It takes 100,000 years for a plate to move about 2 kilometers. What is the rate of motion in centimeters per year

1 answer:

8 0

I'm not 100% sure that I'm right here but I tried

100,000 years = 2 km = 200,000 cm
50,000 years = 1 km = 100,000 cm
100,000 years / 200,000 cm = 0.5 cm per year

I feel like I may have done something wrong here but 0.5 cm multiplied by 100,000 gives you 50,000 years and multiplied by 200,000 gives you 100,000 years.

<h3>What is Evolution?</h3>

This is described as the process in which heritable characteristics are changed in species over successive generations. This occurs as a result of natural selection in which the traits suitable for survival are passed to the offspring.

This is usually as a result of a change in the environmental factors which ensures that the organisms are able to adapt so as not to die out and go extinct in this type of scenario.
