The Solar System and the Nebular Theory

What process created the plantesimals (the young version of our planets)?

• Accretion of particles in the solar nebula

• Gravitational pull between the sun and the planets

• The solar wind that blew dust to the outer edge of the solar system

• Nuclear fusion

Which letter in this diagram shows the nebula that was left over after an ancient star exploded?

• a

• b

• c

• d

• e

What word can we use to describe planets that are in the process of forming through accretion?

• planetesimals

• dwarf planets

• asteroids

• meteors

Where in our solar system would you expect to find a planet that is mostly made of gas?

• very close to the sun

• outside of the sun's gravitational pull

• very far from the sun

• very close to other planets

When the sun formed, it blew most of the gasses towards the edges of the solar system. What evidence of this do we see today?

• the gas planets are very close to the sun

• the gas planets are very far from the sun

• there is no gas at all on planets close to the sun

• there is a huge nebula of gas on the edge of our solar system

Our solar system began when...

• The Big Bang happened

• an ancient star exploded around 5 billion years ago

• every other solar system began

• a huge explosion occurred 15 billion years ago

The Nebular 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

• A theory on how the solar system was formed
