How does plate tectonics move continents over time?
ScienceGeology
Quick Answer
Earth’s lithosphere is broken into moving plates that drift a few centimeters per year. Their motion is driven mainly by heat-powered convection in the mantle, plus ridge push and slab pull.
The Full Story
Earth’s outer shell is divided into large and small tectonic plates, including the Pacific, Eurasian, and African plates. These plates move slowly, typically at rates of about 1 to 10 centimeters per year. The movement is linked to heat escaping from Earth’s interior, which helps drive convection in the mantle. At plate boundaries, plates can collide, pull apart, or slide past one another, creating mountains, earthquakes, and ocean trenches.
Key Facts
1.Tectonic plates usually move a few centimeters per year
2.Earth has 7 major plates and many smaller ones
3.Plate motion helps form mountains, volcanoes, and earthquakes
