How are fossils formed and why rare Continental drift theory and evidence to support it..?

Question

Give a good answer please!!

Answer 1

The shore rocks of Nova Scotia match the shores of  Aftrica in a certain kind of rock and ancient fossils type and age....enough to be linked as once being the same coastline.

Answer 2

Water in time, left in free gravity space, sedimentates, salts join with other salts, minerals with like minerals, etc.. After thousands of years a firm layer of these sediments breaks off of this 'submersed' body and breaks the surface where it can dry out and attract other, now floating minerals and salts, etc. causing it to increase.  Now after again a very long time this upper crustial body cracks and some chunks re-submerges which causes massive waves and stirs up silts and sand, etc.  The creatures that were residing in the Oceans are 'surged' over mountains into the inlands to mix with the creatures there, where they all eventually die and are buried under Tons and Tons of this debris, under pressure for a very long time.  During this time these creatures are fossilsed not unlike petrified wood, molecules exchange, salts for salts, minerals for minerals, etc.  Now Creatures that could breath under water of course would die quickly because of the silts and such, but the creatures that could swim and breath at the surface could survive a bit longer, never the less still succumb to death because of lack of food, and they too are covered by tons of wet mud and basiclly Sealed, air tight for a very long time so there could be no deteriation.  Because of  the force of the tons of pressure upon these creatures, we find many "Smushed" looking samples uncovered after the erosion process.   Now if you would like to see somthing very interesting try this experiment.  Take cut outs of continental shaped material and place them on a balloon of approx. same size as Globe.  Slowly deflate and allow the sections to come together and you will see that as the globe Shrinks, these sections will not only come together but will seem to even hug eachother and North becomes East.  Note the original location of the North pole,  it is said to have been about 250 miles off of the coast of Washington.  

If you would like to hear more, i have some very interesting "Experiments" that are not only simple but very cheap, about 5 bucks......have fun       tink

Answer 3

Fossils form in many ways, and the study of them is known as taphonomy.  Generally, it involves remains endlng up in oxygen poor conditions.  Quick burial is one method, but things can also fall into oxygen poor water and lie around on the bed for a considerable time before burial.

As for their rarity, not all fossils are particularly rare.  However, most organisms alive won't end up in oxygen poor conditions, and won't won't fossilize.  Wherever you live, every years incredible numbers of small animals get killed off month in and month out, but the amount corpses you'll see is much, much lower.  Nature has a very efficient recycling squad of scavengers; foxes, undertaker beetles, small squiggly things, bacteria...  Most remains get broken down surprisingly quickly.

Continental drift theory is supported by all kinds of stuff including satellite measurements demonstrating the continents getting further apart or closer together, whichever the case might be.  Then you've got mountain chains running out in western Africa, only for remains of the same one starting again in Brazil.  The same applies for elsewhere.  You also get similar fossils from floras and faunas in places that are now thousands of miles apart.  Again, with reference to western Africa and Brazil, a small Permian freshwater reptile occurs in both areas.  There's no way they could've swum across the Atlantic.

Obviously, those are only brief snippets about issues that are involved and complex.
