Did an asteroid impact cause the extinction of the dinosaurs? Need correct answer
Homework Answers
Yes, because the asteroid hit at high velocity and effectively vaporised. It made a huge crater, so in the immediate area there was total devastation. A huge blast wave and heatwave went out and it threw vast amounts of material up into the atmosphere.

One of the main contributing factors to the extinction of the dinosaurs 65 million years ago was a large comet or asteroid that struck the earth. It threw up so much dust that the sun was blocked for a period of many months. Suppose the asteroid had a mass of 4.0x10e13 and hit the earth (mass = 6x10e24 kg) with an impact speed of 4.0x10e4 m/s. What would be the earth's recoil speed after such a collision? (Use a reference...

1. [12 points] Compelling evidence for the asteroid impact 65 million years ago which triggered the extinction of the dinosaurs was discovery of a thin Iridium-rich clay layer in sediments all around the world. A normal rock sample from the Earth's crust contains less than 1 nanogram per gram (or 1 part per billion) of Iridium, while the Iridium clay layer associated with the K-Pg impact contains about 3 parts per billion. (a) Assume the K-T impactor was a rocky...

Please tell me correct answer and explain!
An asteroid is moving with a speed v in space, very far from any massive objects. Newton's first law of motion says that the asteroid will slow down since there are no forces acting on the asteroid. the asteroid will speed up since there are no forces acting on the asteroid. o the asteroid will continue to move with a speed v since there are no forces acting on the asteroid. the asteroid...

Q1. In the old (ish) movie Deep Impact, an asteroid is headed straight for earth at a velocity of 30 km/s! Astronauts try to save the earth by blowing the asteroid into two pieces. One piece is smaller, with a mass of 2.2 x 1013 kg, and the other is 4.7 x 1014 kg. But.... their mission is not successful, and the two pieces remain on the same trajectory, heading straight for earth. A) After the explosion, the smaller piece...

1)Now, the issue of the effect of carbon dioxide (carbon) is one that is hotly debated. You will find scientific arguments that indicate things are actually worse than the science-based models predict. And, you will find arguments that indicate the opposite. Some of these may not be well supported by science and thus do not hold up under careful scientific scrutiny. Indeed, there is some thought that even if we were to eliminate most people-induced carbon emissions promptly, Earth would...

EXERCISE 18.6 How Quickly Can Humans Hunt a Species to Extinction? Name: Course: Section: Date: The moa, a giant flightless bird, was hunted to extinction on New Zealand in the early 1400s. The human population of New Zealand was no more than 2,500 at the time when the moa went extinct. We can make some simplified calculations to see how many moas were hunted per year (a) Humans first settled New Zealand and began hunting moas in 1314. The last...
