According to it, the average elevation on Earth is -2070 m (2070 meters below sea level) and the average height of the exposed surface is 841 m. The site also does a nice job of describing the concept of isostasy mentioned by Prob_Wrong.

Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2.

As you can see, most of New Jersey resides at, or less than 500 feet above, sea level. From sea level at the Atlantic Coast and Delaware Bay, the land rises to the northwest of the state. New Jersey elevation map, Courtesy of Maps.com.

Today, sea level is 5 to 8 inches (13-20 centimeters) higher on average than it was in 1900. That's a pretty big change: for the previous 2,000 years, sea level hadn't changed much at all. The rate of sea level rise has also increased over time.

Hills are higher than plains, but not as high as mountains. You can go up a hill and come down a hill. They are a few hundred metres high. You can't go up a plain, because it's a large area of flat land where there are neither hills nor mountains.

Clouds are generally encountered over a range of heights between the ground and about 60,000 feet. By convention, the atmosphere is vertically divided into three levels: high, middle and low.

The elevation of an object is it's height above sea level. Sometimes elevation and altitude are using interchangeable, however, altitude is the vertical distance between an object and the earth's surface. ... Relief is the difference in height elevation between geographic features.

Elevation of a point on the earth's surface is the vertical distance it is above or below mean sea level. The relief of a place is the difference between the highest and lowest elevations in an area. A relief map shows the topography of the area.

The depth (distance from top to bottom) of the atmosphere is greatest at sea level and decreases at higher altitudes. With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing altitude.

Most geologists classify a mountain as a landform that rises at least 1,000 feet (300 meters) or more above its surrounding area. A mountain range is a series or chain of mountains that are close together.

In Minecraft, altitude is commonly expressed as the number of block layers above the bottom of the game environment, which is layer zero (0). For instance, sea level is recognized as block layer 62, and clouds appear at layer 127.

Earth's atmosphere is about 300 miles (480 kilometers) thick, but most of it is within 10 miles (16 km) the surface. Air pressure decreases with altitude. At sea level, air pressure is about 14.7 pounds per square inch (1 kilogram per square centimeter).

Relative sea level (abbreviated as RSL) is defined as the sea level that is observed with respect to a land-based reference frame. It is often contrasted with eustatic sea level, which is a measure of the total mass or volume of the oceans.
