Why do volcanic eruptions occur?

• Volcanic eruptions occur due to the movement of tectonic plates, which causes magma to rise to the Earth's surface.
• When the pressure of the magma and gases inside the Earth becomes too great, it forces its way through weak points in the Earth's crust, resulting in an eruption.

Answer: Volcanic eruptions happen because of the buildup of pressure from magma and gases beneath the Earth's surface, which eventually escapes through weak spots in the crust.
