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.
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
What happens to cause a convection current in water?
Water is a bad Conductor. Note this point! When water at the bottom of the vessel gets heated first, it expands. So its density goes lower. But the comparatively cold water at the top would be with higher density and so they would come down allowing lower dense water to move up. This gets repeated and thus convection current gets produced.
Magma is thought to come from the upper mantle or inner core of the earth.?
false
What are rocks that come from the mantle?
Rocks that come from the mantle are called mantle rocks. These rocks are typically formed deep within the Earth's mantle and can include peridotite, dunite, and eclogite. Mantle rocks are brought to the surface through processes like volcanic eruptions or tectonic movements.
Where does the heat come from that drives convection current the mantle?
uneven temperatures
Where does the heat come from that drives the convection currents in the mantle?
The heat that drives convection currents in the mantle primarily comes from the radioactive decay of elements such as uranium, thorium, and potassium. This heat causes the mantle material to become less dense, rise towards the surface, cool down, then sink back towards the core in a continuous cycle of convection.
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.
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.
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'.
How do convention currents help us understand the geologic activity of the earth?
Convection Current helps us understand the geologic activity of the earth because according to the scientist this current causes the movement of the earth's crust due to the unequal temperature that occurs in the mantle (same also with the breezes). Also, it explains that magma come from th mantle which is believed that the melted crust will spitted up again in the earth's surface which it actually explains the (Theory of Isostacy).

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.
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.
What are convection current and what causes them?
Convection currents are caused by heat dispersal which results in the circulation of material such as air, water, or earth's mantle. Once hot air (or gas) has begun to move, it pushes against adjacent air, mixing until that air reaches the same temperature. Just as you have a cold room with a space heater. Turn it on without a fan, and come back later, the hot air has pushed itself around and warmed the cool air around it.
What words does convection come from?
There are two words that convection comes from; com, and veho
When did the Convection Toaster Oven come out?
tomorrow
