Astronomy 7

Order the following solar system formation events from what happened first (1) to last (5)

• Elements start to collect to form the sun and the planets

• We have the solar system we know today

• The nebula starts to collapse

• The nebula starts to spin faster

• The nebula starts to flatten out into the protoplanetary disk

Why is the sun so big?

• 99.8% of all of the material from the protoplanetary disk accumulated here

• It's made of the heaviest materials in the solar system

• It is made of gases that over time, expanded due to having free space

• Because of all of the chemical reactions that take place in the sun, it continues to expand

Which event did gravity NOT influence in the formation of the solar system?

• The nebula initially collapsing in on itself

• The particles in the protoplanetary disk bind together

• The planets are nearly circular in shape

• The planets are generally ordered from smallest to largest

Select all of the alternatives names to the "outer planets" (Jupiter, Saturn, Uranus, Neptune)

• Jovian Planets

• Gas Giants

• Terrestrial Planets

• Rocky Planets

How many astronomical units (AU) is the Earth away from the sun?

(a)  

Select all of the common characteristics of the inner (terrestrial) planets

• Have the layers: crust, mantle, core

• Have evidence of once having geologic activity (volcanoes, earthquakes)

• Once had ice rings that have since melted

• Have ice at the center of their cores

For what types of distances would it be appropriate to use Astronomical Units (AU) ?

• On Earth

• Within the Solar System

• For objects outside of the solar system

• For all objects more than 1 billion miles away

If aliens who are 10 light years away are looking at Earth, what year is it on Earth from their perspective?

(a)  

In class, we made scale-models of the solar system. Explain why we can or cannot show both the size and distance of the solar system on the same model.
