The movie got me thinking...what would actually happen? Given some big rock...something maybe as dense as lead...maybe 10 miles across....moving at tens of thousands of MPH...slams right into the Sahara desert.

What happens?
Does the earth's crust just break?
Does the planet get knocked out of its orbit? (and if it does, what happens?)

Does all the heat generated by the impact just incinerate the whole planet?

I'm genuinely curious.  I have a fairly decent grasp of physics, but never really contemplated the result of an impact to the planet like this.

Recall our moon is due to a collision of Earth & a BAM (big-ass meteor/object).

As noted, ask the dinosaurs or folks who witnessed Tunguska impact.

I get all that.  But specifically how. I'm wondering about the exact sequence of events.  The idea of ash clouding out the sun and polluting the air is pretty straight forward. I'm wondering about the damage to planet itself. What happens to the globe?

Chixculub was estimated to be about 6 miles across. Ask a dinosaur how that worked out.

Or calculate it yourself at IC impact effect calculator

From Wiki:

The impact delivered an estimated energy of 21–921 billion Hiroshima A-bombs (between 1.3×1024 and 5.8×1025 joules, or 1.3–58 yottajoules).[25] For comparison, this is ~100 million times the energy released by the Tsar Bomba, a thermonuclear device ("H-bomb") that remains the most powerful human-made explosive ever detonated, which released 210 petajoules (2.1×1017 joules, or 50 megatons TNT).[26] Other estimates find the impact had an energy of 3×1023 joules.[27] The impact created a transient cavity 100 kilometers (62 mi) wide and 30 kilometers (19 mi) deep, which subsequently collapsed to a crater a few kilometres deep, leaving a crater mainly under the sea and covered by 600 meters (2,000 ft) of sediment by the 21st century.[28] In addition, the impact created winds in excess of 1,000 kilometres per hour (620 mph) near the blast's center.[29]

Well we had on 12600 years ago and it knocked out dick into the dirt.

We been crawling back out of the stone age ever since.

So if it was small enough just start crawling back out of the stone age.

But for the most part we be fuqd. Also depends land or water impact?

There are plenty of simulations that have been run, based on what we have seen from large meteorites that have entered the atmosphere.  Anything of any serious size (objects measured in miles in diameter) will be a life extinction event.  You can look up stuff on the web that even offers visual depictions.

For example, remembe the one in central Russia about 5 years ago?.  That sucker measured about 20 feet in diameter, and was coming into the atmosphere at 43,000mph.  It air burst at about 100,000 feet, so there was no major impact, but there was lots of broken glass and the like.

Now that was a TINY object from outside the Earth.  Imagine something that is ONE MILE across, coming in at the same speed.  It's huge mass probably won't airburst, and if it does the fragments will still be gigantic.

Upon impact, large amounts of rock will become superheated and vaporized, and will travel around the globe due to the shockwave.  Whereever that stuff lands, fires will start.   Then the ash will start to fall.   Think of Mt. St. Helens, but MILLIONS of times bigger, with MUCH more ash.

Those living things that burn will be lucky.  The ones that suffocate in the ash will be less fortunate.  Anything that gets past those two death modes will probably starve, since all plant life will die due to the sun being blotted out by airborne dust that lasts for YEARS.

The initial effects depend largely on where it impacts.

Like what if it landed right in the middle of the Yellowstone caldera and they cancel each other out?

ah.. 10 miles dense as lead?
waves yes indeed, crustal waves is what would happen. screw water the crust itself would ripple. nothing would survive is my prediction. maybe some mold, maybe some microbes, for anything larger its curtains.

and yes it might just knock a chunk of the earth into space making one or more moons.. after all its a 10 mile lead projectile...

pretty much everyone would die. if we're really lucky humans as a species would survive with enough people and genetic diversity to repopulate.

look up the toba extinction event, about 70,000 years ago we dipped down to having no more than 20-50,000 population. if the ash had blocked the sun just a few years longer and we probably wouldn't be here now. a planet killer sized asteroid would do substantially more damage than toba did to the global climate.
