The early solar system was made up of mostly what?

• hydrogen, helium and dust

• hydrogen, oxygen and dust

• hydrogen, iron and dust

• carbon, hydrogen and dust

Why does earth have an atmosphere, but mars and mercury do not?

• no liquid water exists on other planets

• the gravitational pull is to strong on mars and mercury

• UV radiation from the sun burns away the atmospheres of mars and mercury and they are too small to generate a magnetic field.

• They just not as "cool" as us.

What two forces keep earth in orbit with the sun?

• magnetic force between sun and earth

• electrical force between sun and earth

• planets travel spontaneously

• velocity of earth and gravity of the sun
