the convection currents of lava underneath the earth's crust move the earth's crust.
convection current is magma being heated, and is pushed to the crust, it then cools and sinks to the bottom, where it is to be heated again.

∙ 15y ago== == Hotter zones within the mantle are less dense than areas closer to the crust which have given up energy by heat transfer. Variations in density plus other influences determine the size and activity within a convection cell. The cell can be thought of as a rotating wheel, driven by these energy differences. Positive pressure at one side of the cell and negative pressure at the other drag continental and oceanic plates along.

∙ 12y agoThe Earth's crust is in the form of plates which float on the dense liquid magma of the mantle. When there is a current in the magma, it pushes against the crust floating on top of it. Tectonic plates are very large and heavy, so they don't move easily, but they do move.

The primary cause of convection currents in Earths mantle is believed to be what?
The primary cause of convection currents in Earth's mantle is believed to be thedifferences in densities of earth materialssubsidence of the crustoccurrence of earthquakesrotation of the Earththis was my test question, the correct answer was A
How do you think the convection cell might affect the earths crust?
The way the convection cell might affect the crust above it is that it can cause the earths surface to turn into a volcano. If there is already a volcano there then it will erupt,
How convection currents in the earth's mantle move?
They move because of the heat from the outer core and the mantle.
Why is the earth's crust in constant motion?
Convection currents of heat underneath the earth's crust in the mantle (magma) cause the tectonic plates of the earth's crust to move.
What layer of Earth can you find convection currents?
Convection currents occur in the mantle of the earth. They can affect the crust and the life above it, though.
How does the convection currents cause te crust of the Earth to move?
Because the convection currents involve the Earth's crust.
Which forces responsible for earths crust and lithosphere floating on the mantle?
convection currents in the upper mantle

Convection currents in the earths crust causes volcanos?
No. Earth's crust does not convect. Convection in the mantle, however can create hot spots and rifting, which can lead tot he formation of volcanoes.
Convection currents cause the crust of the Earth to move?
yes by circulation in the mantle
What pulls the earths crust?
The earths crust is moved rather than pulled by things called convection currents. This is when heated rock from the earths core rises up and reaches the crust where it cools. It then sinks down again and carries on in a circle which moves the crust
How does convection currenctions work inside the earth?
Convection currents happen in the mantle and cause tectonic plates to drift. The earth is made up of the iron and nickel core, then the mantle then the crust. And the earths surface is made up of tectonic plates. These plates move due to convection currents.
What effect does convection currents in the upper mantle have on the crust?
Convection currents in the mantle create plate tectonics.
How do you think the convection cell might affect the earths crust?
The way the convection cell might affect the crust above it is that it can cause the earths surface to turn into a volcano. If there is already a volcano there then it will erupt,
How do convection currents affect atmosphere?
convection currents distribute the warm air from the equator towards the north and south pole; they also make the earths crust move causing the earth's crustal features change.
What are some effects convection currents have on the world?
Convection currents inside the Earth happens. The part where the convection currents go up, it brings up materials from the mantle like rocks. This forms new crust. When the convection currents go down, it brings down some older, colder oceanic crust to the mantle, destroying it. In conclusion, the crust is formed and destroyed when convection currents inside the Earth happen.
Where does heat transfer by convection currents take place in the earths interior?
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, and it sinks as it cools. This is how plate tectonics works, as the crust's plates move on these currents.
