The key difference between a democracy and a republic lies in the limits placed on government by the law, which has implications for minority rights. Both forms of government tend to use a representational system, citizens vote to elect politicians to represent their interests and form the government.
Convection in the mantle and pressure of magma on the edge of the plate
Explanation:
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.
