What do the layers of the atmosphere protect the earth from?
ultraviolet
The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.
In what layers of the atmosphere does temperature decrease with height?
Temperature increases as you gain altitude in the stratosphere and the thermosphere. Temperature decreases as you gain altitude in the troposphere and mesosphere. Air temperature varies in complicated ways with altitude.
How does the layers of Earth’s atmosphere affect the planet?
The atmosphere IS THE gases, and gravity is what keeps them from escaping to outer space. Also, with the exception of UV light, which is block by the ozone layer, the magnetosphere is what protects the planet from the most harmful solar radiation not the atmosphere.
How do the layers of the atmosphere protect the Earth describe them and what they do?
The Earth’s atmosphere has four primary layers: the troposphere, stratosphere, mesosphere, and thermosphere. These layers protect our planet by absorbing harmful radiation. Stratosphere 10–31 Miles – The ozone layer lies within the stratosphere and absorbs ultraviolet radiation from the Sun.
What two layers protect the atmosphere?
The exosphere and the ionosphere. The exosphere and the ionosphere are in the thrrmosphere. What two layers protect you? The ozone layer and the mesosphere protect you.
Which layer is the coldest layer of the atmosphere?
the mesosphere
Located between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).
Why does temperature decrease as altitude increases?
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.
Which is the important layer of the atmosphere and why?
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.
Which layer is the most important layer of the atmosphere?
Troposphere
Option a: Troposphere is regarded as the most important layer of atmosphere. It is the lowermost layer of the atmosphere and contains 75% of all air in the atmosphere. Most clouds occur in this layer because 99% of the water vapour in the atmosphere is found here.
What is earth atmosphere discuss the various layers of atmosphere?
The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth’s surface is called the exosphere.
What happens in the lower layers of the atmosphere?
Weather processes take place in the lower layers of the atmosphere while interesting events such as the beautiful aurora, occur higher in the atmosphere. know more about the Earth’s atmosphere layers. By understanding the way in which the temperature of the atmosphere changes with altitude, we can learn a lot about how the atmosphere works.
Which is the most dense layer of the atmosphere?
Earth’s Atmospheric Layers. Diagram of the layers within Earth’s atmosphere. 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.
How is the temperature of the troposphere affected by altitude?
The temperature of the troposphere is highest near the surface of the Earth and decreases with altitude. On average, the temperature gradient of the troposphere is 6.5°C per 1,000 m (3.6°F per 1,000 ft.) of altitude.
Which atmosphere layer is closest to the earths surface?
The layer of the atmosphere closest to the Earth is the troposphere. It begins at the surface of the Earth and extends out to about 4 to 12 miles (6 to 20 km).
