Volcanoes: Exploring the Forces of Nature

TLDRVolcanoes are powerful and dangerous natural disasters that can cause destruction. Learn about the different types of volcanoes, their eruptions, and the associated hazards. Understand the risks posed by active and dormant volcanoes and the measures taken to mitigate them.

Key insights

🌋Volcanoes can erupt violently, spewing out ash, lava, and volcanic bombs.

💨Pyroclastic flows are deadly avalanches of volcanic gases, ash, and rocks.

🌍There are four main types of volcanoes: scoria cones, stratovolcanoes, shield volcanoes, and lava domes.

🔥Lava is molten rock that emerges from a volcano, while magma is liquid rock below the Earth's surface.

⚠️Volcanoes can be categorized as extinct, dormant, or active based on their eruption history.
