Q:

In which layer is the pressure the highest?

A) Ionosphere B) Stratosphere
C) Troposphere D) Inner core
 
Answer & Explanation Answer: D) Inner core

Explanation:

"Pressure" is the ratio of mass to area. So, for any given area, the one with more mass pressing on it will experience a higher pressure.

 

As you go more deeply into the atmosphere OR earth itself, you are putting more and more mass over you. For the same unit area therefore, the pressure, (mass/area) increases.

 

Hence, the lowest layer will always have the highest pressure i.e, inner core.

This phenomenon is due to tides raised by the Moon which slow Earth's rotation. Because of the way the second is defined, the mean length of a day is now about 86 400.002 seconds, and is increasing by about 1.7 milliseconds per century.
