Explain how the movement magma causes earth movement.
Answer:
- When the rocks within the crust and mantle get so hot that they melt, the liquid rock (magma) may flow forcefully (intrude through the lines of weakness). By
so doing the magma occupies space within these rocks. This makes
the displaced rocks to move away vertically or horizontally. If the
movement of the rocks is vertical, the land becomes uplifted and the surface
bulges and if the crustal rocks move sideways, horizontal earth movements are experienced
