How far can you see until the earth curves?

Earth’s curvature The Earth curves about 8 inches per mile. As a result, on a flat surface with your eyes 5 feet or so off the ground, the farthest edge that you can see is about 3 miles away.

Is the earth round or oval?

The Earth is an irregularly shaped ellipsoid. While the Earth appears to be round when viewed from the vantage point of space, it is actually closer to an ellipsoid. However, even an ellipsoid does not adequately describe the Earth’s unique and ever-changing shape.

How far can the human eye see on the horizon?

Also, the higher the observer’s eyes are from sea level, the farther away the horizon is from the observer. For instance, in standard atmospheric conditions, for an observer with eye level above sea level by 1.70 metres (5 ft 7 in), the horizon is at a distance of about 5 kilometres (3.1 mi).

How did Eratosthenes prove that the earth is round?

Eratosthenes then measured the angle of a shadow cast by a stick at noon on the summer solstice in Alexandria, and found it made an angle of about 7.2 degrees, or about 1/50 of a complete circle. Eratosthenes then used this to calculate the circumference of the Earth to be about 250,000 stadia.

How do flat-Earthers prove the Earth is not curved?

The magnitude of atmospheric refraction. Flat-Earthers like to use the visibility of a distant object to prove Earth’s curvature does not exist. Very often, they failed to account for observer’s height and atmospheric refraction, or make other mistakes, like unit conversions errors, distance calculation errors, etc.

How do you calculate the curvature of the Earth in feet?

You can check it out here. Rowbotham states that if the earth is 25,000 miles in circumference then the curvature would be 8 inches per mile. To use his calculation you just square the mileage and multiply by 8. So if you use 3 miles it is 3 squared (9) and multiply by 8 (72), which is 6 feet.

How does the curvature of the Earth affect its climate?

Answer Wiki. 5 Answers. , Environmental Consultant. The curvature of the earth (due to it’s roughly spherical shape with a higher diameter at the equator) in the context of other factors including its axial rotation, solar orbit & axial tilt (its axial rotation is at an angle to the direction of solar radiation) all affect the earth’s climate.

Is the Earth flat or flat?

Sitting for a while by the seashore ought to make it clear the Earth isn’t flat, even if you don’t happen to see a ship go over the horizon. The edge of the discworld Earth would have to be just a few miles away, and there’s no way that the entire, circular world would fit inside the circle that the ocean horizon seems to make.
