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.
