Hi, can someone help me UNDERSTAND this question or something?
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
use a football field for a "time ruler" ... make a drawing
start on the left end of the field ... 4.6 billion years (ago)
mark in the periods and eras based on when they started and stopped
each 10 yards is 460 million years ... each yard is 46 million years
FYI ... our genus "" has been around for about 2 inches
modern humans "homo sapiens" (us) ... a quarter of an inch
Thank you I appreciate your help. Have a good day!
Sure! Let me help you understand the question and walk you through creating the digital model of the football field.
First, let's understand the given information. We are told that the length of a football field is 100 yards. We are also given a comparison between the length of a football field and geologic time. It states that each yard on the field represents 46 million years, and each 10-yard section represents 460 million years.
Now, let's move on to the activity itself. We need to create a digital model of a football field and label the 10-yard lines in years. We also need to draw horizontal lines using different colors to mark the beginning and end of specific periods and eras.
To start, you can use any digital drawing tool of your choice, such as Microsoft Paint or Adobe Photoshop. Open the software and create a new document with the dimensions of a football field, considering the scale mentioned earlier.
Next, draw a horizontal line at the left-most edge of the field and label it as "0 years." This represents the beginning of geologic time.
Moving forward, you'll label the 10-yard lines in years. Since each yard represents 46 million years, each 10-yard segment will represent 460 million years. So, count 10 yards from the beginning line and label it as "460 million years." Continue this process, labeling subsequent 10-yard lines with the appropriate values. For example, the next line will be labeled "920 million years," followed by "1380 million years," and so on.
Now, let's focus on drawing the horizontal lines to mark the beginning and end of periods and eras. The question mentions that the years have been rounded up for this activity, so you need to approximate the duration of each period or era.
Using different colors, draw a horizontal line at the appropriate position on the football field to mark the beginning and end of each period/era. You can refer to a geologic time scale chart to understand the different periods and their approximate durations.
For example, you might draw a red line to mark the beginning of the Paleozoic Era around 540 million years (between the "460 million years" and "920 million years" lines). Similarly, you can draw other lines to mark the beginnings and ends of other periods/eras, such as the Mesozoic Era or the Cenozoic Era.
Remember to label these lines with the name of the corresponding period/era using text tools in your digital drawing software.
That's it! By following these steps, you will create a digital model of a football field with labeled 10-yard lines in years and horizontal lines marking the beginning and end of specific geologic periods and eras.
I hope this explanation helps you understand the question and complete the activity successfully!
