+bassmig Posted September 29, 2007 Share Posted September 29, 2007 yeah, that's right. I actually do have one in my possession. Hoping the prior cacher who moved it from Alberta to NB will log it so I can log it! Quote Link to comment
lewis82 Posted September 30, 2007 Share Posted September 30, 2007 When the glaciers of the last glaciation moved away from Quebec, they formed an enormous water body. It covered all the St-Lawrence valley. With the years it shrunk and disappeared. What is the name of that water body? Quote Link to comment

lewis82 Posted October 1, 2007 Share Posted October 1, 2007 Correct Bullfrog Eh-Team! The Champlain Sea. 2happy2gether, you had part of the answer, but it was a sea because it was directly connected on the Atlantic Ocean. Quote Link to comment
+Bullfrog Eh-Team Posted October 11, 2007 Share Posted October 11, 2007 Sorry about the delay ! But here is the next pub question! When standing at the 'North Pole', what choice of 'basic directions' (no fractional directions) do you have, to move away from the pole ? Quote Link to comment

Now THAT'S outside the box! Nah, that's the box itself which in this case is the whole planet. The pole does run through the planet, and once it leaves the surface it spreads out (assuming we are talking about the magnetic field). So, I would tend to agree (somewhat) with 2h2g... while perhaps not moving closer to the pole, going down would not be moving away from it. Good question, this was. Quote Link to comment

I didn't know this when the question was asked, and didn't look it up. I just used the number you gave (1852m) and divided it into the circumference of the earth at the equator, got a weird number, then tried dividing that by 360. The answer came to 60, which doesn't look like a coincidence to me! Quote Link to comment
+ve1bvd Posted October 12, 2007 Share Posted October 12, 2007 OK, Dano, you got it. Because the Earth is NOT a perfect sphere, the minute of arc is measured at the equator form the centre of curvature. In rebuttal to 2h2g, I think that the poles are at the surface of the earth, so submerging at the North pole would be moving away from it, no? Cheers, Phil/ve1bvd Quote Link to comment

lewis82 Posted October 12, 2007 Share Posted October 12, 2007 The pole is on the sea floor. Ice is not earth! It can melt, and it moves. Also, in 50 years or so there won't be many ice left over the North Pole... But the pole must be somewhere (the sea floor). Quote Link to comment

Also, in 50 years or so there won't be many ice left over the North Pole... But the pole must be somewhere (the sea floor). I would say the pole is actually on the surface (on the ice). Yes the ice moves, so it is "the pole" for the finite time that the plag is placed. Water/ice is the surface of the planet as well as rock. I could argue that trees and muggles also make up the surface of the earth too! Quote Link to comment

What is the name of the ridge, and WHY are the Russians wrong? Isn't the north pole in the North American tectonic plate? Therefore whatever the Russians claim would be false, regardless of the name of that ridge, because the North American Plate is not part of the Eurasian plate.. Quote Link to comment
danoshimano Posted October 16, 2007 Share Posted October 16, 2007 <ahem> There have been breaks of longer than 4 days before. Patience, please. Patience. And everything I think of, I think... wait... that's already been asked. But you can't search an individual thread on the forums. Anyway, on to the question: "Boxing the compass" would be doing what, exactly? Quote Link to comment
+ve1bvd Posted October 18, 2007 Share Posted October 18, 2007 "Boxing the compass" would be doing what, exactly? Going back to my cadet days, boxing the compass means to recite the 32 points of the compass, beginning with North and going clockwise. I was going to try and do it, but I can't remember the last 16 points, East by North, etc. Anyway, each point is 11-1/4 degrees, and can be further subdivided into quarter points, which gives pretty good accuracy, certainly enough to get from A to B. You'd have to be a pretty good steersman to be able to hold a sailing vessel to a quarter point of the compass... cheers, Phil/ve1bvd Quote Link to comment
+Couparangus Posted October 18, 2007 Author Share Posted October 18, 2007 (edited) I do believe VE1BVD has it right, Dano to confirm! I do like Juicy's question so I hope it gets a chance to be asked. Cheers! C-BM-A ! Edited October 18, 2007 by Couparangus Quote Link to comment

+ve1bvd Posted October 20, 2007 Share Posted October 20, 2007 OK, here's another quickie... In terms of terrestrial navigation, what is the difference between a great circle and a small circle?

One is a great way of navigating, the other is a disappointment to their parents, can barely find their way down the road, and is having problems with the canadian revenue agency.

QuigleyJones Posted October 21, 2007 Share Posted October 21, 2007 Oh dear me, think Quigley think. If I recall correctly a great circle goes through the center of the earth. Or better put the center of the circle is also the center of the earth. And a small circle... doesn't Quote Link to comment

Phil/ve1bvd Sounds like old Native American talk for the sun and the moon, although I'm not so sure one would want to use the moon for navigation. Or maybe it depends on how much longer one leg is then the other: a greater difference would mean you'd walk around in bigger circles. Quote Link to comment

A great circle is one drawn upon the surface of the earth whose plane passes through the centre of the earth. A small circle is any other circle drawn upon the surface of the earth.
