Well, my 6 yr old would like to know how large a bit it would take to
drill to the core of the earth. Who knows this???
Thanks,

Circumference of the earth = ~24,000mi (inferred from west to east coast distance of US =~3000mi transposed to the equator,~4000mi=4 out of 24 time zones= 1/6th of the circumference ~24,000mi.
Radius from circumference: C=2(pi(r)) C=2(3.14r) then r=C/2(pi) or C/6.28 =24,000/6.28=~3821mi. drill bit
Assumes the center of the earth is at the geometric center of the earth (sphere), drilling from 'sea-level'. and wouldn't require a bit to drillthe whole way really, (crust turns to magma a few hundred miles down).
 
really one big rough estimate though, but can't be far off form the astrophysics method, considering.

It might be fun to talk to a well driller someday (as you come across one,
even if it's years from now) to ask questions. or someone who has worked in
a geology lab where they deal with core samples.

The underground of the world is being mapped, gradually, as oil drillers (and
others, I guess) send in their core. When they come to mud or water, they
measure how much pipe went down before they hit rock again, and they pull out
sections of the layers of rock and those (not from EVERY hole drilled, but
from those involved in this) are sent to labs for analysis of the layers. It
helps the oil workers for future drilling, but also helps to show where
underground water and other-stuff are.

Also, drills break. And there would be easier and harder places to "drill to
the center of the earth. It depends what rock is down there, but under ALL
of it there will eventually be some drill-breaking stuff.

Maybe finding statistics on the deepest holes ever dug would be fun.

It's also possible to drill at an angle, or to turn a corner down in there.
Sometimes mining thieves do that--kind of like rustling oil from the
neighbor's mineral-rights claim.

That's probably WAY more than any six-year-old will be interested in, but it
might be a fun ongoing curiosity for the adults.

Sandra, who lives in New Mexico where water is sometimes WAY down below the
ground, and wells for houses sometimes have to be over a thousand feet deep
to get clean, drinkable water. The elevation here is already 5,000 feet,
generally, and I haven't tried those, but I would if I were wanting to look.

Thanks too everyone.
We got out one of the science books we have...  It showed a cut away.  It talked in terms of miles.  That was something he could relate to (That would be like driving to Asheville and back....ect)  He was much impressed.  He thought it was neat about the heat and how it changes the rock, and how small the crust actually is.  We never need dwell on it very long, but when there is an interest we usually try to drop all we can and find an answer.

Do you have your own wells? Do you have to *dig* them yourselves?
Its strange for a city dweller like me, to think that you dont have
water *on tap* provided by council by pipes that run under the
ground.......

People in the country do have their own wells. We had a well when I was
growing up. They're dug by professionals, and there's an electric pump (most
commonly) and they work from inside the house just like any city-water
house--you turn it on and water comes out. But if the electricity goes off
the water doesnt work! <g>

Some people end up getting land where wells can't be drilled. Well, wells
can be drilled but there won't be any water! <g> Up on the sides of
mountains where the water table is way WAY too low, or the rock is way too
hard or somehow else inaccessible. Some get a tank and truck water in. Some
just find they can't live on the land they've bought. But often part of
buying the land is the information about water table.

As far as I've heard, the first water they hit is skipped and they go to the
second or third (for it to be cleaner and less affected by drought).

I'm in Albuquerque, on city water. The purpose of a town seems pretty much
to share water (in the case of small incorporations who are just getting
shared well and sewer, instead of individual wells and septic tanks.

Sandra and Cindy,
Here in New Zealand a lot of country people have water tanks. They
*catch* the rain water and use that. If the tank gets low and there
is no rain, then the water has to be bought. These people have
septic tanks too. It is quite possible that those who live way out
in the country could have wells - but I havent heard of it - but I am
a city girl - unfortunetly.
Cindy your place sounds great - I would love to live there too. I
could cope with everything except SNAKES........ We dont have snakes
in New Zealand.

Our irrigation well (for our neighborhood of 85 homes) is more than 800
feet deep, and it still doesn't supply quite enough water. southeastern
Washington state. The rep from the irrigation department said you can
sometimes drill just a short distance form a great well and come up with
nothing.

I was thinking about the "what's underground" in terms of the recent
earthquake in Puget Sound area and all the different places that it was
felt. It did register around where I live, but I didn't feel a thing.

