 km because of the presence of ozone.
Which is the lowest layer of the atmosphere?
The atmosphere can be divided into five layers of air. 1. Troposphere: It is the lowest layer of the atmosphere. It extends roughly up to a height of 9-10 km near the poles and about 18 km at the equator. The temperature decreases with the height in this layer.
Which is the most important gas in the troposphere?
Gases: Nitrogen (78%), Oxygen (21%) are the two major gases. The remaining 1% is composed of a number of gases like hydrogen-argon, ozone, helium, carbon dioxide, etc. oxygen is the most vital gas for sustaining life. ii.
