Plate Tectonics
The earth's plates move very slowly, pressing against one another in some places and pulling apart in other plac…
Item PT022001: A continent would move about 10 feet in 100 years.
How far is a continent likely to move in 100 years?
- About 10 miles
- About 10 feet
- About 10 inches
- A continent will not move at all in 100 years.
1 mile = 5,280 feet 1 foot = 12 inches

- Notes
- The rate of plate motion is not specified in NGSS, although an evidence statement for performance expectation MS-ESS2-3 says that students should "identify relationships (including relationships that can be used to infer numerical rates of change, such as patterns of age of seafloor) in the datasets about Earth features."
