🌋 Why do volcanoes erupt?

🌋 Volcanoes erupt because there is hot, melted rock called magma deep inside the Earth. When the magma gets too hot and bubbly, it pushes up through cracks in the ground and comes out as lava! 🌋

It's like when you shake a soda bottle and it explodes when you open it—except much bigger and hotter!

🌋 Volcanoes erupt because of the movement of Earth's tectonic plates and the heat inside our planet. Deep underground, rocks melt into magma, which is lighter than solid rock. When pressure builds up, the magma rises and can explode out as lava, ash, and gases!

Think of it like a pot of boiling soup—if the lid is on too tight, the steam will push it open with a big burst!

Types of eruptions:

• 💥 Explosive eruptions (like Mount St. Helens) shoot ash high into the sky.
• 🌊 Gentle eruptions (like in Hawaii) let lava flow slowly.

🌋 Volcanoes erupt due to the complex interaction of Earth's tectonic activity, heat from the planet's core, and the properties of magma. Here’s how it works:

1. Magma Formation

When tectonic plates move, they create pressure and heat, melting rocks into magma. This magma collects in magma chambers beneath the surface.

2. Pressure Build-Up

Magma contains dissolved gases (like CO₂ and water vapor). As it rises, pressure decreases, causing bubbles to form—like opening a soda bottle. If pressure gets too high, BOOM—an eruption happens!

3. Types of Eruptions

• 💥 Explosive eruptions occur when thick, sticky magma traps gases (e.g., Mount Vesuvius).
• 🌊 Effusive eruptions happen with runny magma that lets gases escape easily (e.g., Hawaiian volcanoes).

Volcanoes also shape Earth’s surface and even influence climate by releasing ash and gases into the atmosphere!
