What are lava and ash? Volcano terms for Grade 3

🌋 What is Lava?

Lava is molten rock that flows out of a volcano during an eruption. Imagine it like super hot, melted candy! 🍬 But instead of being sweet, it's made of different minerals and elements. When lava cools down, it turns into solid rock.

• 🔥 Origin: Lava comes from deep inside the Earth, where it's so hot that rocks melt.
• 🧪 Composition: It's made of melted rocks, gases, and minerals. The exact type of lava depends on which volcano it comes from.
• 🌍 Flow: Lava can flow like a river or ooze slowly like thick honey.

💨 What is Ash?

Volcanic ash is made of tiny pieces of rock, minerals, and volcanic glass created during a volcanic eruption. It's not like the ash you find in a fireplace! 🔥 Volcanic ash is very fine, like powder, and it can travel very far in the wind.

• 💥 Formation: Ash forms when magma (molten rock) erupts explosively and shatters into tiny pieces.
• 🌫️ Appearance: It looks like a cloud of dust and can cover everything nearby.
• ✈️ Hazards: Although it looks soft, ash is actually very harmful to breathe and can damage machines and plants.

🌋 How are Lava and Ash Different?

Lava is molten rock flowing as a liquid, while ash consists of tiny, solid particles ejected into the air.
