What is inside core of earth ? Has somebody tried for drilling a hole from one side to other side ?

Question

I am curious to know about - what is inside core of earth. I mean, below seas, plains, hills etc. - if we go in digging say upto 10 or 100 Kms., then what will we find ? Is it possible to drill a hole - (I mean - just like drilling like a round ball - from top to bottom ? - in earth.? Has anybody gone inside earth - if so, upto what depth - and what were his observations - like - temperature, humidity, atmospheric pressure, value of gravity (g) etc. etc.

Answer 1

there is a Japanese research vessel that will for the first time be able to drill to the mantle. we have not yet been able to drill to the outer core, which is molten. the inner core is speculated that it is under such intense pressure that it remains solid. that is just a theory from scientists. and we dont really know.

Answer 2

The earth is made up of three layers, the inner most is called the core, next is the mantle, and finally the crust is on the outside. Current drilling technology only allows us to penetrate into the crust, but not through it. If you drilled far enough you would run into magma (lava) at which point your hole would no longer be a hole, but a volcano. The inside of the earth is hot liquid rock and metal so you can't really drill through it anymore so than you could drill through water or orange juice.

Answer 3

There is magma (lava), then liquid iron, then solid iron. The crust is several miles thick, and we've only been able to drill a couple miles down with a 2-inch bit. You should watch "The Core". It's some good science fiction as to how they get to the earth's core, but it has some truths about the Earth's makeup (geology).

People used to believe the Earth was hollow and inside a whole other civilization of people lived inside.

Answer 4

A huge ball of metal. 100 kms is a very small distance when we talk about the size of the Earth. In fact the radius of Earth is close to 6400 kms. And you have to double it to get the diameter.
To go to the center of the Earth, you would require engineering that has not been invented yet. Any kind of vessel that tries to go inside will be crushed like a can of pepsi, by the extreme heat and pressure inside the Earth . But if such a vessel could be made that could survive to the center of the Earth, it would be a scientist's dream.

Answer 5

Inside the core is molten Iron it rotates and swirls has cool spots but is liquid. The iron core gives us magnetic poles. You cannot drill to the core, first there is not a drilling rig big enough and secondly it is far to hard and far to hot. Even the most technologically advanced diamond tipped tungsten carbide drill bit last only a few hours once you get down to around 8000m

Answer 6

The earth's core is made up of molten iron. It's impossible for someone to drill a hole from side to side cos' you drilling machine will melt halfway due to the heat.

Answer 7

Below the crust is magma. It's impossible to drill through because it's hot liquid. I think the farthest down any drill has gone was like 12km in 24 years.

Answer 8

Hi,

At the center of the Earth there is magma which is what the same that erupts in volcano.

The center of the Earth is called Core and it is so hot that nothing yet can pass through it.

Answer 9

just about speaking, you won't be able to do it. Impractically speaking, ignoring a million and a 1/2 factors (air resistance, temperature, drag, rotation, if the hollow is exactly by the middle, etc. etc.) oscillation will ensue, the position an merchandise dropped by will fall by to the middle of the earth, the position this is acceleration will be 0, decelerate until eventually it reaches the different section, and then fall decrease back by...a era of about forty 2 minutes for one oscillation.

Answer 10

The inner core of the earth is comprised mainly of iron, and quite a bit of it is magnetic, thus the Van Allen Belt.
