6th Grade Density/Earth Layers

Vocabulary

100

The outer layer of the earth. Similar to the skin on an apple. Made up of two other layers.

Crust

200

A thin layer of crust that overlies the ocean basins. More dense, mostly basalt rock, thinner, and younger.

Oceanic Crust

300

 Layers of rock which forms the continents. Less dense, more granite, older.

Continental Crust

400

Solid part of the upper mantle and has plasticity, like a silly putty. This layer is weaker and less rigid.

Asthenosphere

500

Solid outer section of the Earth, which includes the crust (rocky layer). Also includes the cool, dense, rigid upper part of the mantle.

Lithosphere

Earth's Layers

100

What two layers make up the Crust?

200

What layer is the center of the earth?

Inner core

300

What comes before the inner core?

Outer Core

400

What layer is right before you hit the cores? 

Mantle

500

What two major layers make up the mantle? 

Asthenosphere and Lithosphere
