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.
How is earths core apparently similar to some iron meteorites?
The Earth's core contains a lot of iron and nickel like a meteorite, it's why we have a magnetosphere which protects us from the sun's solar radiation (most of it)....As long as the core remains molten and in motion it'll continue to generate magnetism, otherwise we'll end up like Mars.
When rain does not fall for a long time?
It is called a drought when rain does not fall for a long time.
What type of radiation is reflected away from the earths surface?
Long-wave radiation and visible light.
How long is Earths day?
24 hours its not actually 23 hours 56minutes 4.1seconds
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 does it take to dig to China from here?
Well considering you would probably hit the earths core before you reached china, im guessing a while Well considering you would probably hit the earths core before you reached china, im guessing a while
Is the shadow of the moon always long enough to reach the Earth?
Yes, the shadow of the moon is always long enough to to reach the earth. In fact the shadow is long enough to reach the earths core.

How long would it take to dig a hole to the core?
it would take you 300 days to dig all the way down to 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.
Can you land on Jupiter's core?
No. The heat and pressure would destroy any vehicle or probe long before it reached the core.
What is earths geography?
'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.

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.
What does a liter of water weigh in space?
Weight depends on gravity. People seem to think there is no gravity in space yet the earths gravitational pull is quite strong for quite long. Think of the moon, its pulled by earths gravity long after our atmosphere gives way to the vacuum of space. A liter of water would be the same weight in space and would only fade over long distances. As a side note space begins at like 60-70 miles above the earths surface. If you took a space ship up 120 miles (well into space) and parked it, you would promptly fall back to earth like any object dropped from a height. Lack of atmosphere implies nothing about gravity.
