Astronomy and Earth

Astronomy: The four rocky planets create the inner solar system, while the four 'gas giants' create the outer solar system.Earth: Tectonic plates consist of oceanic crust and continental crust.

We live in the Milky Way galaxy, which is 100,000 lightyears across

Although the moon goes through phases that we can see, the actual moon never changes.

The Universe was created from nothing, and the laws of physics support this theory!

A great website about planet Earth:

The Earth is made up of the crust (outermost layer), the mantle (middle), and the core (innermost).

Plates move at approximately the same rate a fingernail grows- about 3 inches per year!

There are hundreds of billions of stars.

Messy galazies form into beautiful spirals... because of GRAVITY.

The only thing strong enough to fling stars in sich a manner is a "super massive black hole."
