stratosphere
How does it differ from the troposphere
it is located above the troposphere, has a temperature where temperature increases with altitude.
What is the mesosphere
the third layer of Earth's atmosphere, situated above the stratosphere and below the thermosphere.
How do solar radiation and charged particles interact with the gases in the thermosphere to create phenomena like auroras
When these excited gas atoms and molecules return to their normal state
what is the troposphere
the lowest layer of Earth's atmosphere, extending from the surface up to the tropopause
How does its temperature change with altitude
Temperature generally decreases with increasing altitude
how its temperature increases with altitude, its key role in protecting life through the ozone layer
absorbing the Sun's harmful.
Where is it located and what is its temperature?
It is the coldest layer of the atmosphere, with temperatures decreasing with altitude and reaching as low as -90° Celsius (-130° Fahrenheit)
Why does the temperature increase with altitude in the thermosphere?
air molecules directly absorb high-energy
Where is it located
The troposphere is the innermost layer of the atmosphere, starting at Earth's surface.
In which layer of the atmosphere does almost all weather occur
the troposphere
What is ozone depletion and how does it happen?
The thinning of the stratospheric ozone layer
Why is the mesosphere difficult for scientists to study
It is too high for conventional aircraft and weather balloons.
How can the thermosphere have such high temperatures if there's so little gas?
incoming high-energy solar radiation
What does the word troposphere mean
the lowest region of the atmosphere
What are the main gases in Earth's atmosphere
nitrogen (about 78%) and oxygen (about 21%)
What are the main gases in the stratosphere?
nitrogen and oxygen, with very little water vapor
What is the mesosphere's composition
nitrogen (about 78%) and oxygen (about 21%)
What does the name "thermosphere" mean
heat
Why is the troposphere thicker at the equator than at the poles
intense solar heating at the equator
How does the temperature change with altitude in the stratosphere?
The stratosphere gets warmer at higher altitudes due to the absorption.
What are "shooting stars" and how are they related to the mesosphere?
meteors, which are small, rocky bodies from space (meteoroids) that burn up in Earth's atmosphere
Where is the thermosphere located in Earth's atmosphere, and what layers are above and below it?
above the mesosphere and below the exosphere.
What is the height range of the troposphere
6-9 km (4-5 miles) at the poles to 18-20 km (11-12 miles) at the equator
