Convection currents occur in the semi-molten mantle. They are created by heat within the earth. As the mantle heats, the rock rises. When it cools, it sinks back down. This movement causes changes in the surface of the Earth.

What does the mantle convection cause?
Mantle convection is the slow motion of the Earth's silicate mantle, caused by convection currents that carry heat from the interior to the surface of the Earth. Mantle convection causes the tectonic plates to move around the Earth's surface, causing earthquakes, tsunamis, and volcanic activity.
What might happen on earth surface if magma rises in a convection current?
Most convection currents exist in the mantle, the layer below the Earth's crust. As the semi-molten rock heats up, it rises closer to the surface as magma and hence cools on the earth surface to form rocks.
What cause the global convection current between the equation and the poles?
Surface currents are caused by wind, and affected by the rotation of the Earth and the gravity of the moon (tides). When the oceans are deep, convection within the layers can also affect the flow of currents. * While wind currents are greatly affected by uneven heating of the Earth's surface, there is no corresponding heating of the ocean bottom by the Sun. So currents do not form spontaneously at depth.

What is the main cause of surface currents in earth?
convection
Which of the folling can form in the geosphere and carry heat from earth mantle toward the surface conduction currents infared currents convection currents or surface currents?
in the atmosphere.
What do convection currents resulting from uneven heating of Earth's surface form?
wind
How do convection currents in the mantle effect lithosphere movement?
Convection currents rotate in the Lithosphere, which causes the surface of the Earth to move.
What causes global convection currents to form?
Differences in temperature on earth
What produced convection currents in Earth's atmosphere?
what produces convection currents in earth's atmosphere
How is the rock cycle related to the movement of earth's plate?
convection currents convection currents convection currents
Do convection currents cause earths heat?
No. Convection currents are the circular motion of earth's wind. If the earth did not rotate, convection currents would not be. Does that make sense?
How is heat transferred from the interior to the surface of Earth?
Via convection currents and hot spots in the mantle.
Convection currents in Earths mantle are believed to be responsible for?
Earth's Plates
What are Convetion Currents?
convection currents are when hot rock from deep inside the the earth rises but cooler rock near the surface sinks
How do convection currents affect earth?
Convection Currents affect earth by slowly moving the tectonic plates
