What is Troposhere?
A layer extending an average of 12 km above Earth’s surface.
What is Temperature inversion?
This occurs when air temperature increases with altitude and the air becomes stable.
What is the Green House Effect?
Is the natural process in which certain gases in the atmosphere warm a planet as they absorb and emit infrared radiation.
How are the atmospheric layers divided?
Based on differences in composition and temperature.;
What gas makes up the majority of the atmosphere?
Nitrogen
What gas makes 21 percent of the atmosphere?
Oxygen
What is the remaining one percent in the atmosphere?
Trace gases-majority is Argon
What is the ozone layer?
