By expanding and contracting the core material,
creating pressure waves that drive currents.

Temperature differences in the mantle drive convection currents because warm material is less dense and rises, while cooler material is more dense and sinks. This movement creates a circular flow as the cooler material sinks and gets heated, while the warmer material rises and cools down. The density variations caused by the temperature differences are a key driver of convection in the mantle.

How thick are the convection currents?
The convection currents are in the mantle😱
What causes convection currents it the mantle?
Heat from the core and the mantle itself causes convection currents in earth's mantle.
What separates the mantle and core?
convection currents
What are effects of connection currents in the mantle?
The flow of mantle effects convection currents in the mantle. This process happens as hot material within the mantle begins to rise. As it rises, it begins to cool and then sinks. This process repeats as a cycle of convection currents.
Are convection currents found in the upper or lower mantle of earth?
The upper mantle
Is the heat source for the convection currents in the mantle for the sun?
The difference in temperature and density is the cause of convection currents in the earths mantle. Convection currents are the flow that transfers heat within a fluid.
Is heat source for the convection currents in the mantle the sun?
The difference in temperature and density is the cause of convection currents in the earths mantle. Convection currents are the flow that transfers heat within a fluid.
Is the heat source for the convection current in the mantle in the sun?
The difference in temperature and density is the cause of convection currents in the earths mantle. Convection currents are the flow that transfers heat within a fluid.
Where do convection currents flow in Earth?
Convection currents are found in the plastic mantle in Earth.
Where in the earth do convection currents occur?
Convection currents take place in the mantle.
What would happen to the convection currents in the mantle if the earths interior cooled down?
the convection currents will be set in motion because the heat from the mantle rises and causing it to change Earth's density & force of gravity

What would happen to the convection currents in the mantle if Earths interior eventually cool down?

The layer in which convection currents move?
Convection currents move in the Mantle.
The driving forces of tectonic plates are related to convection currents in Earth's?
mantle.
How are convection currents in the mantle and in the oceans similar How are they different?
The ocean currents are colder than the currents in the mantle,and the are located in different areas.
Is the sun the heat source for the convection currents in the mantle?
The heat in the Earth's interior comes from two main sources: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust and the primordial heat left over from the formation of the Earth.
