a base level, 0 feet. everything rises and lowers from that point. its basically a measurement of still water. with waves and tides averaged out of the equation. so if you go under this averaged water level, you are below sea level, and even a foot above this said level is 1 foot above sea level.
A region at or below sea level is called a "low-lying area" or a "depression."
The term for a geographic location above sea level is elevation. It refers to how high or low a point on the Earth's surface is relative to sea level.
The sea level in Galveston, Texas is approximately 0.4 meters (1.3 feet) above the global average sea level. This area is prone to sea level rise and coastal flooding due to its low elevation and susceptibility to storm surges from hurricanes. Local efforts are underway to prepare for and mitigate the impacts of rising sea levels.
The low sea level revealed a land bridge called Beringia between Siberia and the Americas. This land bridge allowed the migration of humans and animals between the continents during prehistoric times.
Amsterdam Schiphol Airport is −4 m meters below sea level (−13 ft).
Less oxygen
Not only climate.Pressure level low than sea level in hills.
It is zero feet above sea level at the Atlantic Ocean.
No

Well, sea level is the standard by wich other things are measured, so zero is the answer. Sea level is sea level. Compared to what?
Cincinnati is 482 feet above sea level.
No, Scotland is not under sea level. The country's elevation varies, with some low-lying areas near sea level, but the majority of Scotland's landmass is above sea level.
In high tides areas, the water level is higher the average sea level. In areas between high tides, low tides from. In low tide areas, the water level is lower than average sea level.
Venice, Italy was originally about 4-5 feet above sea level but is now about level with the sea. During low tide it can be about 2 feet above sea level.
A region at or below sea level is called a "low-lying area" or a "depression."
The lowest point on Earth's surface that is below sea level is the shoreline of the Dead Sea, which reaches approximately 1,412 feet (430.5 meters) below sea level.
