Drag the following in the correct order of new crust formation:
The crust is carried along by the convection current beneath it.
New crust forms as some of the rising magma cools and solidifies.
The cooling magma begins to sink as the tectonic plates meet another coming in the opposite direction.
As the new crust solidifies, it pushes the existing crust outwards. This is called "ridge push".
The dense tectonic plate subducts (sinks) under the other and melts back into the mantle in a process called "slab pull"
