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

2km is the same as 2000m which is the same as 200000 cm. BUT don't make the same mistake as the other answer. This is 200000 cm per 100000 years. Divide 200000 by 100000 to get 2 cm per year. Hope this helps!

The rate of motion of the plates obtained as the ratio of the distance covered over a specific period of time is 2 cm per year.

Time taken to move a distance of 2 kilometers = 100,000 years
The distance moved in 100,000 years = 2 km

Conversion :

1km = 100000 cm
Hence, 2km = (100000 × 2) = 200,000 cm

The rate of motion :

Rate = Distance ÷ Time

Rate of motion = (200,000 ÷ 100,0000)

Rate of motion = 2 cm per year


Therefore, the rate of motion of the plates is 2 cm per year .

The rate of motion of the plate is calculated to be 2 centimeters per year, based on the movement of 2 kilometers over 100,000 years. This calculation uses the conversion of kilometers to centimeters and the rate formula. Thus, the plate moves slowly as is characteristic of tectonic plate activity.
