Transcribed Image Text:Tutorial
A tectonic plate has been moving for 81.5 million years over a hotspot, creating a chain of volcanoes
6,815 km long. How fast is the plate moving (in cm/s)?
If there are mountains forming in the north and a mid ocean rise forming in the south, what direction is the
plate moving?
Part 1 of 2
To determine the speed of the plate we need to divide the distance traveled by the time.
distance
V =
time
V =
Use the distance and the time given to calculate the speed in km/s. km/s
Then to convert to cm/s, we use 1 km = 105 cm.
V =
How many centimeters are in a kilometer? cm/s
