Question

What is the scale of the map? For this activity, you will use centimeters.

1 cm = 405 km

Choose one strip of seafloor rock. What is the age of the rock?

20

Use your ruler to measure the distance of the strip from the Mid-Atlantic Ridge.

3 cm

Using the calculator, multiply the answer to #4 by 405 to figure out its distance in kilometers. Round to the nearest whole number.

i multiply 3 by 405 and get 1215 km

Determining Rate of Spreading
Use the age of the rock you have chosen and its distance from the Mid-Atlantic Ridge to calculate seafloor spreading.

First you will find out how fast the seafloor is moving away from the ridge on one side. Use a calculator to divide the answer to #5 by the answer to #3. Round to the nearest whole number.

#5 km ÷ #3 million years = km/million years
