The Birth of the Earth!

Big Idea:  The composition and properties of the Earth's interior are identified by the behavior of seismic waves.

I can...

• explain what planetary differentiation is and when it occurred in order to form the Earth and other planets in the solar system
• identify the different composition and consistency of each layer of the Earth's interior

Vocabulary:  crust, mantle, core, lithosphere, asthenosphere, mesosphere, seismic waves, composition, convection currents, planetary differentiation, structure, radioactive decay, density

The Birth of our Solar System 

 about 4.6 billion years ago

The Solar Nebula Hypothesis

The Birth of the Earth  - Planetary Differentiation

Our Earth is made!

What about the Earth's Layers?

The Earth's Compositional Layers - divided by chemical makeup

• crust, mantle, core

The Earth's Physical Layers - divided by physical properties - for example - temperature, pressure, solid, or liquid

• lithosphere, asthenosphere,mesosphere, outer core, inner core

What about the interiors of other planets?
