I have a science project type of thing, I'm not asking for any answers. Just a breif and easier explanation on what to do, any help is appreciated.
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]
oh my gosh i need help with this too cant believe it on jiska
I am only askin bc I'm really behind and I need the answers I have truency and I need to submit this pls help
yeah me to I need help
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
Hey,guys thanks for the answers but I need to know how you make the football field tysm!!!
Duh, thats why we're here.
man, im late to this
To complete the activity, you will need to create a digital model of a football field. You can use any design software or application that allows you to draw lines and label them. Here's a step-by-step guide on how to proceed:
1. Set up the dimensions of your digital football field model. It should be 100 yards long.
2. Divide the field into ten 10-yard sections. Each section will represent 460 million years of geologic time.
3. Starting from the left end of the field, label each 10-yard line with the years it represents. Keep in mind that each yard on the field equals 46 million years. Therefore, the first 10-yard line will represent 460 million years, the second 10-yard line will represent 920 million years, and so on.
4. Use different colors or patterns to draw a horizontal line at the beginning and end of each geologic period and era. Make sure to round up the years to fit within the 10-yard sections.
For example, you can start with the Precambrian era, which spans roughly 4 billion years. On your model, you would draw a line to mark the beginning at around the 9th or 10th 10-yard line (representing approximately 4,140 - 4,600 million years ago) and another line to mark the end of the Precambrian era on the appropriate 10-yard line.
Continue this process for each period and era, aligning the lines with the corresponding rounded-up years within the 10-yard sections.
Remember, this is an activity to visually represent geologic time in relation to the length of a football field. The specific divisions and labeling of each period and era can vary depending on the timeline you are using.
With this approach, you will be able to create a digital model that demonstrates the vastness of geologic time compared to the length of a football field.
We cannot create a digital model here.
However, I would reverse the order of calculation, starting with present day at the right.
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
