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.
Sea level is a standardized measure based on the average height of the ocean's surface. It typically hovers around 0 feet or 0 meters, and any deviations are noted as increases or decreases above or below this baseline reference point.
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 is approximately 2 meters (6.6 feet) above sea level. The city is located in the low-lying Netherlands, which makes it vulnerable to sea-level rise and flooding.
Less oxygen
Not only climate.Pressure level low than sea level in hills.
It is zero feet above sea level at the Atlantic Ocean.
in the sea
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.
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.
It's a height measurement usually using the sea level as a reference. Low altitude is close to sea level and high altitude is a high above sea level. Answer It's relative. For planes it's anything less than 500 feet off the ground. For orbital space near Earth, it's within maybe 100 miles.
it can be so under ground or low on pressure and be considered below sea level
it is 3700 sea level low
