Earth is going around right now so its no flat at all lol
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:
c. A dam can significantly reduce or shut off the supply of sediment to a delta.
Explanation:
- The rivers that drain into the ocean have deltas and they form the mouth of the river and the soil rich land is a called as the delta. The dam can significantly stop or shut the supply of the sediments to the deltas.
