🌍 What is a volcano?

A volcano is an opening in the Earth where hot melted rock can come out.

When a volcano erupts, it releases:

• Lava (melted rock) 🔥
• Ash ☁️
• Gases 💨

🔥 What is inside the Earth?

• Deep inside Earth, it is very hot
• Rocks melt and form magma
• Magma stays underground until pressure pushes it up

---

🌋 How does a volcano erupt?

1️⃣ Magma builds up under the ground
2️⃣ Pressure increases
3️⃣ Magma moves up through cracks
4️⃣ It comes out as lava

🧭 Main parts of a volcano

• Magma chamber – where magma is stored
• Vent – path magma travels up
• Crater – opening at the top
• Lava flow – melted rock flowing out

🌎 Types of volcanoes (simple)

• Active – erupting or may erupt again
• Dormant – sleeping, but can wake up
• Extinct – will not erupt again

• Create fertile soil for farming
• Give minerals and geothermal energy

---

🌋 Where are volcanoes found?

• Mostly near tectonic plates
• Around the Ring of Fire 🌍🔥

🧠 Easy to remember

Volcano = Earth’s way of releasing heat and pressure
