25. Time Line
4.56 Billion Years Events~ 1) Solar Nebula Forms, A
concentration of hydrogen gas and dust swirling around our
young Sun.
2) Planetesimals Form, Baby planets less than a few
kilometers across form
3) Planetesimals Grow Up to Form Protoplanets,
Planetesimals are large enough to attract material through
gravity.
4) Terrestrial Planets Form
Mercury, Venus, Earth, and Mars form in the hot inner solar
system.
5) Gas Giants Form, Jupiter, Saturn, Uranus, and Neptune
form in the cooler, outer solar system.
26. Time Line
4.5 Billion Years Ago 9) Formation of
Earth's Moon
Earth was hit by a Mars-sized planet.
Debris blown into space around Earth
eventually coalesced and formed our
Moon.
10) Magma Ocean on the Moon! The
coming together of the particles forming
our Moon created heat — enough heat
to melt the outer layer of the Moon!
