The crust has the __________ density.
The mantle has a __________ density than the crust.
The outer core is much denser than both the mantle and the crust, while the __________ has the highest density of all layers.
2. Lithosphere and Tectonic Plates
The Earth's lithosphere is made up of the ___________ and the ________; it is divided into large, rigid pieces called __________, which float on the semi-fluid _____________.

Answer 1

Density Differences Between the Layers
- The density of Earth's layers increases as you move toward the core (center).
- The crust has the lowest density.
- The mantle has a higher density than the crust.
- The outer core is much denser than both the mantle and the crust, while the inner core has the highest density of all layers.

Lithosphere and Tectonic Plates
- The Earth's lithosphere is made up of the crust and the uppermost mantle; it is divided into large, rigid pieces called tectonic plates, which float on the semi-fluid asthenosphere.
