How do volcanic eruptions occur and what effects?

Blogbiz22 Mar, 2023Entertainment

Volcanic eruptions occur when magma, which is molten rock, rises to the surface of the Earth. Magma is formed when the temperature and pressure within the Earth's crust cause rocks to melt. When magma rises to the surface, it can erupt violently, spewing ash, gas, and lava. There are different types of volcanic eruptions, including explosive and effusive eruptions. Explosive eruptions occur when gas bubbles in the magma burst, creating pressure that propels ash, rocks, and lava into the air. Effusive eruptions, on the other hand, involve the slow release of lava that flows out of the volcano.