Wells are fairly few-and-far-between these days here in
the UK, we have enough rain (usually) to keep rivers
and reservoirs well-stocked (scuse the pun) (sometimes
waaaay more than enough, how did Flaxton fare in the
flooding recently?) But there are a few here and
there, in the more remote bits (yes, there are remote
bits of the UK, but not many...) I have heard of
farmers who build ponds and res'es on their land for
their own use get charged by the water companies for
the water they take from the area's supply systems...
they'll charge for breathing next...

I just joined this group. My name is Johanna and live in Tennessee. We have well water and had to drill 235 feet I thought that was a lot, but listening to others comments, I guess we had it pretty good. Our water has sandstone in it so we have to filter, but otherwise it is excellent.

After the Loma Prieta quake some wells around here changed significantly.
Ones that had plenty of water went dry while others got more water.  Then
there were the well pipes which were broken by the land movement.  Of
course Loma Prieta was much closer to the surface than the recent one
in the Pacific NW.

We had our own well when we lived up a mountain in Wales. The water was then pumped across our field and into the house pipes. It was all free.
It also tasted better than that yucky stuff out of taps even if sheep had peed in it :)

Good ol' sheep-pee, good for what ail's ya, eh? LOL

Hi Marianne,
 glad to meet you. We have six children,Cindy-16, Raymond-14,Michael-10, Julian-9, Gabriel-3, and Victoria-2. My niece, Noryanna-10 lives with us also. Our family moved to Tennessee in October of 99 to get away from government control and overcrowding in Massachusetts. We now have ten beautiful acres. All of the children are homeschooled except Raymond who insisted on going to a public school. He is presently regretting his decision. We have homeschooled for three years. I was originally using mostly textbooks, but the more I read about unschooling the more I think it is what our family needs. I have been looking for families who have unschooed succesfully to ask some questions so if yours are mostly grown and gone, maybe you can help me. My biggest fear is government intervention for improper recordkeeping. I know my children are learning every day. Do you keep a daily log of activities? How does the school system in New Zeland keep track of homeschoolers? This year I have given the children more freedom in what they study and learn. I do require bookwork for math and language arts. Otherwise what they learn is at their discretion. TV is kept to a minimum, unless it has something good to learn. My Michael loves the show Bill Nye the Science Guy. Do you use portfolios? we will be going a lot of gardening and landscaping this year. Good hands on stuff. My husband is a truck driver and gone for two weeks at a time. Sometimes that is really hard. One advantage of homeschooling is the kids can go with him sometimes. One on one time with Papi all to yourself for a week or two. How many children get that opportunity? sometimes it is absurd how ridiculous public schools can be. I have to go into my Son Raymond's school tomorrow. He got in trouble for having a rubber band in his hand. Rubber bands are forbidden in the gym room, they can be dangerous you know. He wasn't trying to shoot it or anything, just had it in his hand sort of playing with it while waiting for the bus. So now he has to write 100 times " I will not have rubber bands in the gym room, ever." Can anyone believe this?!  I have a gigantic urge to wear my "Question Authority" pin from my youth when I go tomorrow. Is that sarcastic? I think some of the administration are so caught up in the rules, they can't see the forest for the trees. Have you had any dealings with public schools? How have they been? Do you farm or homestead? We have three dogs, two Great Pyrenees and a German Shephard. I am considering getting a few sheep in the future. We also want to get a few chickens. I can and bake home made bread. What things have fascinated your children?
Johanna

Here in New Zealand you have to apply for a dispensation to h/s your
children. Twice a year you have to sign a document to say you are
still h/s ing.(and to claim the $350 6 monthly *payment* per child
offered to h/s parents).
We have ERO (education review officers)who visit h/s ers to asses
what the children are doing. Actually they asses the parents not the
children. Because of a lack of funding, we dont get many visits from
ERO. Some h/sers never get a visit - others get 2-3 visits. I have
only been h/sing for 10 months and so far have not had a visit,
though I do expect to be getting one soon. I suppose we are very
lucky really. It is reasonable easy to h/s our children here - the
children do not have to be tested and we do not have any set
curiculum to follow as long as the children are taught *as adequetly
and often* as ps children.

I really envy your country living. We live in a suburb of Auckland.
The biggest city in NZ.

Johanna

They actually pay you to homeschool? In US we pay taxes for the school system, but get no benefit. Not even a tax break. I did find out all the state requires is attendance and asesment testing in certain grades.
Thanks for the feedback.

Welcome Johanna!
I am a sahm of 3 wonderful boys. Unschooling has made
a huge difference in the way I parent, and the way we
all live our lives. I am glad of the day I discovered
unschooling.com.
Looking forward to knowing your family.
