🌍 Structure of the Earth – Its Layers (Cores)

---

The Earth is made of layers, just like an apple 🍎
If we cut the Earth from outside to inside, we see 4 main layers.

---

🧱 1️⃣ Crust (Outer Layer)

• The outer skin of the Earth
• Where we live 🏠🌳
• Very thin compared to other layers

👉 Thickness: Like the apple peel

---

🪨 2️⃣ Mantle

• Below the crust
• Made of hot, thick rock
• Moves slowly like sticky honey

👉 Causes volcanoes 🌋 and earthquakes

---

🔥 3️⃣ Outer Core

• Made of liquid iron and nickel
• Very hot 🔥
• This moving liquid creates Earth’s magnetic field 🧲

👉 Protects us from harmful space radiation

---

🔴 4️⃣ Inner Core

• The center of the Earth
• Made of solid iron and nickel
• Extremely hot (hotter than the Sun’s surface!) ☀️
• Very heavy pressure keeps it solid

---

🧠 Easy way to remember

Crust → Mantle → Outer Core → Inner Core

🧩 Simple table for kids

Layer	What it’s like
Crust	Thin, solid
Mantle	Hot, soft rock
Outer Core	Liquid metal
Inner Core	Solid metal

🌟 Fun facts

• We have never drilled to the core 😮
• Earth’s core helps protect life
• Inner core spins slowly!
