What is the sphere that extends from earths core to earths crust?

The sphere that extends from Earth's core to Earth's crust is known as the mantle. It is the layer of the Earth located between the core and the crust and consists of solid rock that is capable of flowing over long periods of time. The mantle plays a crucial role in the movement of tectonic plates and the convection currents that drive the Earth's geological processes.


How long is the core?

From the Wikipedia: "The outer core of the Earth is a fluid layer about 2,300 km ... thick" - With current technology, it isn't possible to go that deep AT ALL.If you just want a calculation based on a hypothetical machine, assume some speed, and then divide the distance by the speed.


What is the structures of the layers of the earth?

The Earth has three main layers: the core (inner and outer core), the mantle, and the crust. The core is composed mostly of iron and nickel, the mantle is made up of solid rock that can flow over long periods of time, and the crust is the outermost layer where we live, made up of solid rock that floats on the semi-fluid mantle.


Which layer makes up the majority of earths interior?

The mantle is the largest layer in the Earth's interior.


How are earths layers different?

The Earth's layers differ in composition, density, and physical properties. The outermost layer is the crust, which is solid and relatively thin compared to the other layers. Beneath the crust is the mantle, which is mostly solid but can flow slowly over long periods of time. At the center is the core, consisting of a liquid outer core and a solid inner core, with the inner core being the hottest and densest part of the Earth.

If you dig a hole from long island NY straight through the earth's core where would you come out?

You would never come out. The Earths core temperature would destroy any implement. Any magma disturbed would fill in any hole, and the Earths gravity would not allow any progress away from the core.

How long would it take to travel through the outer core?

It would be necessary to know at what speed you intend to travel through the outer core.

'Extremely varied' is the short answer. A full answer would require a long essay or a book.

What do scientist believe causes earths magnetic field?

The center core of the earth is solid iron surrounded by molten iron. The center is solid due to the great pressure and the spinning mass of molten iron around the solid iron core creates the electrodynamic effect that causes Earths magnetism. Our moon has little or no magnetic field because its core has long since cooled.


What is the layer below the earths crust called?

the mantle then the outer core then the inner core


If you dug a hole in the Earth and there was no core would you fall right through?

If such a hole could be created all the way through the planet, you would fall in, but you wouldn't fall out. You'd find yourself bobbing back and forth across the center of the earth until you came to rest there. You'd be bobbing for a long, long time, and it would be a long and tiring climb out. Theoretically, if there were no air friction at any point during your fall, and if you could stay clear of the hole itself without employing any friction, you would just barely make it to the opening at the other end. Your wise move would be to grab onto the edge and get the heck out while you can. Incidentally, the above is predicated on both ends of the hole coming out on dry ground. My antipode would be somewhere in the Indian Ocean. Big problem.


How long would it take to fall 15 stories?

This would depend on how fast you were falling. In my opinion, it wouldn't take long at all.


How long would it take in days to reverse the earths rotation?

Umpteen millions even if it could ever happen.
