Layer´s of the Earth

 

The Earth is made up of four main layers, each with different characteristics:

 1. Crust

• The outermost layer where we live
• Very thin compared to other layers (about 5–70 km)
• Made of solid rock
• Includes continents and ocean floors

 2. Mantle

• The thickest layer (about 2,900 km)
• Made of semi-solid rock (like hot, slow-moving material)
• Heat from this layer causes movement of tectonic plates

 3. Outer Core

• Made of liquid iron and nickel
• Extremely hot (about 4,000–5,000°C)
• Responsible for creating Earth’s magnetic field

4. Inner Core

• The center of the Earth
• Made of solid iron and nickel
• Even hotter than the outer core (up to 6,000°C)

 Easy way to remember:

Crust → Mantle → Outer Core → Inner Core
