Answer:
The largest portion of earth is the mantle... If you're talking about Earth's surface it's water...
Good Luck!!!
OKAY SO, do you have any more info?
When a cold front approaches, air pressure will initially decrease due to the displacement and uplift of warm air.
<h3>
What is a cold front?</h3>
- A cold front is the leading edge of a cooler mass of air at ground level that replaces a warmer mass of air and lies within a noticeable low-pressure trough.
- It frequently originates behind an extratropical cyclone, along the leading edge of the storm's cold air advection pattern, also known as the cyclone's dry "conveyor belt" flow.
<h3>What is air pressure?</h3>
- The air around you is heavy, and it pounds against everything it comes into contact with.
- That pressure is known as atmospheric pressure, sometimes known as air pressure.
- It is the force exerted by the air above a surface while gravity draws it to Earth.
- A barometer is widely used to measure atmospheric pressure.
<h3>What happens when the cold front approaches?</h3>
- When a cold front approaches, air pressure drops initially due to warm air displacement and uplift.
Therefore, when a cold front approaches, air pressure will initially decrease due to the displacement and uplift of warm air.
