The mantle itself moves due to convection currents: hot rock rises, gives off some heat, then falls. How fast do the tectonic plates move in relation to each other? Plate tectonics (from the Late Latin: tectonicus, from the Ancient Greek: τεκτονικός, lit. The Earth is dynamic thanks to its internal heat, which comes from deep within the mantle from the breakdown of radioactive isotopes.
It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. How fast do tectonic plates move? About 2 to 5 centimeters per year (1 to 2 inches per year), about the same speed that your fingernails grow.

GPS and Tectonics. Tectonic plates move because they are floating on top of the mantle.
Continental drift is slow. Another thing GPS can show is tectonic movements within plates. GPS aids us in better understanding our planet by allowing us to measure how the surface of the Earth moves. One assumption behind plate tectonics is that the lithosphere is rigid, and indeed that is still a sound and useful assumption. Just remember that in some places, there will be no movement for 500 years or more, because there was no local event to influence it.

Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. where do plates move towards. This varies from plate to plate. Tectonic Plates: Tectonic plates are giant slabs of the Earth's crust that float on the asthenosphere, which is the upper portion of the mantle of the Earth. They move at a rate of one to two inches (three to five centimeters) per year. If a plate with oceanic lithosphere meets another plate, the dense oceanic lithosphere dives beneath the other plate and sinks into the mantle.

where do plates moves away from. How Do Plates Move? How fast are the earth's tectonic plates moving? We need you to answer this question!

This process is called subduction. Start studying Geo 115 - tectonic plates. Tectonic plates move about the same rate that finger nails or your hair grows (centimeters per year). In total, summing all movements of all sections of plate together, tectonic plates across Earth may move an inch or two a year.

When under extreme stress, the plates can move apart at ever-accelerating speeds, up to a rate of 20 millimeters per year. When they're about to split, the plates can move about as fast as the human fingernail grows, and that's very fast indeed as far as continental drift is concerned. ... how fast do plates move?-as fast as your finger nail grows-0.12 inches/month = 3.7 cm/year.

Geophysicists have discovered something startling about tectonic plates: when under extreme stress, they hit the gas and can accelerate in speed by up to 20 times.
