The Solar Nebula Theory is:
A theory on how the Milky Way galaxy was formed
A theory on how the universe was formed
A theory on how the solar system will be destroyed by a red supergiant
A theory on how the solar system was formed from a cloud of dust and gas

Shake
Turn to ice
A nebula collapses down into a disk known as:
A compact disk
An irregular cloud
An accretion disk
An circular disk
A protostar
A planet
A protoplanet
A planetesimal
In order to form planets, planetesimals have to:
Colliding and breaking apart (fracturing)
Colliding and sticking together (accretion)
Colliding and bouncing around
Breaking down into smaller pieces
Why did the lighter elements stay in the Gas Giants?
Just because the solar wind does not affect these planets
Because they are much less dense
Because it is cold enough for gases to condense and their gravity is strong enough
Because of Jupiter's gravity in the early formation of the solar system

One similarity between asteroids & comets is that they all:
are made entirely of rock
come from the Asteroid Belt
come from the Oort Cloud
orbit the sun
T/F: It is thought that we (Earth) will NEVER be struck by another asteroid or comet due to the fact that Earth is a major planet which has "cleared its orbit".
True
False
T/F: Saturn is the only planet which has rings.
True
False, all Jovian planets have rings
What is the current explanation for Earth's large Moon?
It likely formed just like the planets did around the Sun by gravity pulling the dust and gas into a tight solid sphere.
It was likely a large asteroid which drifted too close to Earth & was captured by the Earth's gravity and remained in orbit.
It was likely formed by a Mars-sized object which collided with Earth, while the material blasted out to space accreted to form Moon.
