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)
• Triassic (245‒208 MYA), Jurassic (208‒146 MYA), and Cretaceous (146‒65 MYA)
Periods
• 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)

don't understand what im supposed to do
Your model should be divided into 10 equal parts. Each part represents 460 million years.
Place the different eras in their appropriate places. For instance, the Cenozoic era will be about 14% of the first part.
