Layers of the Earth

 

🌍 Layers of the Earth

Scientists divide Earth into four main layers:

1. Crust

• The outermost layer.

• It’s thin compared to other layers (like the skin of an apple 🍎).

• Made of solid rock.

• This is where we live, and it includes continents and ocean floors.

---

2. Mantle

• The layer beneath the crust.

• Much thicker than the crust.

• Made of hot, semi-solid rock that can slowly flow.

• Movement in the mantle causes earthquakes, volcanoes, and plate movement.

---

3. Outer Core

• Beneath the mantle.

• Made of liquid iron and nickel.

• The movement of this liquid metal creates Earth’s magnetic field 🧭.

---

4. Inner Core

• The center of the Earth.

• Made of solid iron and nickel.

• Extremely hot (hotter than the surface of the sun ☀️), but stays solid because of the high pressure.

✨ Quick Summary:

• Crust → Thin, solid rock, where we live.

• Mantle → Thick, hot, semi-solid rock, causes movement.

• Outer Core → Liquid metal, makes magnetic field.

• Inner Core → Solid metal, hottest part.
