It has numerous crevices in the face of the Earth as well as the rocks that have been found by archeologists that contain radiation not found on earth and when you find an area that was hit by a large meteor it the debris is spread out over a very large distance showing it had to be broken up and dispersed somehow.

∙ 13y agoThere are many; celestial debris found in ancient rocks, a huge crater off the Gulf of Mexico, the fact the dinosaurs actually died out, plus a mass extinction of dinosaurs, plants and animals all triggered by very much the same things are just a few!

What year did the dinosaur's get killed by the asteroid that hit the earth?
65 million years ago.
Is the dinosaurs ALL wiped out when the large meteorite hit the earth?
According to modern scientific theory, all the remaining dinosaurs went extinct during or shortly after the asteroid hit the Earth 65 million years ago.No evidence of a large meteorite hitting the Earth.
Was caused by fallen debris from asteroid impact on dry soil and rock?
Scientists believe that fallen debris from an asteroid impacted on dry soil and rock caused Earth to form. This is referred to as "The Big Bang Theory".
Did an asteroid hit the US?
Historically, an asteroid that struck the Earth 65 million years ago is one theory for the extinction of the dinosaurs, but that hit in Yucatan (Mexico).
What is the name of the asteroid that will be near earth in 2029?
99942 Apophis is an asteroid where initial observations indicated a small probability (up to 2.7%) that it would strike the Earth in 2029.Later observations concluded that the asteroid would miss the Earth.The chances are now set at a one in 3 million that it will hit Earth.
What natural disaster wiped out half of the earth's animals 65 million years ago?
A large asteroid impacted the earth 65 million years ago, creating the Chicxulub Impact Crater, and killing the dinosaurs.
What did Walter alvarez do afer he found the iridium?
After finding Iridium, now he got enough evidence for his theory. That Iridium was from the asteroid that impacted the Earth and caused dinosaurs to perish.
The mass extinctions that occurred 250 million years ago and 65 million years ago may have been due to gradual process or?
A large comet or asteroid striking earth
What is the correct spelling of the word dinosaure?
The correct spelling of the word "dinosaure" is dinosaur. Dinosaurs once roamed the earth up until about 66 million years ago. A large asteroid impacted Earth at this time and wiped out most life forms, including dinosaurs.

What do scientists believe happened after an asteroid struck earth million years ago?
The dinosaurs died.

What effect did the asteroid hitting earth have on it?
It all depends on the size of the asteroid and the speed. When an asteroid about 6 miles in diameter slammed into the Gulf of Mexico 65 million years ago, it killed off every large lifeform on Earth, including all of the dinosaurs.

What is the gravity pull of the earth on a asteroid?
Most asteroids are located in the asteroid belt, which is so far away from the Earththat they do not experience any measurable gravitational pull from Earth. If anasteroid approaches the Earth, however, then it will experience quite a substantialgravitational pull. Asteroids can weigh thousands or even millions of tons.====================================Answer #2:There can never be any single answer to that question. Just like any otherobject, of course, the gravitational force between the Earth and an asteroiddepends on the mass of the asteroid, and on how far it happens to be fromEarth at the moment.Here is a sample, 'back-of-the-bar-napkin' calculation:-- Assume that the asteroid has a mass that would weigh 1 million tons on Earth.-- Assume that the asteroid is only 10,000 miles outside the orbit of Mars.So, as the Earth and the asteroid both go round and round the sun in theirrespective paths, the closest they can ever get to one another is about33.9 million miles.-- When the asteroid is on the surface of the Earth ... 3,959 miles from the center ...it weighs 1 million tons. Its weight when it's 33.9 million miles away is just 1 million tonstimes the square of the inverse ratio of those distances.(1 million tons) x ( 3,959/33.9 million)2 = 18.35 tonsThat's the Earth's pull on the asteroid, and the asteroid's pull on the Earth,when they're as close together as they can ever be.Mars, being so much closer, and Jupiter, being so much more massive than theEarth, have that much greater gravitational interaction with the asteroid, andpotentially big effects on the shape of its orbit. The problem with that is thatthey may nudge the asteroid into an orbit with a shape that could eventuallycoincide with where the Earth is that day, and could wipe out the remainingdinosaurs.
