Volcanoes erupt when magma from beneath the Earth's surface is released through a vent or fissure. This happens when the pressure builds up and the magma is able to escape, often with explosive force. The resulting eruption can be incredibly powerful, sending ash, gas, and rock into the air.
Lava is molten rock that flows out of a volcano during an eruption. It can reach temperatures of up to 2,000°F (1,093°C) and can flow at speeds of up to 100 mph (161 kph). Lava can also be incredibly thick and sticky, making it difficult to move through.
Volcanoes can be found on every continent on Earth, and they play a crucial role in shaping our planet's landscape. They can create new land, change the climate, and even affect the air we breathe. Despite their potential dangers, volcanoes are also awe-inspiring natural wonders that continue to fascinate us.
