Why do volcanoes erupt? I.Because of moving tectonic plate II. beacause of moving water III. beacause of upward movement of magma
Answer:
lll because of upward movement of magma
Explanation:
Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts. If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises. When the pressure is too much an explosive eruption can happen, which can be dangerous and destructive.
