How much does the earth curve over 100 miles?

Last Updated: 14th April, 2020

Using the Pythagorean theorem, that calculates toanaverage curvature of 7.98 inches per mile or approximately8inches per mile (squared).

In this way, how much does the earth curve in 6 miles?

However, it turns out that while the earthdoescurve 8 inches in one mile, it does not take9miles to curve 72 inches. To show this, let usreturnto the Pythagorean Theorem method used by Harley, butusing6 feet for the curvature.

Also Know, does the earth drop 8 inches every mile? The “eight inches per mile squared”isa rule of thumb to determine the drop height due tothecurvature of the Earth. It does not account fortheobserver's height and atmospheric refraction. The“8inches” rule is also an approximation. Itremains usableuntil up to about 100 miles.

In this way, how far can you see with the curve of the earth?

The old saying turns out to be just about true. Forasix-foot tall person, the horizon is a little more than 3 miles(5km) away. Geometry tells us that the distance of thehorizon– i.e. the farthest point the eye can seebeforeEarth curves out beneath our view – dependssimply onthe height of the observer.

How many inches of curvature is a mile?

Most sources consider 8 inches per mile asthemost accurate estimate. It means that for every mile ofthedistance between you and a second object,thecurvature will obstruct 8 inches ofitsheight.

Can you see earth curvature?

It is possible to see the effect ofthecurvature of the earth from sea level(shipsdisappearing over the horizon). To actually seethecurvature directly (ie to be able to see thehorizonas an arc, rather than a straight line) requires an altitudeofover 50,000 feet.

How far can you see at sea level?

Boat captains say, on average, you can seeshipson the horizon or land at about 12 miles. A rough formulaat Examples: For an observerstandingon the ground with h = 1.70 metres (5 ft 7 in)(averageeye-level height), the horizon is at adistance of4.7 kilometres (2.9 mi).

Can you see the curve of the earth from Everest?

On Mount Everest, an observer sees thehorizonroughly 230 miles away. The Earth should curve35,000feet. If you're at a high altitude and looking atthehorizon from side to side and seeing a couple hundredmilesof horizon it curves 8 inches per mile.

How far can you see on a clear day?

How far can we see if unobstructed? Dust,watervapour and pollution in the air will rarely letyousee more than 20 kilometres (12 miles), even on aclearday. Often, the curvature of the Earth gets in the wayfirst– eg at sea level, the horizon is only 4.8 kilometres(2.9miles) away.

What is the formula for curvature of the earth?

Using the theorem of Pythagoras a2=39632 + 12 = 15705370 and thus a=3963.000126 miles. Thus your position is 3963.000126 - 3963=0.000126 miles above the surface of the earth.0.000126miles = 12*5280*0.000126 = 7.98 inches. Hence theearth'ssurface curves approximately 8 inches in onemile.
