Earth’s InteriorEarth is not a solid ball of rock!
•Earth has 3 distinct layers:
1. Crust
2. Mantle
3. Core
How are earth’s layers similar to an egg?
Let’s see…

Earth’s CrustWe live on Earth’s crust.
• The crust is the outer layer and it is made of solid rock.
• Earth’s crust is very thin compared to the other layers (only 5-70 km thick)
If Earth were the size of a chicken’s egg, the crust would be thinner than the egg’s shell.

Types of Crust• 2 types of crust:
Continental-crust that forms continents•light & buoyant•made of granite•coarse texture
Oceanic-crust beneath the ocean•dense & heavy•made of basalt•fine texture, dark color

Earth’s Mantle• Mantle-thick layer of rock between crust and core.
The mantle is very hot!Because it is so hot much of the mantle is soft, like melted candy. The rock from the mantle sometimes
comes to the surface as lava through volcanoes.

Since no one has ever been to the mantle or the core, how do scientists know what it’s like?

Parts of Earth’s Mantle
Asthenosphere- Lithosphere sits on top of a hot, softened layer of mantle.
Lower Mantle-The lowest layer of the mantle is solid. Lower Mantle
Upper Mantle
Upper Mantle-a thin layer of solid mantle under the crust.
Lithosphere-the crust & solid upper mantle together

Convection currents carry hot mantle towards the surface while colder material sinks back into the interior.

What Drives the Plates?
The Earth is warmest at the center and cooler
farther out.
An unstable situation: warm material wants to
rise towards the surface!

Tectonic Plates• Earth’s lithosphere is broken into about 17 pieces
• These plates ride on top of the asthenosphere
Tectonic plates move from the mantle’s convection currents.

• The core is the center layer of the Earth.
• It is the hottest layer and can be divided into 2 parts:
Earth’s Core
1. Inner core-solid iron & nickel
2. Outer core- molten (liquid) iron & nickel

Earth has 3 layers:– Crust-thinnest layer
• Continental crust-granite• Oceanic crust-basalt
– Mantle 4 parts:
• Lithosphere- rock of the crust and upper mantle• Asthenosphere-“plasticity” “molten”• Lower Mantle-solid
– Core 2 parts, made of iron & nickel (metals)• Outer Core-liquid• Inner core-solid
