What causes convection currents it the mantle?
Heat from the core and the mantle itself causes convection currents in earth's mantle.
Mantle convection is a circulation of the heat emitted by the earth's?
core
What are convection currents and where are they found?
Convection currents in the mantle are streams of fluid produced by the process of heat transfer from one place to another. The earth gets very hot as you go nearer to the core. The mantle is thus heated up as it is right next to the core. As a result, convection currents are formed.*Core: It is a spherical zone that lies at the center of the earth.*Mantle: It is the layer surrounding the outer core of the earth.
What would be the greatest effect if there was a change in the Earth's core?
convection currents in the mantle.
Does convection occur in the core of a star?
No, Convection does not occur in the Core. For example, in the Sun, the convection occurs only after the Radiation zone. In the radiation zone the energy is transported by radiation (ie, by photons). At about 0.8 solar radius the density and temperature are not enough to transport the energy by radiation, so convection sets in.
Which layer of the earth is the place where convection occurs?
Convection currents rese and sink through the mantle and the liquid outer core. In Earth's mantle, large amounts of heat are transferred by convection currents. Heat from the core and the mantle itself causes convection currents in the mantle.
The convention that causes earths magnetic field happens in earths?
core
How the convection occur in earth's mantle?
convection occurs in the asthenosphere, which is located under the lithosphere. the inner core heats the liquid mantle and it circles and produces plate tectonic activity.
Why does convection occurs in the athenosphere?
heat from the outer core and the mantle when it drifts up to the asthenosphere it causes convection.
What causes convection currents it the mantle?
Heat from the core and the mantle itself causes convection currents in earth's mantle.
How does Earth's core transmit heat?
By conduction and convection.
What is the main method from core to the crust of earth?
convection
What is the mechanical layer of earth that has the most active convection's currents?
The Earth's core.
Where does the convection occur that causes the Earth's magnetic field?
This happens in the earth's core.
What does the Earth's molten core create?
Convection currents in the Earth's molten core are thought to be responsible for causing Earth's magnetic field.
Which layer of the earth does convection take place in?
convection takes place in the outer core......... i think
Mantle convection is a circulation of the heat emitted by the earth's?
core
