How do convection currents cause the earth's crust to move?

Answer 1

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.

Answer 2

== == 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.

Answer 3

The heat from the inner core which rises and produces the convection current, reaches the top of the mantle and begins to cool, but as it passes the crust it produces Friction causing the tectonic plates to move.

Answer 4

The 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.

Answer 5

Convection currents in the Earth's mantle heat up and rise near the core, then cool down and sink back down. This movement creates forces that cause the Earth's tectonic plates to slowly shift and move, leading to events like earthquakes and volcanic eruptions.

Answer 6

As convention happens in the Earth's mantle, the crust which floats on the mantle, moves with the flow of the mantle.
