|
temperature to which air must be cooled at constant pressure to become saturated with water vapor and for dew to begin forming on realitively cold surfaces.
|
|
|
Releative Humidity
|
measure of actual concentration of the water vapor componet of air compared to the concentration the air would have if saturated with water vapor.

What is the ionoshpere and where is it located?
|
The ionoshpere is in the thermoshpere. Ionosphere is the outter region of the earths atmosphere and has free electrons

|
|
How many layers does the ionosphere have?
|
It has three layers
|
|
|
Explain in detail the layers of the ionosphere?
|
E-layer was discovered in 1901 when Marconi transmitted a signal between Europe and Nort America and it bounced off. D-layer dissapears at night. F-layer splits into two layers in the daytime and combine at night.
