Sea level (average sea level) is the start point for measuring elevation on this planet and is considered to be the same everywhere. Chicago, however, is not at sea level; rather its mean elevation is 586 feet (179 meters) above sea level.
Mean sea level is the same everywhere. Tidal variations are different in different places. You would need local info for this. The local coastguards could give you this.
No, altitude and sea level are not the same thing. Altitude is the distance of a location above sea level, while sea level is a specific level used as a reference point for measuring elevations. Sea level represents the average level of the ocean's surface.
The same that it always is.. sea level
No
At sea level everywhere on the Earth oxygen makes up about 20% of the atmosphere.
Points that are located at the same elevation above sea level are said to be at the same altitude. points A, B, and C are at the same altitude.
No, sea-level pressure and station pressure are not the same. Station pressure is the atmospheric pressure measured at a specific location, while sea-level pressure is the station pressure adjusted to sea level using a standard formula to account for differences in elevation.
The sea level is the same on both the east and west coast. However the sea level is higher near the poles because of the earth's rotation
Sea level is the same at all places in North America. Choose any beach.
The Atlantic Ocean is sea level everywhere, with slight variances attributed to the moon's gravitational pull.
Sea level is 0 feet, period - that's the reference used for determining land elevation. Sea level is the same in Hawaii as it is in Siberia or anywhere else.
