The Asteroid That Killed the Dinosaurs Hit in Spring

As you may know, a huge asteroid struck earth around 66 million years ago.  The asteroid was travelling so fast that when it hit, it caused rocks to turn into liquid, and then gas – that’s REALLY HOT.  The gaseous rock rose up into the air, then cooled enough to turn into tiny droplets of very hot glass that rained down on the whole earth.  It’s estimated that the surface of the earth heated up to around 1200 degrees!  Based on some fossils found in North Dakota, scientists tell us that this asteroid struck in the springtime.  You can read all about it here:
