A very LARGE impact such as the one you are talking about, the "fire" is
super heated gases. The incoming meteor is traveling apprx 14,000 to 40,000
miles per hour, thus superheating everything, and a large meteor doesn't
burn up on entry but travels to the earth. Upon impact and the resulting
sudden stop, the inertia of it travels into the earth, creating heat, and
lot's of it. The super heated gases travel outwards catching anything
flammable on fire. Then you have the super heated debris that is ejected
from the impact site that is also thrown out much like hot lava balls. The
gases behind the meteor is also super heated to a state of super hot plasma
generating more heat.

I am watching "Earth: The Making of a Planet" on Nat Geo right now and they

are talking about Chixalub impact and I was wondering, probably something
simple,............................but,

If an asteroid the sixe of Chixalub hits the Earth where does the "fire"
from impact come from?? Is it because it was still burning from entry.
Because I don't understand how 2 object crashing together can create a
flaming impact and "burn" up everything.

Hi

We had a great time at the European Tektite Forum 2011 in Brno, Czech
Republic, hosted by Milan Trnka.

I have uploaded a load of unedited photos onto my site at
http://www.tektites.co.uk/european-tektite-forum-2011.html

I hope to edit the photos and add annotations and descriptions in the next
2-3 months so do check back!

Regards, Aubrey
