Earth Sciences & Geology - September 2006

It is a pity that bristlecone pines only go back 5-6000 years (as if that isn't long enough for a tree to live). That age in itself would be grist for the creationists mill, since they can argue that there are no trees older than that because the Earth wasn't created.

So, what about ice cores from Antarctica? One cannot dispute the annual layers in them, surely. How far do they go back - long enough to dispel 6000 years as the age of Earth?

The earths temperature has been steadly rising over the last 15k yrs, long before the industrial revolution. Also, remember that there is scientific evidence to show that the earth has went through several ice ages with 60 k year cycles. If you look at even fossil evidence you'll see that during the permion era florida and most of texas was underwater, as well as many other places around the world. The earth goes through its own seasonal cycle on a scale of thousands of yrs just as it does on a yearly rate.

I have some geological knowledge just from an interest point of view living in a very geologically active country, New Zealand. But I always fall a bit short, when creationists say "give me proof of the advanced age of the Earth".

What I would like is the best possible ammunition to throw at these people. What are the most obvious signs of the age of the Earth? If I quote deep river valleys and U-shaped valleys, they simply come up with the old "they were cut by the Biblical flood".

I would appreciate just your 3 best indications that anybody with eyes could see.

Thanks in anticipation.

Assuming that Earth started life as a very hot place where water could not exist where did all the water which now covers two thirds of the surface come from?

...surely as they are up so high the moisture / water would turn to ice...is this true?
And if this is true, how come aeroplanes can travel through clouds?

Do we replace the oil with anything in order to balance the equilibrium of the planet, such as water or some other substance. I often wonder if the world will tip off balance because we have taken some of the weight out of it.

Given that certain areas of the earth are large producers of oxygen (i.e. Tropical Rain forests) and other areas are not (Moab, UT (desert)), does there exist oxygen gradients between these two sources. How do they equalize? Is it noticeable? And will there be a business in bottling air from Brazil and shipping it to Moab?

If you were in a desert or looking out to sea and everything was completely flat, how far are you able to see? Would there be a difference between the North Pole and the Equator?

It has been over 788,000 years since the last event which should occur approximately every 500,000 years, so it is way overdue. ("soon" in astronomic timescale).
