Which phrase gives two processes scientists think move the Earth's lithospheric plates?

gravity acting on the edges of plates and convection in the mantle

gravity acting on the edges of plates and friction between the plate and the asthenosphere

friction between the plate and the asthenosphere and pressure of magma on the edge of the plate

convection in the mantle and pressure of magma on the edge of the plate

Convection currents occur in the mantle because the upper mantle (asthenosphere) is generally cooler than the lower mantle. The convections apply upward pressure on the lower edges on the lithosphere as the melted rocks upwell from below. The lithosphere deflects the convections and as the convections churn clockwise of anticlockwise, they drag the lithosphere with it via friction. This is what is stipulated to cause tectonic plate movements.
