How close can you get to the center of the Earth?
The average distance to the centre of the Earth is 6,371 km or 3,959 miles. In other words, if you could dig a hole 6,371 km, you’d reach the center of the Earth. At this point you’d be in the Earth’s liquid metal core.
How long would it take to get to the core of the Earth?
The acceleration of gravity is 9.8m/s2 and the radius of the Earth is 6.378 million meters. This means that you would fall through the entire Earth in only 42 minutes! Can you imagine traveling 8 thousand miles in less than an hour? You maximum velocity at the center would be roughly 8km/s (18,000 mph).
How far down is the mantle?
about 1,800 miles
The mantle is more flexible – it flows instead of fractures. It extends down to about 1,800 miles (2,900 kilometers) below the surface. The core consists of a solid inner core and a fluid outer core.
How hot is the outer core?
The outer core, about 2,200 kilometers (1,367 miles) thick, is mostly composed of liquid iron and nickel. The NiFe alloy of the outer core is very hot, between 4,500° and 5,500° Celsius (8,132° and 9,932° Fahrenheit).
Is it possible to travel to the Earth’s Center?
Travelling to the Earth’s center is a popular theme in science fiction. Some subterranean fiction involves traveling to the Earth’s center and finding either a Hollow Earth or Earth’s molten core. Planetary scientist David J. Stevenson suggested sending a probe to the core as a thought experiment.
What is the story I fell to the center of Earth?
In Tales to Astonish #2 (1959) “I Fell to the Center of the Earth”, an archaeologist named Dr. Burke who is on an expedition to Asia travels to the center of the Earth (and also, as he later finds out, backwards in time)–and encounters neanderthals and dinosaurs.
Who first discovered that the Earth has a centre?
It was over 2,200 years ago that the Greek polymath Eratosthenes made the first measurement of the distance around the Earth’s sphere, and it’s been clear ever since that it must have a centre. This doesn’t mean, though, that early philosophers thought of Earth as we do today.
Who is the deepest human who has traveled?
Don Walsh, Jacques Piccard, and James Cameron all share the title for the deepest a human has ever travelled, reaching the bottom of the Mariana Trench (around 11,000 meters or 6.8 miles below sea level).
