Nova Day the Dinosaurs Died
watch the video and answer each number of your responses ONE BY ONE. Some responses can be
answered with a simple value or a few words, while other questions will require a more carefully thought out
response.

1) The video explored numerous lines of evidence (fossils, hydrological and geological processes, and relative
dating) for evolution. Describe how two or more of these lines of evidence supported each other. Clearly
distinguish the lines of evidence in your response.
2) How many species of dinosaurs have been discovered and how long where dinosaurs the dominant major
life forms?
3) What geological period was this and what defines it (may have to google this)?
4) What was the climate like at that time?
5) Briefly describe Hell Creek during the time of the dinosaurs.
6) What is the K-T boundary?
7) Who discovered this layer?
8) What was the element that identifies it?
9) Describe the asteroid (size, size of crater, where it hit, and how it was named).
10) How did the peak ring form?
11) Are peak rings common on Earth?
12) How was sedimentary limestone dated in the peak ring? Is this numerical or relative dating?
13) Explain how some rocks face magnetic north and some face magnetic south in the peak ri1ng.
14) Describe the speed and energy released from the impact.
15) What produced the shocked quartz at the impact site?
16) How did a local impact eventually kill 76% of all life?
17) How long did it take for planktonic life to recover from this event?
18) How did primitive mammals survive these events and how quickly did mammals evolve to be the size of
dinosaurs?
19) How might evolutionary history have differed if the asteroid hit in the middle of the Pacific Ocean?
20) In a few words state the ultimate cause of this extinction event (think big picture
