So in a sense bosomtwe crater is the world’s largest puddle

crater!!

Was looking at Google Earth when it was first released, soon after a trip to Montreal. While browsing around Canada, I came upon manicouagan reservoir in Quebec. It was immediately clear that this was an impact crater. Nice to see it again. Cool photos. Thanks.

No Sudbury basin?

Nice pics. Reminds one how the earth is a big fragile space ship and we’re the crew.

What are the odds every “impact” site on every planet (and moon) would be perfectly round? Are we to think all objects striking a heavenly body do so in a perfectly perpendicular fashion? Why aren’t there any elongated craters? Maybe they weren’t caused by “impacts” in the conventional sense at all, maybe the universe isn’t at all like we’ve been taught……. Free your minds sheeple…….

More accessible than the Manicouagan crater in Quebec, Canada, is the Charlevoix crater impact area, along the St. Lawrence Seaway, around Baie St. Paul. Link attached

Motorat, it is not that the meteoroid, asteroid or comet is perfectly round it is just that circle is the shape causes by the impact. A bit like droping any object into still water causes circular ripples.

Motorat - it’s not like dropping a rock into mud. These bastards carry a tremendous kinetic energy, and when they hit, they vaporise - they’re like artillery shells or nuclear warheads. And, like such weapons, the impact crater is defined by the explosion; the cloud of superheated gas and vaporised rock that expands at an equal speed in all directions. Hence, in almost all cases, a circular crater.

Sheeeesh, don’t you infidels know anything? Those craters are from when that alien dude killed all his hostages using thermonuclear weapons a looong time ago. Just ask the Scientologists, they will tell you all about it!!!!!

Motorat,

If you factor in the effects gravity, the odds of an impact being very far off perpendicular to the surface are minimalized. The odds of a tangential impact leaving a long scar are virtually nonexistent.

Besides, that, the Manxor Ritilian’s would never leave such an obvious sign of their existence.

Drop any size/shape of object into a pile of dirt/mud/water and tell me what you see, a circle? Bravo…
Who gave forest gump internet access?

Sort of what I expected, schools don’t teach people how to think critically anymore. Next time you see a meteor streak across the sky at 25,000 MPH (assuming you know how to look up) try to imagine gravity (a weak force) causing it to do a 90 degree turn and landing on your Neanderthal brains…… Not quite the same as dropping something is it? Take a physics course you freaking morons.

Motorat - like I said, yes; it’s not like dropping something. These are kinetic impacts - most of the mass is converted into energy and it’s this expanding fireball that defines the crater. Converse to ‘Motorat, you are a disgrace to humanity’s’ explanation, it’s nothing like dropping a rock into a pond (unless these rocks have the habit of exploding upon contact with water.) Actually, you’re kinda right - if you have shallow enough angle of incidence the impactor can bounce and shear and you get a series of smaller craters that could be read as an elongated groove - http://www.planetary.org/blog/article/00000340/ for further reference.

Motorat, your skepticism is commendable and indeed lunar craters were thought to be volcanic in origin, due to their roundness, since there is no reason to believe impactors would always strike perpendicularly. However, the typical velocity of an impacting asteroid or comet is greater than the escape velocity of a planetary body, i.e. greater than 10 km/sek, so the kinetic energy released upon impact is in fact GREATER than when the equivalent mass of TNT is detonated. Thus, in an impact, an explosion occurs and the resulting crater is between 10 and 20 times the diameter of the impactor, obliterating any signs of an oblique initial crater. The appropriate lesson here is therefore not to free one’s mind (from the confines of facts and reason, perhaps?) but to examine things in detail before exclaiming the ignorance of others

You all try to tell that to the next rock coming down on us.

Nice post.

Just anothe big one.

Awesome pictures! The picture from the ISS is my favoured What a large crater!

Hey.. isnt there one massive crater- like the biggest.. that cant be seen from space?? Yukatan Pen in Mexico.. half land and half in the water.. the one they think really wiped out the dinosaurs.. It was found this century mapping the ocean floor or something??

The Sudbury basin isn’t entirely round, it is elongated. It’s also a pretty kickass crater. Northern Ontario! whoo!

Kitty - The Sudbury impact structure is about 1.85 billion years old and has been greatly altered by geological forces in the intervening years. Like all high energy impact craters it was nearly certainly round when formed. As it stands the Sudbury structure is thought to be the 2nd largest impact crater currently known with Vredefort being the largest.

i cant see picturrrrrrrr duhhhhhhhhhhhhhhhhhhh

Yeah right, objects don’t have to be round, the lines don’t have to be perpendicular, hitting the soil is like hitting the water… they completely ignore basic principles like liquid and solid are two different states of matter and therefore have different properties, forget that water has something called Superficial Tension, which binds the molecules together, lol, they prefer to change all physical laws and logic than to accept that they’re wrong, some people are just that dumb.

trekkari, comparing meteorites with tnt is an awful bad example, for as far as we know they don’t come packed with powder. In fact, if you study the rocks they are composed of many different particles of different masses, so that upon an explosion they would expand at different rates creating deformed holes. So, examine things in detail, please.

Tom Morgan, if the mass was converted into energy then there would be nothing left to make the hole, the incandescent ball of fire would just turn to dust before it could even get close to the ground: http://www.youtube.com/watch?v=5S3WfNDD59Y

Yes, the holes on Mercury, the Moon and Mars were not caused by impacts, they are too perfectly spherical, asteroid 253 Mathilde and Martian Moon Phobos testify to that, they have such huge craters that no impact could have done that without destroying them or pushing these bodies out into deep space.

I had heard that the gulf of mexico it self was a crater….
Is this a possbility you think?

i cant believe crater lake in oregon isnt on here… it makes a couple of these look loke pussies… hehe

i printed these pictures for my science project.

what about st magnus bay in shetland?is it an impact crater?if so,how old is it?

nice post.

Why people who sale drugs, abuse children, etc get jailed, while scumbags like Motorat(maybe a teacher) continue to poison peoples brains, getting rich from selling their books. Who’s doing more damage to society? Simple drug dealer or serial brain poisoner???
