If pangaea has been split for over 80 million years ands tigers have only existed for 2 million years then why are there tigers on the indonesian island of Sumatra if most tigers are continental dwellers.
How did they get out there?
Were they introduced or are they native?

Could Atlantis have been an alien space craft? I believe that it is possible and that's why we can't find it. If it was an alien mothership than that would explain why it could have been in many places around the world. It is said to be in many places around the world by different cultures in diferent parts of this planet. Where ever it was and what ever it was it was certainly more advanced than what we are today.
Is there anyone with there own theroies about Atlantis than I would like to hear from them.

I read about this contest for making an automated machine that can dig so much dirt and move it to a certain spot autonomously for some kind of thing they're sending to either the moon or mars and was thinking why not just adapt some kind of machinery that already exists to work autonomously (Like a combine that uses GPS navigation). What would be the best piece of machinery to dig and move lots of dirt?

Since more than 90% of icebergs and ice caps are actually under water even thought they look big from the outside, why is it that if they melt the water level increases?

when ice forms water expands. because of the oxygen. (kind of like when u put a bottle of water in a freezer for too long, it explodes)

so if that ice were to melt it would in fact take up less room would it not?
then wouldnt water levels be decreasing?
