Answer:
Less
Explanation:
The thermosphere is located above the mesosphere. The atmospheric pressure decreases with increasing altitude.
The atmospheric pressure is caused by the weight of the air above us. The thermosphere has lesser pressure because the air density is low here and the layers above it has lesser mass. Since they no not weigh much their weight cannot create greater pressure.
The relationship between pressure and altitude is
\(P_{h}=P_{o} e^{\frac{-mgh}{kT}}\)
Where
\(P_{o}\) is the pressure at sea level.
m is the molar mass of air
g is the acceleration due to gravity
h is the altitude
k is the Boltzmann's constant
T is the temperature
