The flowing part of the Earth's mantle, called the asthenosphere, creates convection currents that drive the movement of tectonic plates. As the plates interact with these currents, they can either be pulled apart, pushed together, or slide past each other, leading to processes like seafloor spreading, subduction, and transform faulting. Overall, it is this movement of tectonic plates that shapes the Earth's surface and drives geological events like earthquakes and volcanic eruptions.

What layer in earths mantle do the plates slide over?
The asthenosphere.
The driving forces to tectonic plates are related to convection currents in earths what?
mantle.
How are plates motions connected with motions within the rest of the earths mantle?
convection currents in the mantle provide the basic driving forces for plate motions.
What is rigid layer of earths surface made up of the crust and a part of the upper mantle?
the Lithosphere or Lithospheric Plates
Why are continents not fixed permanently in location on the earths crust?
The continents are embedded in the top side of crustal plates which float on the surface of the mantle. Convection currents in the mantle carry the plates around and the embedded continents travel along.
How does plate tectonics affect the mantle?
Tectonic Plates float on top of the earths mantle, the earths mantle is made up liquid which is always circulating.
What layer are the plates on?
The worlds tectonic plates slide on the earths mantle.
What does it mean to say earths plates float?
plates actually float on earth's mantle
What layer are the plates sliding on?
The worlds tectonic plates slide on the earths mantle.
What are oceans current are formed by what?
Moving plates in the earths mantle.
What layer in earths mantle do the plates slide over?
The asthenosphere.
What causes earths plates to move continuously?
Convection in the earth's mantle.
The driving forces to tectonic plates are related to convection currents in earths what?
mantle.
What layers of the earth compose the earths plates?
upper part of the mantle and end of the crust.
How does convection in the earths mantle help shape the geosphere?
It will move the earth's plates so there :)
What do earths tectonic plates do?
The plates (continental and ocean plates) ride atop the asthenosphere, a layer of viscous rock in the upper mantle beneath the crust.
What would happen to the earths plates if the mantle completely cooled down?
They'd stop moving.
