-------------------Earth formed approximately 4.5 to 4.6 billion years ago from a swirling disk of gas and dust surrounding the young sun, accumulating mass through collisions. Gravity pulled this material together, creating a molten, rocky planet that differentiated into a core, mantle, and crust. A major collision with a Mars-sized object later formed the Moon-------------------

a. Centrifugal force
b. 7 bands of light waves
c. 6 types of electural currents
d. Expanding details
e. contracting results coming back to point of origin, now regardless position in the universe here.
