Volcanoes prove that beneath its calm surface, Earth remains a living planet. Volcanoes, like Mauna Loa in Hawaii, are effusive. Rather than a violent explosion, lava pours or flows out.

A volcano is an opening in Earth ’s crust. When a volcano erupts, hot gases and melted rock from deep within Earth find their way up to the surface. This material may flow slowly out of a fissure, or crack, in the ground, or it may explode suddenly into the air. Volcanic eruptions may be very destructive.

14 de ago. de 2018 · A volcano is a mountain or hill with an opening. When a volcano erupts, magma is pushed up through the opening with great force. When magma reaches the Earth’s surface, it is called lava. Lava can be as hot as 2,200°F (1,204°C). Some volcanic eruptions are explosive. Lava shoots into the sky. Gas and hot pieces of rock and ash are also released.
