  • Giant, sunken pieces of an ancient continent from the time of the dinosaurs may have been discovered deep in the Indian Ocean, scientists say.The two fragments, called microcontinents, are possibly leftovers from when India, Antarctica, and Australia were part of a supercontinent known as Gondwana (see a map of Earth during this time.)
  • What the scientists found surprised them. Rather than the normal basalt rock of most seabeds, the scientists pulled up chunks of granite, gneiss, and sandstone—rocks normally found on continents. (See pictures of different types of rock.)
  • Some samples even contained fossils, said team member Joanne Whittaker, a marine geophysicist at the University of Sydney in Australia."It's quite clear that these two plateaus are little fragments of Gondwana left behind as India moved away from Australia," Whittaker said.

    I can't believe that they found chunks of granite, gneiss and sandstone which are supposed to be on continents :)

    That is amazing that scientists found pieces left over from Gondwana and chunks of granite, gneiss and sandstone which are only found on land. Cool! ;)

    That is wierd that they found chunks of granite, gneiss, and sandstone. And that they found remains of a continent!

    That's awesome. Maybe they might find a NEW continent, or maybe one is going to build up!! That would be cool too!

  • Wanted: Garbage collectors in space
  • A sprawling garbage heap floats high above Earth. It contains fragments of broken-down satellites and pieces of used rockets, as well as a few unusual objects like gloves and cameras accidentally dropped by astronauts. The problem isn’t going away; it’s getting worse.
  • The number of pieces of space garbage gets larger every year. Around the world, space agencies worry about the trash because even small bits of litter — no larger than the fingernail on your pinkie — can cause serious damage to satellites or spacecraft.

      Check out the links and let the rest of the class know what they're about! :)
  • Scientists studying rock samples have evidence that gold was delivered to Earth's surface by meteors! The evidence indicates that about 3.9 billion years ago, a huge "firestorm" of meteors brought gold and other precious metals to the planet.
  • anonymous on 25 Nov 11
     
    That's so cool!! :) I wonder how if that every 3 billion years if meteors bring gold down to earth.

    That's awesome, now i wonder if aliens are real!?!? I'm not crazy! :D It's possible, just like how gold was delivered to Earth's surface by meteors is possible! :p
  • Megan Ehman on 26 Nov 11
     
    That is so amazing. I wonder if they will bring gold down to Earth's surface again!
