The weight of Earth’s atmosphere exerts an average pressure of 1.01 × 105 Pa on the ground at sea level. Use the definition of pressure to estimate the Height of Earth’s atmosphere by approximating Earth as a sphere of radius RE = 6.38 × 106 m and surface area A = 4π R E 2 .

To determine
The weight of Earth’s atmosphere.

Explanation
The average pressure exerted by the atmosphere at sea level is P=F/A=W/4πRE2 and this expression is rearranged for weight of Earth.

Given info: The average pressure due to Earth’s atmosphere is 1.01×105N/m2 and radius of Earth is 6.38×106m .

The formula for the weight of Earth’s atmosphere is,

W=4πRE2P

• RE is radius of Earth.
• P is average pressure exerted by the atmosphere.

Substitute 1.01×105N/m2 for P and 6
