Top 10 Proofs the Earth is Not RoundWe know Earth isn't flat, yet while some people today still think Earth is flat, there's also people convinced Earth is round.
Yet it looks round on NASA photos, but looks are deceiving.
We do know now that Earth is neither flat nor round, but a complex nugget that's squashed at the poles and wider in the middle, yet constantly changes shape.
Here are proofs why Earth isn't round.
The Top Ten
Greg... you have had controversial opinions over the years, but YOU. HAVE. GONE. TOO. FAR. The earth is round, and just because it's a elipt, doesn't mean it's as flat as today's TVs.
It's not exactly round as a ball, but it is 3-D, and there's no denying the fact.
It STILL is round, just not a perfect sphere.
This subject is still relevant?
Apparently. Would be interesting to see what's going on in these people's heads to think the Earth is flat.
We have mountains throughout much of our Earth, the Rockies, Smokies, Swiss Alps, the Himalayas and such.
We have Mt. Everest, which is 8,847 m tall(originally 8,848 m tall lost 1 meter due to the Nepal earthquake), Mt. Denali (McKinley) in Alaska, 7,013 m 44 cm 8 mm, the Matterhorn in Europe that's 4,478 m 12 cm 16 mm.
Yet we have volcanoes as well, including Mt. Vesuvius, Krakatau, Chimborazo in Ecuador, which is the highest peak from Earth's center, at 6,384 km 400 m from Earth's center with its 6,263 m height from sea level (due to its 21 km 384 m 70 cm bulge at its equator from rotation), as well as Mauna Kea, which is 4,207 m 30 cm from sea level and over 10,000 m from base (taller than Mt. Everest but a volcano).
A sphere cannot have any mountains or bumps while Earth does as well as an equatorial and tidal bulge.
Earth is so big that these mountains don’t really affect its overall shape.
The truth is that a sphere is a 3-dimensional figure where every part of the surface is equally distant from the center.
That means any variations or mountains of even a SUBATOMIC particle length disqualifies the figure from being a sphere.
Sorry if I had to be harsh, but I was making a clear point.
A sphere cannot have any variations in its texture or distance.
Plus the equatorial bulge is a greater length than the tallest mountain or deepest trench.
There are trenches throughout Earth, including manmade trenches made during wars, yet we have the Mariana Trench in the Pacific, which few people dived in and 1 unassisted (James Cameron).
The depth of the Mariana Trench is 10,994 m(10.994 km), so if Earth were the size of a billiard ball, that area would be like the depth on 320 grit sandpaper.
A sphere doesn't have pits or bumps, but Earth does, and that's another reason it's not quite round.
People are still arguing about this...in 2019?
We know our axis is titled by 23.44392911°, but it does turn around like a top, in an effect known as precession, which takes 25,700 years, and is the reason Polaris isn't always the north star.
This effect can only be achieved on an object that isn't spherical, yet since Earth is fatter at its equator and has geology, and along with the gravitational pull from the Sun, Moon, Mercury, Venus, Mars, Jupiter and its moons, Saturn and its moons, Uranus and its moons, Neptune and its moons, and even the asteroids and dwarf planets along with comets, other stars and galaxies, Earth's axis slowly drifts or wobbles in a 25,700 year cycle.
This effect doesn't work on a sphere, but it does on an asymmetrical object including Earth, and is further proof Earth is not round.
We all know the Grand Canyon, 2,600' deep, yet there are many canyons such as Logan and Bryce Canyon, Canyonlands, Capitol Reef in Utah, Copper Canyon in Mexico, Kings, Sequoia Canyon in California, Black Canyon of the Gunnison in Colorado, and Death Valley in Arizona.
Canyons are another thing that prevents Earth from being round as spheres don't have any marks or holes or bumps.
While we have mountains, trenches, canyons, pits, craters, and an equatorial bulge that makes Earth 42 km 769 m 40 cm fatter at its equator due to centrifugal force from its 23 hour 56 minute 4 second 100 millisecond rotation, there are tidal bulges caused by our Moon and Sun and slightly from the other planets and even distant stars and galaxies that cause our oceans to rise an fall, usually by 3m at its maximum, though our surface is tidally bulged too, by at least 30 cm, which is nearly 1'.
That's another reason Earth isn't round.
Don’t think of Earth as if it were are perfectly round sphere. Think of its shape as if you were to take a large sheet of aluminum foil and crumple it up into a tight ball.
More like if you do all that and then squash it.
Earth is wider in the middle than the vertical diameter because of rotation.
Believe it or not, there are craters all over Earth, though many are worn away by tectonic activity, but some still do remain present, such as the Arizona crater, which is nearly 3/4 of a mile in diameter, along with the Chixulub crater that was from the comet that killed dinosaurs (though some were believed to have survived and evolved into birds and present day reptiles), yet there's the Chelyabinsk crater from the meteor that exploded there in 2013, and recently, a new crater was discovered in Greenland in 2018 from an impact that scientists believe was responsible for the last ice age.
But again, craters are deviations from sphericity, disqualifying Earth from being round.
Earth's shape has been thought of as different concepts over years, such as the flat Earth concept, where Earth looks flat to people living on it, yet Earth has been thought of for a while as a sphere, which is a simple model of Earth, but however doesn't account for the geology and the fact that Earth bulges at the equator due to centrifugal force from its rotation.
Yet Sir. Isaac Newton guessed Earth was an oblate spheroid, a figure that's flattened at the poles and bulged at the equator, so that its bigger in the middle.
He was right for the most part, except that Earth's geology, tectonic activity and tidal bulges keep it from being a perfect spheroid as well.
The shape has been a controversy for many years, modern technological developments have furnished new and rapid methods for data collection and since the launch of Sputnik 1, orbital data has been used to investigate the theory of Earth's ellipticity.
Now with the help of GPS, scientists created a model called ...more
Earth's surface appears stationary, but it's constantly moving in random directions, pushing, grinding, squeezing, pulling, thrusting, in pieces called plate tectonics, showing us Earth isn't entirely solid, but a complex bubble with semi-liquid and solid layers, along with a strong core at Earth's center.
The asthenosphere is heated by Earth's core and generates the tectonic movement that is responsible for earthquakes, volcanoes, mountain formation, and also affects the weather and climate, and all lifeforms on Earth.
It shows us Earth's shape is always changing, which a sphere doesn't.
Earth is land and oceans, so not all of Earth is covered in liquid water, due to is geological terrain, but if Earth were round, we'd have no mountains or other features, and if we still had oceans, we'd be covered entirely in them, so that there's no land over the water on Earth, making it entirely flooded.
But also assuming if Earth were really round, the ocean layer wouldn't have any waves or currents, so that would be perfectly smooth as well.
