Answer:
How does the speaker know that the lump of metal she is holding is an asteroid?
The patterns formed inside the metal She explains that the rock is older the earth and that it is an asteroid due to the patterns formed inside it that show it contains metallic crystals that cannot be formed on earth but in space where temperatures mean that molten metal takes billions of years to cool.
How does the speaker “hunt” asteroids? Describe how teams of scientists collect data about asteroids.
The speaker works with astroids she attempts to search for them for scientific use. She analyzes how long ago these rocks were coming acrost the earth. How many are in the universe.
Both speakers describe the asteroid that hit Earth and caused a massive extinction, including the decimation of the dinosaurs. The speakers describe the size of this asteroid in different terms. Summarize each speaker’s description and explain which one gives you a better picture of the size of this asteroid.
Debris from the impact orbiting around the Earth shielded sunlight, halting photosynthesis.
The impact was so extreme that life at ground zero was vaporized.
tsunamis, landslides, earthquakes, and heat caused by the impact killed organisms near the site of impact.
Does Carrie Nugent agree with Phil Plait’s assessment that we can defend the Earth from asteroids? Why or why not?
It seems as if she does agree. I believe she has strong intentions to defend the earth and to prevent there to be any more extinction for any more animals I believe she cares to explore and recover so if she could find a way to use the asteroids to her advantage she would.

6. How does the speaker know that the lump of metal she is holding is an asteroid?
- The speaker knows that the lump of metal she is holding is an asteroid because the patterns formed inside the metal. She explains that the rock is older than the earth and that it is an asteroid. This is due to the patterns formed inside it. These patterns show that it contains metallic crystals that cannot be formed on earth, but instead in space where temperatures mean that molten metal takes billions of years to cool. The scientists also use representative sampling. This is done when they deal with such large quantities of objects for estimating.
7. How does the speaker “hunt” asteroids? Describe how teams of scientists collect data about asteroids.
- The speaker “hunts” for asteroids by attempting to search for them for scientific use. She analyzes how long ago these rocks were coming across the earth and how many are in the universe. She also is classifying them by color and shape. Some of the objects can be classified into one or more categories and this could lead to disagreements on where they should or should not be listed. Also, the objects can be difficult to see properly.
8. Both speakers describe the asteroid that hit Earth and caused a massive extinction, including the decimation of the dinosaurs. The speakers describe the size of this asteroid in different terms. Summarize each speaker’s description and explain which one gives you a better picture of the size of this asteroid.
- The asteroid hit at high velocity and effectively vaporized. 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. 'It sent soot travelling all around the world.
9. Does Carrie Nugent agree with Phil Plait’s assessment that we can defend the Earth from asteroids? Why or why not?
- I would say that it seems to me as though she does agree. I believe she has strong intentions to defend the earth and to prevent any more extinctions for any more animals. I believe she cares to explore and recover in order to hopefully help find a way to use asteroids to her advantage. On top of that, the object shown is an Irregular galaxy. This can be determined by the fact it has an irregular shape.
