I have this project:

Question

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)

I am going to use Google SketchUp, but I have some trouble with the organization. How big should the gaps in each era be? How should I decide that?

Answer 1

Dude I know that you are homeschooled because I have the same thing

Answer 2

I have this as a portfolio on m virtual school.... I don't think this is a coincidence... :/

Answer 3

Virtual School and Also Anonymous, it doesn't matter that he is homeschooled, he still needs help just like everyone else on this site. You really shouldn't discriminate like that. And Anonymous, I'm sorry that no one helped you. I can see that this was posted two years ago and I hope that you figured out how to correctly do this.

Answer 4

I have the same question ugh.

Answer 5

Left goal line is 4600 Mya.
Each successive 10-yard segment subtracts 460 My.
10-yard line = 4600 - 460 My = 4140 Mya
20-yard line = 4140 - 460 = 3680 Mya
30-yard line = 3680 - 460 = 3220 Mya
40-y line = 2760 Mya
50-y line = 2300 Mya
40-y line = 1840 Mya
30-y line = 1380 Mya
20-y line = 920 Mya
10-y line = 460 Mya
right goal line = now (0 Mya)

Now each individual yard segment represents 46 My, so
65 Mya = 46x
x = 65/46 = 1.413 yard segments... so the beginning of the Cenozoic is at the 1.413 yard line at the right side of the field.

Beginning of Cretaceous is 146 Mya, so
yard line = 146/46 = 3.174 yard line on right side of field

Beginning of Jurassic at 208:
208/46 = 4.522 yard line

Is that enough help?

Answer 6

I know how to do all of that but my problem is how do I create the digital model part?

Answer 7

I really don't know it..... I am so sorry! :(

Answer 9

i have the same question i need an answer so bad i love science but im bad at it

Answer 10

Do your own work. We monitor these sites and you will get a zero. Ask your teacher for help

Answer 11

You might choose Word to complete this activity. When you open Word you will want to change the "page layout". Click on the "page layout" tab at the top of your new Word document. Then click on "orientation". Then click on "landscape". That will change your layout so that the table can fit with 10 rows, with enough room for text. Then go to the top of the Word document and click on "insert". You will then click on "table" and add a 10x1 table (highlight first 10 horizontal boxes). Once you create this table you can make it as big as you want so it can fit properly on your page. You will be able to insert text throughout the document, and you should be able to add lines by going to "insert" and clicking on "shapes". Good luck!!

Teacher you look for questions and you are not Real

Answer 15

How do I do the digital model part?

Answer 16

I don't really get it. Very dyslexic when it comes to measurements haha

Answer 17

Teacher is not the smartest guy out there.

Answer 18

Teachers that say that kind of crap on these websites are real doo doo heads

Answer 19

I am old and never had to do this type work. 1962 in 8th grade. How do you do the math to get where the yard on field would be placed? I get that each yard is 46my and each 10 is 460my.. for instance cretanceous era 146-65 on chart 3.174 yard line. How do you come up with that? How do you get by doing the math to the 3.174? I hope I m making sense. I am totally lost even after seeing the examples. Thanks if you can help.

Answer 20

"It's horrible. I've been staring at this for 5 hours now."
And the worst part is that's not even a joke. This is the stupidest thing. No wonder the question is worth 10 points, it's impossible to do

Answer 21

Left goal line is 4600 Mya.
Each successive 10-yard segment subtracts 460 My.
10-yard line = 4600 - 460 My = 4140 Mya
20-yard line = 4140 - 460 = 3680 Mya
30-yard line = 3680 - 460 = 3220 Mya
40-y line = 2760 Mya
50-y line = 2300 Mya
40-y line = 1840 Mya
30-y line = 1380 Mya
20-y line = 920 Mya
10-y line = 460 Mya
right goal line = now (0 Mya)

Now each individual yard segment represents 46 My, so
65 Mya = 46x
x = 65/46 = 1.413 yard segments... so the beginning of the Cenozoic is at the 1.413 yard line at the right side of the field.

Beginning of Cretaceous is 146 Mya, so
yard line = 146/46 = 3.174 yard line on right side of field

Beginning of Jurassic at 208:
208/46 = 4.522 yard line
