# What is the measure of the height above the surface of the earth?

## What is the measure of the height above the surface of the earth?

The traditional, orthometric height (H) is the height above an imaginary surface called the geoid, which is determined by the earth’s gravity and approximated by MSL.

What is the height of the earth?

Earth’s polar radius is 3,950 miles (6,356 km) — a difference of 13 miles (22 km). Using those measurements, the equatorial circumference of Earth is about 24,901 miles (40,075 km). However, from pole to pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around.

### What is the value of g at a height above Earth’s surface?

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….The Value of g Depends on Location.

Location Distance from Earth’s center (m) Value of g (m/s2)
3000 km above surface 9.38 x 106 m 4.53

Is the height of an area above sea level?

Altitude, like elevation, is the distance above sea level. Areas are often considered “high-altitude” if they reach at least 2,400 meters (8,000 feet) into the atmosphere.

#### How is elevation determined?

Measuring elevation requires a series of complicated measurements. Most scientists today measure the elevation of mountains by placing radios on the peaks of a mountain range, after which, satellites take measurements and determine the elevation.

How big is the surface of the earth?

510.1 million km²
Earth/Surface area

## At what height above the earth’s surface does the force of gravity decrease by 1?

Thus at a height, h=0⋅005RE the acceleration due to gravity reduces by 1%.

At what height above the surface of the earth the value of g is same as that at depth d?

The change in the value of g at a height h above the surface of the earth is the same as at a depth d below the surface of the earth.

### At what height above the earth’s surface the value of g is half of its value on Earth surface given its radius is 6400 km?

If we use 6,371 km as Earth’s radius, the distance above the surface where gravitational acceleration is halved would be 2,639 km.

What is the height of elevation?

HEIGHT is the vertical distance of a point to a horizontal surface. ELEVATION is the height of a point above (or below) sea level. SEA LEVEL or, as it is more usually called, mean sea level, is the average height of the surface of the sea.

#### How do I find the height above sea level?

An altimeter is a device that measures altitude—a location’s distance above sea level. Most altimeters are barometric, meaning they measure altitude by calculating the location’s air pressure.

What is elevation based on?

Elevation is distance above sea level. Elevations are usually measured in meters or feet. They can be shown on maps by contour lines, which connect points with the same elevation; by bands of color; or by numbers giving the exact elevations of particular points on the Earths surface.

## How tall is the altitude of the Earth?

Take the square root of 2 to find r = 1.414 times the radius of the Earth, or 9.05 million meters. That is an altitude of 2.65 million meters, or 2650 km (9.05 x 10^6 meters – 6.4 x 10^6 meters). , M.Sc. Retired as Head of Department of Physics.

How tall are the layers of the atmosphere?

Earth’s Atmospheric Layers. Diagram of the layers within Earth’s atmosphere. The troposphere starts at the Earth’s surface and extends 8 to 14.5 kilometers high (5 to 9 miles).

### Which is the highest point above the center of the Earth?

The highest point above Earth’s center is the peak of Ecuador’s Mount Chimborazo, located just one degree south of the Equator where Earth’s bulge is greatest. | Infographic Text. Mount Everest, located in Nepal and Tibet, is usually said to be the highest mountain on Earth. Reaching 29,029 feet at its summit, Everest is indeed

Which is the highest mountain in the world?

Highest mountain on Earth? The answer is debatable. Mount Everest’s peak is the highest altitude above mean sea level at 29,029 feet [8,848 meters]. Mount Chimborazo’s peak is the furthest point on Earth from Earth’s center.
