Earth is a target in a cosmic shooting gallery, subject to random violent events that were unsuspected a few decades ago. In 1991 the United States Congress asked NASA to investigate the hazard posed today by large impacts on Earth. The group conducting the study concluded from a detailed analysis that impacts from meteorites can indeed be hazardous. Although there is always some risk that a large impact could occur, careful study shows that this risk is quite small.
According to the passage, who conducted investigations about the current dangers posed by large meteorite impacts on Earth?
a. Paleontologists
b. Geologists
c. The United States Congress
d. NASA
d. NASA

The body that impacted Earth at the end of the Cretaceous period was a meteorite with a mass of more than a trillion tons and a diameter of at least 10 kilometers. Scientists first identified this impact in 1980 from the worldwide layer of sediment deposited from the dust cloud that enveloped the planet after the impact. This sediment layer is enriched in the rare metal iridium and other elements that are relatively abundant in a meteorite but very rare in the crust of Earth. Even diluted by the terrestrial material excavated from the crater, this component of meteorites is easily identified.
How did scientists determine that a large meteorite had impacted Earth?
a. They discovered a large crater in the Yucatán region of Mexico.
b. They found a unique layer of sediment worldwide.
c. They were alerted by archaeologists who had been excavating in the Yucatán region.
d. They located a meteorite with a mass of over a trillion tons.
b. They found a unique layer of sediment worldwide.

Scientists first identified this impact in 1980 from the worldwide layer of sediment deposited from the dust cloud that enveloped the planet after the impact. This sediment layer is enriched in the rare metal iridium and other elements that are relatively abundant in a meteorite but very rare in the crust of Earth. Even diluted by the terrestrial material excavated from the crater, this component of meteorites is easily identified. By 1990 geologists had located the impact site itself in the Yucatán region of Mexico. The crater, now deeply buried in sediment, was originally about 200 kilometers in diameter.
Which of the following can be inferred about the location of the meteorite impact in Mexico?
a. The location of the impact site in Mexico was kept secret by geologists from 1980 to 1990.
b. It was a well-known fact that the impact had occurred in the Yucatán region.
c. Geologists knew that there had been an impact before they knew where it had occurred.
d. The Yucatán region was chosen by geologists as the most probable impact site because of its climate.
c. Geologists knew that there had been an impact before they knew where it had occurred.

Such a quantity of material would have blocked the sunlight completely from reaching the surface, plunging Earth into a period of cold and darkness that lasted at least several months. The explosion is also calculated to have produced vast quantities of nitric acid and melted rock that sprayed out over much of Earth, starting widespread fires that must have consumed most terrestrial forests and grassland. Presumably, those environmental disasters could have been responsible for the mass extinction, including the death of the dinosaurs.
All of the following statements are true of the impact at the end of the Cretaceous period EXCEPT:
a. A large amount of dust blocked sunlight from Earth.
b. Earth became cold and dark for several months.
c. New elements were formed in Earth’s crust.
d. Large quantities of nitric acid were produced.
c. New elements were formed in Earth’s crust.
