Atlantic Ocean – Voyage Through Time

______

Step 1

You will now measure the distance across the Atlantic Ocean

  • To be successful you must measure the distance across the Atlantic Ocean in the same place on each slide. You may use your Geography book to assist in this part of the activity.
  1. Locate the eastern most point along the east coast of South America. This is the arrow “A”. You should be in eastern Brazil. Mark this point with a “•”.
  1. Locate arrow “B” west coast of Africa. This is arrow “B”. You should be near Nigeria. Mark this point with a “•”.
  1. Put a dot in the same spots on slides.(2, 4, 6, 8, 10, 12, 14, 16, 18, 20). You should end up with 2 dots on each slide.

Step 2:

It is now time to begin measuring the distance across.

  1. Draw a straight line across the Atlantic Ocean between the two points (A and B) you marked on each slide. You will be using the centimeter side of the ruler
  1. Measure the distance in centimeters(Example 2.4 cm) and put the information in the table below

Atlantic Ocean – Voyage Through Time

Frame / Distance in cm / Distance in km
2
4
6
8
10
12
14
16
18
20

If the scale is 1 cm to 4000 km, what math problem must you do to record the distance in km?

Write an equation that you can use to compute this information. When you have written the equation, show it to an adult for approval before completing the last column in the chart above.

______

Step 3:

Finally, use the information you have gathered to complete the line graph below. Remember to use a straight edge to connect your points.

Writing Prompt

You have investigated the movement of the Earth’s major lithospheric plates over time. You have also measured the distance across the Atlantic Ocean over 190 million years.

Writing

  1. Describe, in detail, how the distance across the Atlantic Ocean has changed over the last 190 million years.(Look at your measurements and the graph)(2 points)
  2. Predict what caused this to happen. You must provide at least 2 specific details about your prediction. (Think about the article we read about Alfred Wegener and continental drift) (4 points)
  3. Standard Writing conventions are followed. (4 points)

You must skip lines!!!

When you have completed your writing begin reading it ALOUD. Underline the change in distance only in ONE COLOR.
