For convection currents in the asthenosphere were does the heat come from?
The heat driving convection currents in the asthenosphere primarily comes from the Earth's internal heat. This heat is generated through the radioactive decay of elements in the Earth's mantle and core. The flow of this heat causes the asthenosphere to partially melt and create convection currents that drive the movement of tectonic plates.
What is the force thought to move large pieces of earths crust including the continents?
Convection-currents in the Mantle, and spreading-ridge pressure from the emerging basalt along constructive plate boundaries. The processes come under the general heading of 'Plate Tectonics'.
For convection currents in the asthenosphere where does the heat come from?
The heat in the asthenosphere primarily comes from the heat generated by the decay of radioactive isotopes in the mantle and the residual heat from Earth's formation. This heat causes the material in the asthenosphere to become less dense and rise, generating convection currents.
In what layer does plasticity and convection occur?
Plasticity and convection occur in the asthenosphere, which is part of the upper mantle. The asthenosphere is a semi-molten layer below the lithosphere where rock can flow slowly over long periods of time. Convection within the asthenosphere is driven by heat from the Earth's core, causing movement of material in the mantle.
Where does the energy come from to drive tectonic plate motion?
The energy driving tectonic plate motion primarily comes from the Earth's internal heat, which generates convection currents in the mantle. These currents transfer heat to the crust, causing the plates to move. Additionally, gravitational forces and the Earth's rotation play a role in the movement of tectonic plates.
Where does the heat come from that drives convection current the mantle?
uneven temperatures
Where does the heat come from that drives this convection current the mantle?
The heat comes from the outer core, which provides the heat.

What are the forces that drives the tectonic plates of the earth?
There are many possible forces or mechanism associated by continental movement.include;sea-floor spreadingthermal plume phenomenaslab-push at mid oceanic ridge.slab-pull at subduction zoneNote that all this mechanism work together
Where does the energy that drives surface currents come from?
Wind
From convection currents in the asthenosphere where does the heat come from?
from the bottom of the earth
In what layer does plasticity and convection occur?
Plasticity and convection occur in the asthenosphere, which is part of the upper mantle. The asthenosphere is a semi-molten layer below the lithosphere where rock can flow slowly over long periods of time. Convection within the asthenosphere is driven by heat from the Earth's core, causing movement of material in the mantle.
Are convection currents important to continental drift?
Convection causes hot magma to rise towards the surface where it turns and flows parallel to the surface as it hits the crust. As the liquid rock flows beneath the crust it drags the crustal plate along and causes the continents that are on those plates to drift.
Where does the energy come from to drive tectonic plate motion?
The energy driving tectonic plate motion primarily comes from the Earth's internal heat, which generates convection currents in the mantle. These currents transfer heat to the crust, causing the plates to move. Additionally, gravitational forces and the Earth's rotation play a role in the movement of tectonic plates.
What best explains why plates move?
Plates move due to the movement of molten rock in Earth's mantle, known as mantle convection. Heat from Earth's core causes the rock in the mantle to flow in a circular manner, carrying the plates above them. This movement is what drives the motion of tectonic plates.
