FAQ: How Far Is It Through The Earth?

In general, the planet Earth is a large and complex globe. But, if one were to measure it from one end to the other, how big would it be? How many kilometers (and/or miles) would someone have to go if they just started walking and wanted to get back to where they started? The quick answer is that it is little more than 40,075 kilometers (or just over 24,901 miles).

How far is it thru the Earth?

The equatorial circumference of the Earth is about 24,901 miles in length based on these measurements (40,075 km). Earth, on the other hand, is just 24,860 miles (40,008 km) around when measured from pole to pole – the meridional circumference.

How many miles would it be if you went straight through the Earth?

The short and straightforward answer is 3,958.8 miles, which is the mean radius of the Earth measured in miles. Instead, if you dug a straight line beneath the Earth’s surface, it would take you approximately 3,958.8 miles to reach the core of the world, after which you would have to travel another 3,958.8 miles to get to the other side of the planet.

How many miles deep is the Earth?

The distance between the center of the Earth and the surface of the planet is 6,371 kilometers (3,958 miles), the crust is 35 kilometers (21 miles) thick, the mantle is 2855 kilometers (1774 miles) thick — and the deepest hole we have ever drilled is the Kola Superdeep Borehole, which is only 12 kilometers deep.

Can we dig to the center of Earth?

Despite the fact that it is the thinnest of the three primary layers, mankind have never managed to drill all the way through it. Finally, the mantle accounts for an astounding 84 percent of the planet’s total volume. It would be necessary to drill through solid iron to reach the inner core. This would be particularly challenging due to the fact that there is almost little gravity at the core.

Can you dig straight through the Earth?

Although it seems evident that tunneling through the Earth is a pipe dream, considering the thousands of kilometers (miles) of molten rock that separate us from the opposite side of the earth. The tip of the Kola Superdeep Borehole in northern Russia, which reaches a depth of 7.5 miles below the surface of the earth, is the deepest point humans have ever traveled.

How long would it take to dig to the Earth’s core?

When teaching basic physics, one of the most common scenarios is that of a “gravity tunnel,” which is a tube that has been dug from one side of the Earth to the other through the planet’s center. Approximately 42 minutes and 12 seconds was the answer that was taught for nearly half a century regarding how long a fall through a hole of this size would take.

How hot is it 1 mile underground?

It would be quite hot below earth. The geothermal gradient shows that on Earth, 1 mile underground would be around 40-45 degrees Celsius (75-80 degrees Fahrenheit), precisely as you mentioned, hotter than the surface. Unless your subterranean metropolis is buried behind a layer of permafrost, that would be a significant obstacle to human existence.

How hot is the sun?

In terms of depth below the surface, the Kola Superdeep Borehole SG-3, which was discovered in 1989 and reached a depth of 12,262 metres (40,230 feet), continues to hold the world record for being the deepest artificial point on the planet.

How hot is the center of the Earth?

According to new research, scientists investigating what the conditions in the Earth’s core should be like discovered that the heart of the planet is far hotter than previously thought—approximately 1,800 degrees hotter, putting the temperature at an incredible 10,800 degrees Fahrenheit.

What would happen if the Earth’s core was exposed?

The Earth’s magnetic field will be completely eliminated when the molten outer core cools and solidifies, which will occur a very long time in the future. While that occurs, compasses will cease to point north, birds will be unable to determine where to fly when migrating, and the Earth’s atmosphere would be destroyed.

What is the deepest well in the world?

The Kola Superdeep Borehole had a diameter of only 9 inches, yet it was the world’s deepest hole at 40,230 feet (12,262 meters), making it the world’s deepest hole. It took nearly two decades to reach that 7.5-mile depth, which is only half the distance or less between the surface and the mantle. One of the most remarkable discoveries was the discovery of minute plankton fossils four miles below the surface.
