Very true.

It might help if you read up on the details of plate tectonics a bit more.

You should talk to a academic advisor in the Geology Dept of the University that you would like to attend.

A fire tornado, fire whirl, fire devil, etc is like a tornado but made of fire instead of air. As the heated air from the fire rises, strong air currents cause the air molecules to spin which shapes the flame into a tornado.

Just a couple of tidbits I've read. At the Yucatan (Chicxulub) Crater some of the samples providing evidence of an impact included shocked quartz, tektites, and a gravitational anomaly in the area. Visible outcrops of the impact include cenotes which outline the crater's original impact rim. Cenotes are the gradual dissolving of upper limestone layers overlying broken-up rocks, or breccia. So on the contrary of the crust being filled in, the outline of the crater is actually eroding.

Once you accelerate, but whatever means, to any speed in outer space, you will continue at that speed indefinitely, until you crash into something.

 

The rarified atoms in outer space will very slightly slow you down with a tiny amount of friction, but the stopping distance will be very, very long.

 

So how do you dodge a bullet on your way to another star traveling at 10%C?

So if an object begin accelerating by propulsion, even after the propulsion is stopped, it would continue at that rate. So if the same force of that propulsion was added once agian, would object's speed then double?

Please, humor me here. A is car is moving through space at a constant rate of 50 mph by accelration on the gas pedal. You the remove your foot from the gas pedal. Does it continue to move at about a constant rate if acted on by minimal outside forces? And if it does continue at a constant rate with out the application of the gas pedal, what would happen once the force of the gas pedal is reapplied to 50 mph. Would the car then go faster, slower, or the same rate?
