We can't draw anything in this forum.
What don't you understand about this assignment?
The length of a football field is 100 yards. When you compare geologic time (4.6 billion years) to the length of a football field, you will find that each yard on the field will equal 46 million years, and each 10-yard section will equal 460 million years. Use this information to complete the activity below.
Create a digital model of a football field. Starting at the left and moving forward in time, label the 10-yard lines in years. Using different colors, draw a horizontal line to mark the beginning and end of each of the following periods and eras [note that the years have been rounded up for this activity]:
• Cenozoic era (65 MYA to present)
• Cretaceous period (146‒65 MYA)
• Jurassic period (208‒146 MYA)
• Triassic period (245‒208 MYA)
• Paleozoic era (570‒245 MYA)
• Proterozoic era (2,500‒570 MYA)
• Archean era (3,800‒2,500 MYA)
• Hadean era (4,600‒3,800 MYA)
