GEOLOGIC TIME AND SCIENTIFIC REOSONING
Problem 1: A first look at Geologic Time
1. “Our Story in 1 minute”
What are three impressions you have from this video? (no wrong answer here, just write the three things that
stick out in your mind from the video)
The first forms of life on earth comprised of plant life. It was quite impressive to realize from the one
minute video that the human beings were among the last forms of life to appear on earth and that Dinosaurs and
the formation of mountains appeared before the Homo sapiens (modern man).
2. “The Evolution of Life on Earth in 60 seconds”
What is your impression of Earth’s history from this video? How does that compare with your impression from
the first video?
This video summarizes the evolution of life on earth in a record sixty seconds. It starts from around 4.6
billion years ago when the earth was formed to the formation of the molecules and the first cell organisms here
on earth, to the formation of the first pant life due to the availability of oxygen. It gives a more detailed and
elaborates analysis of life on earth. The main difference between the second video and the first one is that there
is very little activity between 4.6 billion years to around 500 million years. After 500 million years it is when
the Cambrian explosion happened and m...
