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.

Answer: The speed of the earth as it travels around the sun is 67,000 m / ph (107,000 km / h).
Explanation:
The orbit around the sun forms an ellipse and it takes approximately 365.25 days to fully around the orbit, because of that on earth the seasons are experienced throughout the year, as the earth recedes or gets closer to the sun. In addition to the orbit around the sun, the earth rotates on its own axis in about 24 hours giving rise to day and night.
