📚 Topic Summary
Volcanoes are openings in the Earth's crust where molten rock (magma), volcanic ash, and gases escape. Volcanic activity is driven by the Earth's internal heat and tectonic plate movement. Different types of volcanoes, like shield volcanoes and stratovolcanoes, form based on the type of eruption and the composition of the magma. Understanding volcanic processes is crucial for predicting eruptions and mitigating their impact.
